Special Abilities
Martial Proficiency (Ex) Sinspawn are proficient in all simple and martial weapons, armor, and shields (except tower shields).
Sin-Scent (Su) Sinspawn can smell the presence of creatures whose nature reflects the sinspawn’s sin. For example, lustspawn can scent creatures that are especially desirous or lustful, at the GM’s discretion.
Sinful Bite (Su) A creature bitten by a lustspawn is overwhelmed with lust (DC 14 Will save negates). These unfettered impulses and emotions are so powerful that the target becomes sickened for 1d6 minutes. An affected target that is bitten a second time is staggered if it fails its saving throw. Additional failed saves increase the duration of this effect but do not increase its severity. Calm emotions, remove curse, or break enchantment negates the effects of sinful bite. The save DC is Charisma-based. This is a mind-affecting effect.

Treasure standard

Sinspawn are corrupted products of magic used by spellcasters in a past era as shock troops for their armies. Literally the embodiment of a sin made flesh, they are sentient abominations of distilled ectoplasm imprinted with the soul-image of slain creatures that possessed an abundance of a particular sin.
