Bane Ring

The Ring has 3 charges, it regains 1d4 - 2 (minimum of 1) charges at dawn. While attuned to it, you can use your Bonus Action to expend 1 charge to cast 1st-level Bane. The Spell Save DC is 13. Using this ability to cast Bane still counts as casting a leveled spell and still requires concentration as usual.

Notes: Bard or Cleric
