Using an Ice Crystal creates a frost breath, identical to the one made by Frostmaws, continually dealing 1 () damage to enemies in a 45° cone in front of the user and gradually slowing enemies hit more and more. Enemies that are hit enough are applied Frozen for 2.5 seconds, preventing them from doing anything.
The Ice Crystal quickly loses its durability while in use and will stop its effect when it is fully depleted. When not in use, it replenishes at a rate of 1 durability per tick, allowing it to fully regenerate in 30 seconds. Unbreaking can be applied to the Crystal to make it use its durability slower, allowing it to be used for longer.
