Invocation Type: Lesser; Eldritch Essence
Spell Level Equivalent: 3
This eldritch essence invocation allows you to change your eldritch blast into a brimstone blast. A brimstone blast deals half fire damage, half magic damage. Any creature struck by a brimstone blast must succeed on a Reflex save or catch on fire, taking 2d6 points of fire damage per round until the duration expires. Additionally, if more than one fifth of the target's max hit points are dealt in damage, the target must succeed on a will save, or become frightened. The fire damage (and fear effect, if any) persists for 1 round per five class levels you have. A creature burning in this way never takes more than 2d6 points of fire damage in a round, even if it has been hit by more than one brimstone blast.
