Goldjaw is an item that allows players to eat Gold for health. Every piece of gold picked up heals one health, so for example a gold coin will health one health and other treasure will heal five. This can be useful for restoring vitality, but also means that players will be unable to accumulate gold. Due to the nature of this item, it may not be the best option as gold is needed to buy items from shops such as Goblin Wares, to pray at an Altar of the Ancient, to use a Potion Cabinet and to complete certain achievements. If you have the Curse of Midas, however, this may be a viable option.
