Mob Mastery

Mob Mastery

Mob Mastery rewards killing mobs with sell price boosts and unlocks the managed spawner for each mob in a chain from sheep to shulker.

Mob Mastery is the combat track of Island Mastery. Each mob has its own element and gains 1 experience per kill. The elements form unlock chains that decide which mobs you can buy and place as managed spawners, and spawner Level upgrades need a minimum level in the mob's element.

Spawners: buying and placing the mob's spawner needs its element unlocked (Obtaining Spawners).
Spawner Level upgrades: levels II to X of a spawner need the mob's element at level 8, 15, 22, 30, 38, 46, 54, 62 and 70 (Spawner Upgrades).
Slayer robots: need Mobs Mastery level 5 to unlock and deploy (Mob Robot).
