Narrowed Gaze

(Savage Species, page 37, DnD 3.0)

[Monstrous]

Your gaze attack has a limited field of effect.

Prerequisite

INT 13, gaze attack

Benefit

You may choose to limit your gaze attack to an active gaze. Doing so prevents you from accidentally affecting friends with your gaze.

Normal

A gaze attack functions constantly on all those within range, and it can also be used actively as an attack action.
