To sign, hold right click with the contract in your MAINHAND (it doesnt work in offhand), when the soul contract changes textures it has been signed.
Consume a signed contract to teleport the player who signed it (indicated by it's item name) while its in your MAINHAND (will not work in offhand, again) to teleport the player to you, then immediatly kill them.
Using an unsigned or signed contract will consume the whole stack, so don't stack them.
YOU CANNOT RENAME THE CONTRACTS OR THEY WILL BREAK.
