Frost Driver

You send ice spikes along the ground towards a single target, making a Heavy attack that deals Frost Damage. This cannot hit a target higher than 5ft above the ground. On hit, the target is Slowed until the end of their next turn.  If the target is already Slowed, they instead become Rooted, making them unable to move until the end of their next turn.

Combo: When used after Icicle Nail or White Thunder hits, reduce the mana cost to 0.
