Emergent gameplay is pretty cool.
Link can stay in the shadows cast by objects to prevent heat damage. By carrying the object with magnesis and staying in its shadow, it is possible to avoid heat damage without potions, clothes, or ice weapons.
This is tested to work with the Lynel Crusher, Lynel Bow, Boulder Breaker, and Iron Sledgehammer. Other metal objects may work if large enough. Shields are right out.
