Mortal Chill

 is a Tier 5 Tank that upgrades from Chillbrid at level 60.

The looks identical to Chillbrid, but its Hybrid spawner on the back gains a small chill indicator like the front barrel.

Technical
The Hybrid spawner spawns the usual maximum of 3 uncontrollable drones, but unlike other Hybrids these drones inflict chill.
