Resist Fire

 is a positive Status Effect which makes Fire do 3/5 the usual damage (Fire will deal 6 damage instead of 10). This status affect is currently only available through wearable items.

Function
Every hit will reduce the remaining durability of the item, so essentially health is being partially traded for durability. Once durability of the equipped item reaches zero, the item is destroyed and the status effect removed. The status effect is of course also removed if the item is unequipped or dropped.
