Recover Breath

Type: Metabreath
Source: Draconomicon

You wait less time before being able to use your breath weapon again.
Prerequisite: Con 17, breath weapon.
Benefit: 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.
