Ring of the Evoker

While wearing this ring you can use an action to expend 1 of its 10 charges to cast magic missile, thunderwave, or burning hands from it using your spell save DC.

If you are wearing the ring and fail a saving throw against an evocation spell that targets only you, you can turn your failed save into a successful one. You can't use this property of the ring again until the next dawn. If you succeed on a save against an evocation spell that targets only you, with or without the ring's intervention, you can use your reaction to expend 1 charge from the ring and turn the spell back on its caster as if you had cast the spell.

The ring regains 1d8 + 2 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, it becomes a nonmagical ring.
