Its happened 2 me twice and I'm pretty sure its repeatable.
I have an 18 bard / 2 rogue.
He has the diehard feat from Unyielding Sovereignty and his unconscious range is like 265.
When he goes unconscious, he does not die, nor does he wake up.
So far Ive let him lay there for up to 30 minutes.
He was minus 234-ish hit points with +20 temporary hit points.
The temporary hp comes randomly from one of my enhancements and somehow
Are not negated when I get hit.
The result is:
- Im not dead because Im above -265
- Im not concious because Im in negatives
- Im not unconscious because I have temporary hit points
So Diehard doesn't revive me and I just lay there
I waffled back and forth about recording it but ended up not doing so.
