The presence of Chillwater is indicated on a machine by Freeze Canisters. Chillwater can be harvested from a machine by using Harvest Arrows to remove the containers, using a Heavy Melee Spear to knock them off, or dealing enough damage to the Chillwater to knock it off of the Machine. Chillwater can also be shot at with Freeze Arrows or Freeze Bombs to trigger an elemental explosion that will freeze everything and everyone in the explosion radius. All things frozen will take more damage from all sources.
