To do this you have to be in forge with two players.

Spawn two armor locks and have one player pick up an armor lock. The other player turns into forge mode.

The player in forge mode presses X pointing at the armor lock. Then he goes to "delete all items".

Then the player with armor lock uses armor lock and at the same time the person in forge mode hits delete all items.

P.S you can still die by falling into water or being assasinated.
