Arcane Acceleration

You draw on volatile strands of time to accelerate your magic temporarily. For the duration, you cast Cantrips with a casting time of 1 action as a bonus action. Additionally, casting a spell as a bonus action does not prevent you from casting another spell of any level on your turn as an action. When you do cast a second spell on a turn as either an action or bonus action, there is a 5% chance the magic malfunctions, and the spell fails to cast (any slot or resouce required is still expended).
