Eldritch Flames
The caster summons forth sorcerous flames that cause damage equal to their spell rank every round a character passes through them. A spell rank FEAT roll is required to bring them forth. The flames are summoned forth in a fixed location, designated by the caster, and cannot be moved. The flames are used as a fiery wall to block movement into or out of the target area. They extend along 1 side of the target area chosen by the caster and can be any height chosen by the caster, from a few feet to 3 stories. The wall of flames can be slightly bent by the caster to accommodate structures and obstacles. No more than 3 walls can ever be maintained by the caster at any 1 time.
