WARNING

Even though "Held item" can be -1 to represent an empty slot, the client doesn't know how to render held item -1 on other players when they spawn in. As a result, this value must never be lower than 0! This only applies to if this packet is sent in isolation and not immediately followed up by a set equipment packet. Read up on proper usage of this packet on the relevant behavior page!
