Ice creeps from your fingertip, filling the inside of the lock and jamming the door shut.

Ice spreads from your fingertips. In one round, you can cover one adjacent 5 ft square with a thin layer of ice. You can only spread ice about a foot from your touch. The ice spreads too slowly to trap creatures. This ice spreads over objects and surfaces, so it is difficult to shape or sculpt as you produce it.

Characters must spend 2 squares of movement to enter a square covered by ice, and the DC for Acrobatics checks increases by +5.

After one minute per caster level, the summoned ice disappears.
