I DIDN'T SPOIL ANYTHING. Minecraft: Ultra Hardcore is a gamemode originally created by Guude and the group Mindcrack. In this UHC, we play on the 1.9 new update. Health does not automatically regenerate, so players must use a golden apple, golden head, or instant health potion. In addition, smelting is instant but will still require smelting materials + a furnace. Golden heads obtained from your opponents can be combined into an even more powerful head. Participants:.
