Nodding briskly to Arthur and bowing to Amina, Keith yanked out his wand. He had to distract Amina while staying out of Arthur's way. "Expelliarmus!" Keith shouted, aiming for Amina. He saw Arthur contemptuously block Amina's curse and respond with his own, and he grinned. Now that the initial volleys were over, it was time to get creative. Whipping his wand towards the floor, he braced himself. "Expelliarmus!" This time the spell hit the floor below him, sending a small bit of dust and gravel flying free. He dodged left, then right, just to throw Amina off, and scooped up a handful of gravel before breaking into a run. He ducked again for good measure before leaping into the air a few feet in front of Amina.
Time seemed to slow.
Keith's hand tightened around the gravel before he let it fly at Amina'a face. It would not cause any damage per se, but it would distract Amina for a few crucial seconds - seconds Arthur could use. "Go Arthur!" He shouted as he hit the ground, trying to scamper away before Amina could regain focus.
