Monstercrafting can be trained by using the raw materials, required to make the monster, on a Empty monster box. This will create a box containing the monster and will provide the player with a sufficient amount of experience. The box can be sold in the Grand Exchange or be released. The monster can only be released from the box if the player is in the dungeon in their Player-owned house (only your Player-owned house). If a player dies to the monster then they will respawn outside the house without losing any items but the monster will disappear meaning no drops. If a group of players kill a crafted monster, then the only person who gets the drops is the player who released the monster.
