Invulnerable Blood Ability: How do you handle it?

[Rhiannon Faramiriel]

Hi All,

In the campaign book "Blood Enemies" there is a blood ability Invulnerability. I'm not new to the campaign setting, but this blood ability has always left me wondering what the best way would be to handle it.

I would like to get the general vibe for how y'all handle PCs and NPCs with the Blood ability of Invulnerability.

Do you treat it like Achilles? Nothing can harm him except the shot through the ankle?

Do you treat him like Rogue from the X-men? The character can have the tar beaten out of them but nothing breaks the skin or breaks bones?

This brings me to my next issue:

How do you handle a bloodtheft attack on a character so endowed? Do you have to find their weakness and meet those conditions before bloodtheft can occur or do you allow a nat 20 through the heart to be an automatic bloodtheft that defeats the special conditions of that blood ability?

Thanks,

Jenn

BRCS playtest says this about the ability:
Invulnerability
Level: Great*
Derivations: Azrai, Basaïa, Vorynn
This ability grants the scion a limited form of immortality. He
is not immortal in the true sense of the word, but he cannot be
killed except under very specific circumstances. *Only characters
with the Bloodform ability, the Bloodtrait ability, or the
Great Heritage template may take this ability.
Great: A scion with Invulnerability can be killed only under
a particular set of deadly conditions, which are unique for each
blooded scion. The scion cannot be slain save through this
vulnerability. The scion is immune to all polymorph and magical
death effects. The scion cannot be slain by poison, nor can
any effect reduce their ability scores below 1. If reduced to
negative hit points the scion is rendered unconscious but can’t
be reduced below –10 (such damage in instantly regenerated).
A scion's vulnerability may be as simple as a vulnerability
to magical weapons to as complex as a need to sever his limbs
and burn them to ash. Unless the appropriate vulnerability is
exploited, the scion regenerates at their normal rate. This ability seems more geared for villains than PC's (unless of course your PC's are villains). It seems reminiscent of how a lot of the types of monsters in Ravenloft that make unique npc plot villains (hello Van Richten's Guides) have allergins that are specific to each individual character. This usually is designed to pull the PC's into the roll of investigators trying to figure out how they and truelly destroy their advarsary and keep them from coming back. Along this whole process they can even have scrapes and tussles with the villain. Causes for all kinds of plot and suspense. Usually the vulnerability is somehow relevent to the flavor and history of the individual. In undead it might be what killed them, something they coveted in life, or something that represents their folley and how they wound up where they are at. In a construct or item, It might be related to how they were made (Frodo's Ring comes to mind) In anything it would somehow symbolize their character or how they came to get that blood ability anyways. With the prerequisites to the ability there should be a lot of background to work from.

I immagine the visual effects of this would manifest differently and would be up to your descretion, for instance, peircing them through the heart may actually peirce and draw blood, but actually does no damage, the creature might just smile and laugh, that is until its invulnerability is removed and then it is stabbed through the heart again. Or it could just go in and out like a ghost. The creature could turn into ash at -10 only to reform again angrier than before, or the bloodthefting weapon if non magical could rust or disintigrate when the coup de grace is attempted or just bounce off like the chest cavity was made of solid rock. It would be interesting to look at if it would be possible to bloodtheft the creature after the specific vulnerability was used. For example, If Dorian Gray was a scion with this ability, and he could only be destroyed if he looked at his portrait that captured all his evil deeds, otherwise damage he took was just applied to the magical portrait instead, then making him look at his portrait, at which point the trade places, he ages, takes on all the evil, corruption, and damage that he should have throughout the years, and dies, well if his heart wasn't peirced would the PC's that forced him to meet the gaze of the portrait not get his bloodline? or would it go to the person who peirced him in the heart 5 years ago and it did nothing at the time, OR would he explode in a shockwave of resounding blood energy for those who slew him to take? This I imagine would be up to the DM and maybe the PC's wouldn't even know until the deed was done. That could be fun.

Thanks Ausrick.

That is what I suspected and was leaning toward.

Merci beaucoup,

[Osprey]

IMC I only allow a scion with a True bloodline (any derivation) to possess Invulnerability. Given this is by far the most powerful blood ability in the game, and well beyond the scope of other Great abilities (see "Designing New Blood Abilities" in the BRCS, Chapter 2), it seemed all too appropriate to make it soley a True bloodline ability only. This limits it to the few ancient awnsheghlien in the world, and keeps it out of the reach of PC's altogether.

Osprey

[Rhiannon Faramiriel]

Hi Osprey,

Thanks for your take on it.

That would mean reworking some of the awnsheghlien from Blood Enemies as most of them aren't True. If memory serves, the Magian is not True unless he was present at Desimaar.

I read somewhere that he was one of the Lost, but I think Blood Spawn contradicts that notion as he wasn't listed in the table.

J

[ausrick]

Semi-related, how does an undead Awnsheghlien, especially a skeletal one (BRCS playtest says Awnsheg can be based off of an undead creature, and I don't have any books on it but I think I remember someone telling me the Magian is kind of like a Lich) handle having a bloodline? Is it actually blood and how do you Theft it per se? Do they somehow still have a heart or is just a chest cavity good enough? Or is the Magian kind of like General Grevous from Episode III?

[Rhiannon Faramiriel]

Maybe he's more akin to the "Mummy" (gooey) rather than skeletal form. I tend base the Lichs in my campaign around the "Van Richten's Guide to same", many of the illustration would suggest at least partially flesh covered frame.

Or it could be related to a Lich's phylactery.

Jenn

[ausrick]

Good Idea, skeletal AND goey, gaunt and boney, yet covered in decaying flesh, at any rate the blood would be kinda thick, and black. Firan Darcalus Zal'honan the Azal Lan eat your dessicated heart out! ;)

[geeman]

A few things to note about committing bloodtheft on an awnshegh (or
ershegh, I suppose) character whose body has been substantially altered
and/or who has the Invulnerability blood ability:

1. The difficulty of performing bloodtheft should be accounted for as part
of the character`s transformation. That is, let`s say The Blob is
transforming into some sort of gelatinous form. Technically, there`s
nothing about that transformation that means the character can`t be stabbed
through the heart. His heart might float about inside his body
willy-nilly, but it`s still there and the character should still be under
the threat of bloodtheft. If, however, the DM and the player decide that
the transformation is going to reach the point where the character no
longer really has a heart--his cytoplasmic innards are too nonhuman to
really continue to serve that function, then the immunity to bloodtheft
should be accounted for as part of the character development/levelling up
process. It should be factored into whatever method is used to assign
powers and abilities to the character.

2. When it comes to performing bloodtheft on characters with the
Invulnerability blood ability, however, I think it would be doable to just
rule that the character is immune to bloodtheft under most
circumstances. Since it is a "great" power and actually prevents death one
could simply rule that it renders the person with that ability unkillable
by a stab through the heart and, therefore, impossible to really perform an
act of bloodtheft upon. We can probably presume that it is the godly life
energy that is stolen/transferred during bloodtheft, so if a character`s
mortal energy remains in his body when he would normally be "killed" and it
is his divine energy that sustains him then that divine energy isn`t
released either.

The write up for Invulnerability that I use says that:

You are only killed after a special procedure is performed after you are
reduced to -10 (or fewer) hit points. The procedure is a relatively simple
one, but not one that would occur "naturally." That is, it is a process
that requires several steps using fairly common items. For instance, your
body must be burned, decapitated, and sprinkled with holy water. Learning
the method by which you can be killed can be done with spells like Legend
Lore or Divination. You are now effectively immune to bloodtheft unless
the special procedure necessary to kill you includes being stabbed through
the heart.

3. It should also be noted that stabbing through the heart is not
necessarily the only way to commit bloodtheft in the original
materials. Certain awnsheghlien (the Vampire, for example) have the
ability to commit bloodtheft by sucking the blood of their
victims. There`s no reason why that ability should be exclusive to the
Vampire--though it might have different manifestations. Other characters
might "commit bloodtheft" after having swallowed a scion`s body whole,
performed arcane rituals, been the subject of some bizarre version of the
Land`s Choice or otherwise being the subject of a mystical process of
transference. Since the rules for D&D combat are abstract, the specific
game mechanics for a "stab through the heart" are really just portraying
"an act of bloodtheft." What I mean by that is that bloodtheft is usually
described as a stab through the heart, but the particulars of the coup de
grace with a piercing weapon (or whatever other specific one wants) don`t
necessarily have to be interpreted as a stab through the heart. It could
be anything that inspires the act of bloodtheft. If an awnshegh was
transformed into The Crystalman, for example, an act of bloodtheft might be
performed on him with a bludgeoning weapon that shatters the ruby red
crystal that his head has evolved into.

Gary

[DemyztikX]

It could also be ruled (and this is simple compaired to the others) that his heart must be pierced (assuming he still has one) AND he must be killed.
So Achillies would first have his heart penitrated and then killed thru his ankle.
Simple, not as good as some, but not as powerful as being immune to bloodtheft.

The BRCS seems to be pretty clear on this......if you are undead you have no bloodline,period.

[Doyle]

One of the many little inconsistancies in the stuff that all the players have read, but they won't know which version the GM has chosen.

IMC a dead character has lost their bloodline even if resurected. The Magian, while haveing most of the attrubutes of a lich is more akin to JK Rollins Voldemort. It would certainly not hurt The Magian to be feared as a lich while being something else that the PCs don't expect.

As to bloodthefting a powerful Awnsheigh (the only characters that should have such an invulnrability IMO), I'm happy to let the one method of killing them also be the means of bloodthefting. IMC the blood form that once afflicted the Awnsheigh now afflicts the slayer.

my 2 c.p.

Help me out here.

Where is it specific on the fact that if you are undead you have no bollodline?

It is clear that when you die you lose your bloodline, but you can attempt to regain one afterwards. Under resurrection it talks about it - basically I don't see where it denies this for those being raised as undead.

I can see how a suit of armor with the blood protection ability could be used to aid in the effort to maintain a bloodline when transforming into a lich.


Chap 2:




People, animals, and on very rare occasions, even objects in the immediate area of a scion's violent death may absorb a portion of the scion's divine essence. This burst of divine energy can be measured in the form of RP equal to five times the victim’s bloodline ability score. The radius of this burst of energy is equal to one foot for every point of power released. For example, a scion with a bloodline score of 20 is slain in combat; the result burst of energy will have a radius of 100 ft. This burst of energy is not affected by the scion’s current regency reserve (which normally passes to her invested heir), but from her very body.





Becoming blooded through usurpation

Non-blooded creatures exposed to divine energies released during usurpation may spontaneously become blooded. This occurred on a massive scale at Deismaar and transformed its heroes into the first scions. If a non-blooded character absorbs RP from a source whose derivation agrees with their basic nature, they may become blooded.



Chap 3:




Resurrection

Resurrection is a rare occurrence in Cerilia. Although it is certainly possible to Raise Dead, most clerics are loath to do so. Firstly, death is assumed to be the providence of the gods. Only in the most unusual circumstances (and for the greater good) would most clerics choose to interfere with the will of the gods and rip a soul from its place of earned reward or punishment.



Secondly, when a scion dies, the vital energy of their bloodline is released at the moment of their death and absorbed by those nearby. A resurrected character's bloodline is gone forever. They have no bloodline score and are not a scion. They can certainly attempt to gain a new bloodline through investiture or bloodtheft, but their original bloodline can never be restored.







Chap 8:




Blood Protection: A suit of armor with this enchantment protects the wearer from losing his bloodline through bloodtheft as if protected the Bloodline Ward realm spell. The character's bloodline is retained in the armor and can be released only by the touch of one of the slain scion's descendents (who absorbs the bloodline as per a Bloodline Investiture realm spell). The presence of the bloodline cannot be detected by common magic and can only be destroyed if the armor is destroyed. A suit of armor with this ability cannot store more than one bloodline at a time. Caster Level: 12th; Prerequisites: Craft Magic Arms and Armor, scion, bloodline ward; Market Price: +3 bonus.

Well, first off, as Irdeggman notes there`s no reason why an intelligent
undead creature can`t have a bloodline. Supposedly bloodline is lost if a
character is killed and brought back to _life_ but a character who "dies"
and becomes "undead" is a bit different, and we don`t really have a ruling
on that.

Secondly, when it comes to the Magian, he may not actually be "undead" in
the sense that he is really a lich. I haven`t seen a 3e write up of that
character, but in 2e there were some differences between that character`s
description and the powers/abilities of a typical 2e lich, which leads me
to suspect he was not intended to be a lich, but an awnshegh whose theme
was that of a lich-like creature. The magian is no more undead than the
Serpent is _really_ a snake, or the Spider an arachnid. They are humans
whose divine (infernal) blood has transformed their bodies into those
forms. Similarly, the Vampire is a vampire in name and theme, but not in
the sense that he is a "standard" D&D vampire. All of these characters are
unique creatures who have taken on a process of transformation that is
similar to that of another kind of monster, but they remain essentially
transformed humans (or a goblin in the case of the Spider) rather than
actually becoming a type of monster in the sense that their basic "type" is
changed.

[Question]

Huh.....i guess i must have mis-understood it.My understanding was that you couldnt have a bloodline as undead because you were dead in the sense.

It is kind of a hinky distinction that requires more than a little
interpretation, and several aspects of it could go either way. For
instance, I would personally rule that any scion who was killed and
then raised as an undead creature would lose his/er bloodline because
I think the important aspect of the loss of bloodline that occurs
when a character dies and then is raised (by a clerical spell) is the
actual dying part. The godly energy that resides in a creatures body
is dispersed by death just as the godly energy was originally
released from the gods themselves when they died. Most undead
creatures go through a process of dying and resurrection that is
enough like the rule about a scion who returns to (mortal) life
losing his bloodline that I would apply the same rule to both processes.

That said, it is entirely possible to have a BR-specific type of
undead (spectral scion, for example, only exist in BR) and rule that
such a creature retains its bloodline after death as a kind of
special case. I`ve got a monster that I`ve been mulling over called
the Fear Gortach which is a kind of haunting effect in a certain area
where a scion has been killed by a stab through the heart that did
not result in an act of bloodtheft. If the scion is killed by a
commoner or otherwise dies in an act that would normally result in
the release of his bloodline there is the potential for his soul to
become "rooted" to the spot that he died as a malicious spirit,
trapped in the world of the living. (IIRC in the BRCS Update any
time a scion is stabbed through the heart it makes for a sort of
bloodtheft situation, but originally bloodtheft only occurred
predictably when a scion was stabbed by another scion, and I prefer
that, so I don`t use the "exploding" scion version.) The Fear
Gortach for reasons of theme, therefore, retains its bloodline.

When it comes to issues of bloodtheft or otherwise acquiring a
bloodline there`s no reason I can think of that would prevent an
undead creature from gaining one after it rises in its undead
form. There are a few methods for acquiring a bloodline (the Land`s
Choice, inheritance) that would work. In the case of the Magian, he
may or may not actually be undead, but as a member of the Lost
(pre-Deismaar wizards who were empowered by Azrai with the ability to
wield true magic) he might be a character who became a lich, retained
his power to cast true magic and THEN acquired a bloodline by some means.

Gary

[ausrick]

It is a logical assumption Question, one I had to work through as well. My players were all under the same assumption. The act of death causes the loss of the bloodline, and the general pre-requisite for being and undead is in fact dying. It isn't too much of a stretch though that if a character underwent some sort of transformation that made them undead (or undead like) without the actual dying (Like I'm assuming becoming an awnseghlien that resembles an undead creature) they could retain their bloodline. Also, how Irdeggman mentioned, there are ways magically (magic item) to bind a bloodline and thus cheat bloodtheft/death. What I've come to realize from this discussion has been that blood doesn't exactly have to be what contains the devine energy per say. What I mean by this is it doesn't exactly have to be pumping, or it could more resemble ichor, bug juice, or whatever psuedo-vascular sytem or liquid a slime or jelly would have. It is kind of the symbolism of the internal (un)life-sustaining liquid/juice/energy. And what a lot of people are saying, is that the Magian might not even be actually undead at all, just a lot like it, or received his bloodline afterwards. All of these posts that you all have put here give me so much inspiration.

[ausrick]

People, animals, and on very rare occasions, even objects in the immediate area of a scion's violent death may absorb a portion of the scion's divine essence.

Just a fun note on this point that Irdeggman quoted earlier. In the campaign I am running, one of my players previous characters (a scion) from a few sessions ago got mauled by a dire bear, hence the re-roll of his character. It could be funny if this Direbear made an appearance again in the campaign but with a bloodline. Any thoughts? What would that even do to an animal?

And for those thinking I am mean, He was a level two character, and went to the local wanted board outside the city hall, and I gave him about 20 pre-made posts for things wanted (all of verying potential and difficulty), and he jumped all over the add from a local wizard who wanted the corpse of a Dire Bear. The rest of the party all said he was nuts and they didn't have time for this but he would not be swayed. The Druid PC said he would have no part in this unnecessary slaughter. The bard PC made the joke to our would-be hunter that "If he wants to get the Druid's approval, then for every bear he takes from the Erebannien, he must then plant two bears." and then wrote a song about the great bear hunter, telling him that he would have the rare chance to hear the ode to his bravery before he perished, when they were typically written. His fellow compatriots chiding and laughing did not disuade him. He went in search of a guide. An NPC ranger who had survived a mauling showed him his scars. He still was determined. Finally he found a guide brave/stupid enough to take him on the hunt. I kid you not, the Dire Bear (CR 7) killed him in one round, sent him to -26. It's not like I did this to a 10 or 12 year old who had never played, this man is 27 and says he has been playing since he was in elementary school. Later he said to me that "It wasn't fair because he didn't know he could die". He's been playing in my campaign for months and I told him when he rolled up his character that I make it as real as possible, death can happen.

Sorry for the story of digression, just wanted to share that. And let you guys know that I don't let my players solo things 5 CR higher than themselves out of sadistic pleasure.


So the question, should the Dire Bear get a bloodline? and what would it possibly look like if an animal receives a bloodline, whould they even have the intelligence to use it? And I would say getting mauled as bad as he did, it probably had a good chance of peircing his heart with his claws. IIRC when it happened I described the last thing he saw was massive paws bigger than his torso come down onto his chest and his vision suddenly jerked back to the trees behind him as if flying through the air, so for all he knows he might not even have a heart left or have even been decapitated.

[Rhiannon Faramiriel]

Perhaps it is just some unique aspect of the Magian's bloodform. At the moment he was changed, he became lich-like or "undead". Somewhat like the Nazghul.

"They are the Nazghul; Ringwraiths. They are neither living nor dead."

If he is one of the Lost (contraditions again), then maybe it was the Unique nature of the Shadow World that has given him his "lich like" quality.

I think the Magian would be more like Sauron before he lost his ring
than one of the Nazghul. His riders are, after all, more on the
order of ringwraiths than he is.

We know very little about the Lost other than they had access to
magics beyond that normally available to humans. Exactly how this
changed them if at all is a matter for conjecture. Personally, I
like the idea that they had some sort of negative effects, but I
don`t think there should necessarily be any one manifestation of that
process. That is, being a member of the Lost might have effects
similar to being an awnshegh in that it transforms a person
physically but in a way that is unique for each character. That
would support the fact that there are many more awnsheghlien than
ersheghlien despite there being more scions of the other bloodlines,
it helps explain the nature of the Lost by drawing a parallel between
the power of bloodline to allow humans to cast true magic, and lastly
it hints at a connection between the process of bloodline
transference that happened so dramatically at Deismaar. That is, if
Azrai could "infuse" the Lost with some of his divine energy to allow
them access to true magic then that is another example of how
bloodline is transferred in the first place, helping to justify the
setting`s backstory.

Why is the Magian being a member of the Lost a contradiction? Does
it say flat out that he is not in some other source or give some
other definitive explanation of his origin?

Gary

[irdeggman]

Creatures gaining bloodlines:



From Blood Enemies.



The Boar. {And the description of the the bloodtheft sure sounds a lot like the BRCS version. “. .. a wild maelstrom of energy erupt from the corpse of the nobleman. Some of the energy lept into the boar, turning its coat white and increasing its size by more than half!. The rest of the vortex felled a number of trees all around and blasted the ground beneath the corpse to bar rock.”}





The Hydra

Kraken (?)

The Leviathan

Pegasus

Stag of Sielwode



The description for the boar does a pretty good job of portraying how an animal becomes blooded IMO.

[Rhiannon Faramiriel]

If I remember the Bloodspawn table, the magian is not listed among their number. However, it is eluded to elsewhere. Maybe not a contradiction, just a gap in the info.

Ah, OK. IIRC, the info on the Magian in CotS text and Blood Enemies
are amibuous about his origin. It`s in Bloodspawn that it says flat

I`m sure your right. It adds to their mystery a bit. Plus, why go
into too much detail about them since they are A) Long gone (for the
most part) and B) Represent a very small number of characters.

I think there should be a good, story related way to bypass the invulnerability. In my campaign the only way to get Rasaene was to fight him on the battlefield where Roele fell, Harness the bloodline Michael invested the grounds with, and then when Rasaene tries to gaze attack, you have a gaze reflection spell cast on him, turning himself to stone. Then with the Sword of Roele (recieved by the three brothers mages after success in The Sword of Roele module) cut off the Gorgons head.
Then in the Shadow world the process is repeated.
Of course that might be too difficult for most PC's but if they manage to succeed they will sure feel like they did.

[sergai]

Now I don't play BRCS I use second ed on top of just 3rd ed characters (which runs wonderfully :) ) but has anyone considered you could just capture an invulnerable keep him beaten down to -10 hp and then have a priest use the divestiture action? I'm pretty sure the creature can die when he doesn't have a bloodline anymore ;)

Good Idea, i like it. Adding Invulnerability to the Gorgons Bloodabilities would make him much more dangerous. The pc have to think how to kill him and not only look at his stats.

Clever very clever.
Is this allowed to divesture a bloodline when the scion has invulnerability.

What about: such spells like suppress blood ability or suppress bloodline?
If the Spider for example has it bloodline suppressed and is killed(-10hp), what happens? Is the Spider dead and its bloodline leaves it and is gone or does the invulnerability save it and the process of rebuilding starts at the end off the spell who suppressed the bloodline.
