Wall Blast

You can create a wall of your element which anyone who walks through takes damage from.

EXP Cost: 6 EXP

Benefit(s): As a full-round action you can transform your blast into a wall instead of a single target effect. The length of the wall is equal to 4 squares per point of Constitution you have, and the wall can be created anywhere within 12 squares of you. This lasts 2 rounds per point of Constitution you have. Those who walk through the wall take damage with no attack roll made against them, and those within 1 square of the wall have an attack roll made against their Reflex Defense (dealing 1/2 damage on a failed attack).
