Description: -1 round for Breath Weapon to Recharge

Prerequisites: Breath Weapon, CON 17

You reduce the interval between uses of your breath weapon. You wait 1 round less than usual before breathing again, but always at least 1 round. The feat stacks with the effects of metabreath feats, reducing the total time you must wait to use your breath weapon again by 1 round.

Special

If you have multiple heads with breath weapons, all breath weapons use the reduced interval.
