After unlocking the Earth Gift Shrine (by relighting the Earth Crystal), head there to find an item that increases your life permanently by five (it’s in the desert section of the Shrine). If you continue on in the shrine and lose to one of the four bosses within, it will send you back to the beginning of the Shrine, but you’ll still have that item. What’s more, you can get the item again when you proceed through the Shrine once more. You can repeat this process over and over again to get the item as many times as you want!
