After reaching the End biome, the ability to prestige becomes available by tapping the second page of the biome selection screen. Prestiging converts all of your blocks to 3 ender pearls, and relocks all of the biomes, except Plains, and leaves everything else unaffected. In addition, upgrades to pickaxes become unlocked. The max prestige level is 999.
In order to prestige, you must have the following:
- Be currently in the End
- The Furnace is not running
- Have a certain amount of Picks
- Have the end stone pickaxe
