Version: 1.11.2 What I Want: I want spawners to randomly appear in certain biomes. The config needs to have this concept: Spanwer Type: Activated: true/false Biome: Spawn Chance: The spawners will only randomly be placed on the map ONCE per reset. Iron Golem spawners will be in villages, nether-mobs will be found in the nether, and endermen spawners will be placed randomly in the void of the end, so players must find them. Spawners can only be picked up with silk touch.
