Each Minion has 3 levels with each level working faster than the last.
To level up, access the Minion’s menu. Place it down and right click on the Minion. There you can level it up with GPs. For the Slayer and Miner Minions, you can also collect the XP they have stored from this menu.
If you choose, you can pair your minion to a chest anywhere on your island! This means all its loot is placed inside a chest that you can access as you work.
Choose to pair multiple Minions to a single chest so all their wood, food, ores and mob drops etc can be collected into one point OR select different storage chests for all of them.
Also choose to pair Minions to Chunk Hoppers (See Chunk Hoppers) making the most of their special abilities such as item filtering or autosmelting.
If you want, you can rotate Minions in all 4 cardinal directions, can change its skin and can give it a new name. It will also show you how much work it has done for you.
