Requires resourcepack.
Makes the whole world one big trial chambers. Also adds new trial chambers in nether and end with custom loot in vaults.
May lag when generating new chunks.
In the normal world, there is a 1 percent chance of finding a room with an Ender portal. The Eye of Ender doesnt find the portal.
The end portal cannot be found with the eye of ender. At 1 percent, the trial chamber will contain the end portal room.
