The Frost Crystal is a more developed Frost Tower. Available at tier 2, the Frost Crystal is relatively weak compared to the Cannon Tower, which bears the same power cost and needs only one of its two orbs to be frost. However, the Frost Crystal, unlike the Cannon Tower, is able to attack both air and ground units. Also, it's biggest advantage is its special ability, allowing it to freeze up to 4 units in the target area for 10 seconds, with the maximum number of targets frozen increasing to 5 and 6 at Uprgrades I and II, respectively.
- Every 2 seconds, tower hurls an icy shard that deals 72 damage to enemies in a 5m radius around its target, up to 110 in total.
- Power: 0
- Freezes up to 4 units in target area for 10 seconds. After freeze wears off,targets are immune against Freeze for a while. Reusable every 30 seconds.
