You open a gate through Hell to connect points on the battlefield. Your allies can pass through it unharmed, but your foes cannot.

Minor Action      Ranged 10

Target: Two unoccupied squares

Effect: You create a dimensional rift between the two target squares that lasts until the end of your next turn. Any creature that enters one of the target squares can move to the other target square as if it were adjacent to that square. A creature cannot pass through the rift if either square is occupied by another creature. Each enemy that moves from one gate square to the other takes 1d10 + your Constitution modifier fire damage.

Sustain Minor: The gates persist.
