Zeronium

Zeronium is a liquid found in the Underground Snow once three War Mode mechanical bosses have been defeated. It is found in sealed pockets where snow and ice was before. Being even remotely close to it gives you Chilled, and standing in it gives you Frostburn. You cannot pick it up with a bucket or pump it, you must use a Zeronium Canister to pick it up. Because this picks up Zeronium in a 3x3 area and puts it down like that as well, infinite zeronium hacks are not possible. It is the basis for most midtier War Mode weapons and armor.
