It would be neat if there was an item you could purchase for about 10 Crystal Energy that lasted for a day called a Heat Canister. As long as it's in your inventory, Heat you get doesn't upgrade your gear: it's stored inside it instead. You then sell the Heat Canister to vendors and they give you crowns for how much heat is inside it.
I don't think there should be any sort of cap: you just have a 24 hour limit on it obviously before you have to sell it and buy a new one.
Thoughts?
ooooo how about the timer starts when you activate it? i would love something like this especially if i have all my equipment at max
