Aeon

You can fit one aeon stone or spell gem into this weapon with a single Interact action. While you possess the weapon with an aeon stone in its indentation, you gain all the benefits of the aeon stone as if it were orbiting your head. While the weapon has a spell gem attached, you gain a number of bonus battery charges equal to the spell gem 's item level × 5. These charges regenerate during your daily preparations. In addition, you can use the spell gem while wielding the weapon, though using the gem in this manner still destroys it.
