What you need:

you and a friend

a bed

a boat

a sword (if you wanna kill quicker)

it to be night time

what to do step 1:

place the bed and boat at the side of eachother


step 2:

get in the boat



step 3:

get in the bed and get the other person to destroy the bed


step 4:

you will apear in your boat, get out and get the other person to hit you once


step 5: on the other guys screen you will be floating over the boat, get him to hit you once (this will make you invinsible


you will be able to walk around as your normal body still is in the boat

when you press b your normal body will drop items

you cant see your normal body

you cant open doors or chests or place blocks or remove them but you can kill so do it on hard to rank up fast in leaderboards


hope i helped
