How to Play Co-op for Sword of the Necromancer

How to Play Co-op

When you play the dungeon floor after the tutorial you will be able to find the Flask of Homunculus beside the Inventory chest, on the right side of the Altar below the stairs. If you have the flask on an active slot it will automatically be used when you enter the dungeon. If you have a second active controller attached to your console when you enter the dungeon the Flask of Homunculus will create a copy of you which can be used to play co-op. This will also unlock the Dwarf in the Flask achievement/trophy which requires you to use the Flask of Homunculus.
