Ring of the Warcaster

This silver ring is engraved with images of swirling magical spells.

While attuned to this ring, you gain a +1 bonus to spell attack rolls. In addition, this ring has 3 charges, if you miss a spell attack you may spend a charge to avoid spending a spell slot on the missed spell attack. Expended charges are regained after taking a long rest. If you expend the last charge, roll a d20. on a 1, the ring turns to bronze and no longer holds any charges.

Notes: Bonus: Spell Attacks, spellcaster, Buff, Combat
