From publisher blurb:
This installment of the More Feats! product line introduces a new kind of feat: the sin feat. Sin feats are designed to represent a character’s vices and moral failings, though they are by no means restricted to evil or non-good characters. Though a few sin feats are supernatural in nature, and some even grant bonuses of the profane type, characters of any faith or alignment may wrestle with sinful vices – grappling with and overcoming such a moral complication often serves to highlight a character’s heroism.
Feats of Envy includes twelve new feats for envious sinners: Acquisitive, Arcane Jealousy, Conniving Companion, Covetous Counterspell, Curse of Cupidity, Deny the Gods, Embittering Aura, Envious Spell, Jealous Heart, Perilously Paranoid, Steal the Limelight, and Wicked Wish..
