but your xp = your heart

Another challenge for challenge lovers is offered by the but your xp = your heart mod. Imagine that the more experienced you become, the more health you'll have in Minecraft. This is a difficult challenge because experience is quite hard to gain, and at first you'll have very few hearts. Right after entering the survival world, you'll have only half a heart. Each level gives 1 heart, so at level 100 you'll have a full 100 hearts.
