Timewarp Fireball

You cast a Fireball into a temporal pocket. Before the end of your next turn, you may spend a Bonus Action to open an exit portal at a point you can see within 40 meters. The Fireball detonates at the portal's exit point - all creatures within 3 meters must succeed on an AGI Save against your INT + FCS Bonus. On a fail they take 3d8 + INT Bonus Force(0) damage and gain Fire(2). On a success damage and Fire Rating are halved. Only the initial cast can be Counterspelled or Dispelled - the emerging Fireball cannot.
