You may attach or detach this charm to a focus as a bonus action. While a focus has this charm, you have a +1 bonus to your Save DC.

This charm can be combined with the +1 Spell (Attack) Charm in order to equip both at the same time (simply equip both charms on DNDBeyond). You can only equip one charm on your focus at a time.

Notes: Bonus: Spell Save DC
