You scour the magic from your target. Any spell cast on the target ends if it was cast with a spell slot of 3rd-level or lower. For spells using a spell slot of 4th-level or higher, make an ability check with a DC equal to 10 + the spell’s level for each one, ending the effect on a success.
You automatically end the effects of a spell on the target if the level of the spell slot used to cast it is equal to or less than the level of the spell slot used to cast dispel magic.
Leska’s Confiscating Dispel Magic. When you dispel a spell that was cast using a spell slot at least 2 levels lower than the one used for this spell, you can use your reaction to expend a spell slot of equal level to the dispelled spell and immediately cast it at a new target.
