Spellbreaker’s Axe

Weapon (greataxe), very rare (requires attunement)

You have a +1 bonus to attack and damage rolls made with this magical greataxe. Once per turn, when you hit a creature with an attack roll using this weapon, you can force the target to make a DC 15 Charisma saving throw. On a failure, it can’t cast spells other than cantrips and the magical properties of each non-artifact magic item it is carrying is suppressed until the end of its next turn.
