Brimstone Blast

Brimstone Blast(CArc p132)
<Invocation(eldritch essence)[fire]>
Description: The invoker’s Eldritch Blast does Fire damage (instead of Untyped damage). In addition, any creature struck by the attack Catch Fire(RefNeg). Catching fire this way lasts for up to 1 round per 5 Warlock levels and does 2d6 Fire damage each round. Putting out the fire early is a Full Round Action.
Being struck by multiple Brimstone Blasts does not increase the burning damage per round, but does reset its duration.
Effective Spell Level: 3rd.
