Eldritch Eye (3.5e Invocation)

This blast shape invocation allows you to invoke your Eldritch Blast as a ray emanating from your eye. An Eldritch Eye Blast functions as a normal Eldritch Blast except that any spell-failure chance caused by armor is ignored. Furthermore, an Eldritch Eye Blast may be used as long as line of sight and line of effect are not blocked and and that the invoker may move its eyes.

Finally, the invoker may choose to concentrate on a target that the Eldritch Eye hit. Doing so provokes attacks of opportunity. If it is possible for concentration to be broken, the invoker must roll a concentration check as if this ability was a third level spell. As long as line of effect, line of sight, and the ability for the invoker to move its eyes is not broken, the invoker gets a +5 insight bonus to attack rolls against that target on the next round.
