Wondrous Item, legendary

From the Astral Plane, this Magic Item allows the wearer's body to handle attuning to more Magic Items.

As an Action, you can touch the Astral Mox. Touching the Astral Mox grants you two additional attunement slots permanently. 

You can benefit from this effect only once. After the Astral Mox has this effect activated its power to grant attunement slots becomes dormant for 1 year.
