21 Things You Can Only Get with Commands in Minecraft 1.21! 

Minecraft has a limited number of items and mobs. Yes, that number is very VERY high but after multiple years of playing the game, you start to get used to it all. However, the items and mobs we’ll go over today are different. Not only can you obtain them only using commands, but a large majority of them can be customized to your liking. From edible maces, to multishot 12 crossbows, to fists that can uppercut mobs into space - these are 21 minecraft things you can only obtain with commands.
