When brewing a Berserk Potion, add a candy to brew a Cloning Potion. This spawns a second copy of the player on top of the original and fights alongside the player. If the player uses a teleport spell while a clone is still alive, it will not teleport the clone. Enemies like the Octopus King will prioritise the player over clones. If the player dies when a clone is still alive, the quest will end as normal, regardless of whether the clone would have actually won.
