Widen Supernatural Ability

(Tome of Magic, page 75, DnD 3.5)

[General]

You can increase the area of your supernatural abilities.

Prerequisite

8 HD, supernatural ability

Benefit

Once per day, you can widen a supernatural ability. When you use a widened supernatural, ability, its area increases by 100%. Thus, a widened line or cone is double the normal length, and a widened burst, emanation, or spread has twice the normal diameter. You must declare use of this feat before you use the ability. Widening a supernatural ability does not require a separate action.

Special

This feat can be taken multiple times. Each time it is taken, you can widen a supernatural ability one additional time per day. You cannot widen a particular use of a supernatural ability more than once.
