Block Boi is the perfect Magic Item if you want to play a fun game of Prop Hunt with your friends.
On use, Block Boi disguises you as the block you are standing on for a full minute. After use you will have to wait 15 seconds before you can use Block Boi again. You will have to choose your location precisely since your disguise wears off if you move a few blocks.
Block Boi can be obtained from Tech Chests.
