Spider Bite

( Player's Guide to Faerûn, p. 176)

[Vile]

You gain a poisonous bite like that of a spider.

Prerequisite

patron deity Lolth, Verminfriend (Book of Vile Darkness),

Benefit

Your saliva is poisonous when ingested by or introduced into the bloodstream of another creature. You can inject this venom while grappling a foe that has exposed skin by making a successful grapple check. The Fortitude DC to resist this poison is 10 + 1/2 your character level + your Con modifi er. The initial and secondary damage ratings are the same (1d4 points of Strength damage). Your kiss is also poisonous, and you can use your saliva to poison food or drink, though when the poison is ingested, the save DC is reduced by 2.
