Invocation Grade: Greater
Equivalent Spell Level: 5th
This blast shape invocation allows you to invoke your eldritch blast as a 60-toot line. An eldritch line deals the normal eldritch blast damage to all targets within the area. This is not a ray attack, so it requires no ranged touch attack. Any creature in the line can attempt a Reflex save for half damage.
