Your swarm expands in a burst of fury. The sky momentarily blackens as you partition yourself in two, forming a living wall.

Daily   ✦     Beast Form, Implement, Primal
Standard Action      Area wall 8 within 10 squares

Effect: You split part of your swarm into a living wall. The wall can be up to 5 squares high and lasts until the end of your next turn. The wall provides cover to those on the other side and counts as difficult terrain. Any creature that enters the wall takes 1d12 damage. A creature can take this damage only once per turn. Any creature that starts its turn in the wall takes 2d6 damage. Any creature that enters the wall or starts its turn there is subject to the gripping swarm attack power.

Sustain Move: The wall persists.
