Supernatural Virulence (3.5e Feat)
From D&D Wiki
Supernatural Virulence [Fiend]
Your poison is as much magical as it is biological.
Prerequisite: Must have a poisonous natural weapon.
Benefit: Choose one of your spell-like abilities of 3rd level or lower. Any time you successfully poison a victim, they are also targeted by this spell-like ability as if this effect was cast (this expends one use of the ability). While poisoned with your venom, the victim cannot be effected by your spell-like ability again.
