Tempest, realizing what you were up to, targeted her next magic blast at the slabs in your possession. She succeeds in destroying one of the slabs in your grasp as you lift them into the air, but you quickly retask the freed hand to lifting the other slab, succeeding in launching it straight up into the air. She tries to blast it out of the air, but misjudges its trajectory and misses, allowing the slab to come right back down towards you. And just as it comes down, you give it the mighty foot with a spinning start, launching the chunk of debris straight towards her like a cannonball.
