Enlarge Breath

(Draconomicon, page 70, DnD 3.5)

[Monster]

Your breath weapon is larger than normal.

Prerequisite

CON 13, breath weapon

Benefit

The length of your breath weapon increases by 50% (round down to the nearest multiple of 5). For example, an old silver dragon breathing an enlarged cone of cold produces a 75-foot cone instead of a 50-foot cone. Cone-shaped breath weapons get wider when they get longer, but lineshaped breath weapons do not. When you use this feat, add +1 to the number of rounds you must wait before using your breath weapon again.
