Ice Trap
Requires GTrigger, Key Timers 2; all included in the map.
Spell Description: Icicles pop out of the ground circling a targeted unit, and trapping everything inside. Any ground units trapped inside cannot get out, and no ground units can enter. This ability can be used to separate you from an army, and fight off a smaller number of enemy at a time. Deals damage per second to enemy ground units near the icicles.
