Eudemons only work when they are embedded into awakened weapons.

How to embed

The awakened weapons can be made sockets at Arms Dealers.

After making eudemon sockets, you can embed eudemons into the awakened weapons.

The embedment is conducted in the Magic Cube. Put your awakened weapons in the Sun slot and an Eudemon in the Moon slot, and you’re sure to succeed in composing. The Eudemon will leave your bag and “inhabit” the weapon.

The awakened weapon must have enough sockets; otherwise the system will say “Your awakened weapon doesn’t have enough sockets.”

Put the weapon and Eudemons into Magic Cube in the appropriate slots.

Click Run, then the Eudemon is embedded into the weapon.

After embedment eudemons are in the default state of dormancy on their arrival to the weapon, in which case, they can’t come into effect.

To activate eudemons you need to left-click the icon and clicl the “activate” button on the bottom of eudemon panel.

After activation the eudemon icon will turn to bright.
