Aura of Suppression

Enervating energy radiates from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centred on you. Any spell targeting a creature, object or the area within the aura is displaced into the void, dispelling it. However, this diminishes the auras potency, costing charges according to the dispelled spell level. When the spell reaches 0 charges, roll a d6 (+ current charges), and on a 1, it vanishes. Otherwise, the aura returns to one charge.

The spell charges are equal to your spellcasting ability.
