Glaciate

You blow a wind of freezing cold air at a creature in range. Make a ranged attack roll, dealing 1d10 + MOVE ice damage on a hit. On a hit, reduce the target's speed by 5 feet. A target reduced to a speed of 0 in this manner becomes frozen. The target may use an action at any time (before becoming frozen) to warm its body, resetting its speed.

At Higher Levels: The damage dice roll for this move changes to 2d8 at level 5, 5d4 at level 10, and 4d8 at level 17.
