Several Assassin Handbooks out there (eg. this one) seem to reference a certain feat.
Favored in Guild – Jazred Chalssin (DMG2+web): +4 DC [of death attack]. Tied pretty tightly with anti-Lolth rebel fluff.
I can't seem to find the given web enhancement. Even after decoding the nonfunctional link given in the handbook, it only leads here.
Does anybody know of the enhancement? Is there anybody who has the link or correct text?
