Disrupt Magic

You break a creature's link to their magical reserves.

Choose a target within range - if they are able to cast spells by expending spell slots, they must make a Charisma saving throw. On a failure, they lose a number of spell slots equivalent to half your spellcasting ability modifier, rounding up (minimum one, target's choice). If a creature targeted by this spell casts spells innately instead of by expending spell slots, and it fails it's saving throw, it cannot cast those spells for a number of minutes equivalent to your spellcasting ability modifier (minimum one minute). If the target has spell slots of a level higher than you can cast, those spell slots are unaffected.

If a creature targeted by this spell cannot cast spells, then the spell instead fails and the spell slot used in its casting is wasted.

At Higher Levels. If you cast this spell using a spell slot of 7th or higher, the level of spell slots you can affect is equivalent to the level of spell slot used or below.
