Noxious Undead (3.5e Feat)
From D&D Wiki
 Noxious Undead [Necromantic]
Your fleshy undead creatures have a sickening smell
Prerequisite: Able to create undead
Benefit: When you create an undead creature you may choose to add an amber gemstone worth at least 50 gp to the material components of the spell. If you do, the undead creature gains a 10ft. radius of stench like a Ghast. If the creature is a Ghast, then its stench DC is increased by +2. An undead created in this way counts as one Hit Die higher for the purposes of creating it and controlling it. You can only raise an undead creature's effective Hit Dice to one half your caster level through Necromantic feats.
Special: This feat may only be applied to an undead creature mostly composed of flesh.
