This mod was disabled the health regeneration in difficulty ?normal’ and ?hard’ to make Minecraft a little bit more realistic and more difficult. The only way to get back your hearts is to use a golden apple or health potions. But don’t matter if you are going to die, you’ll just respawn at your latest spawnpoint. Your world won’t be deleted like in Minecraft Hardcore Mode! Or you change your difficulty level to ?easy’ or ?peaceful’ to disable my mod and reactivate the health regeneration.
