GetEquippedItemBySlot(Player, slot_id)
GetEquippedItemByID(Player, item_id)
GetItemByID(Player, item_id, count, include_bank 0 = false 1 = true)
These are used exactly how they look, just pass a player pointer for Player, and it checks that player for item pointers using the given values, the function then returns a pointer to that item.
