Chiller was a Common trap in Battle Royale. It was a trap that could be placed on floors, walls, or ceiling that applies icy feet to players, causing them to slide around with low friction. Emoting, bandaging, shield potion usage and other movement cancellable actions would be used while affected by Chillers. It dropped in stacks of 3 and could be found in Supply Drops, Vending Machines, Supply Llamas, and Chests.
The Chiller was added to the Vault in Patch 7.00 making it available in Playground and Creative. The Chiller was vaulted because it wasn't being used too much and it was a very futile trap.
