Fire proof and heat resistance are two separate things. You wear Fireproof to not be light on fire because of severe heat. Heat resistance is to not die slowly by sun.I bought both sets after scouring the map for the respective cities. Will the fire proof clothing help in the gerudo desert heat or is there a different set of clothes for that too? I just wasnt sure if fire proof is different from heat resistance or its the same thing.
I have yet to really accomplish anything since this game got leaked. I've just been having fun exploring this world, uncovering the whole map and completing shrines. Maybe tomorrow I'll take a crack at the temples.
