The Cold Gun is a weapon used by Captain Cold.
Holding the Cold Gun sprays an unlimited beam of ice, creating an ice layer on anything that it touches.
The beam has a limited range of about 35 blocks (depending on direction), and the ice layers will eventually melt away.
When used on mobs, the mobs will take damage.
- NOTE you must be wearing the specified suit to use, in this case, Captain Cold
The Cold Gun can be crafted with three iron ingots, one normal ice block, one button, and one gun base.
