Azor's Ring of Unbound Potential

This simple silver band, engraved with elvish runes, bears ancient arcane magics stolen from powers unknown to mortals.

Whenever you cast a 1st level spell or higher using a spell slot higher than the spell cost, you may expend a charge to cast the spell as if it were cast one level higher ex; casting a 1st level spell using a 2nd level spell slot would count as if it were cast at 3rd level.

Notes: Requires Attunement by a spellcaster
