Re: Feats for Halloween![3.5, PEACH]
Candy Lover's Sugar Rush ability is pretty overpowered for two reasons: first, it doesn't specify what type of action (extra full-round action? Sweet!), secondly, extra actions are overpowered in the first place. Sure, it takes two feats and only last one round with minimum investment, and there aren't enough feats to make it last much longer than three rounds, but it's still something that people would kill for very often.
The best answer is always to ask your DM.
Unless you're the DM, in which case you should talk to your players.
