Antimagic Touch

You reach out and touch one creature that's within range of you to prevent it from using magic.  The target must succeed on a Wisdom Saving Throw or it will lose its 1st level Spell Casting Ability for the duration.  At the start of each of it's turns,  the target can make another Wisdom saving throw.  On a success, the spell ends on the target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the target will lose its respective level Spell Casting Ability as well as all levels below it.
