Isek realized he couldn't stop running in time, so he sends out his chains behind him in order to launch himself backwards out of reach. He knew who Ander was even before joining Fairy Tail. Bound Fenrir had been a Dark Guild, and they'd faced or heard of most mage hunters in the area. The main thing would be keeping Ander from touching him or anything made from his magic.
Isek grinned. Good thing he'd never made the mistake of relying entirely on direct attacks. "Chain Magic: Collision Field!" Isek redirects his chains to ring the area, hurling huge chunks of debris at Ander from all sides. Even if Ander dodged or tanked the nonmagical material, it would set up his follow-up attack since any deflected or dodged debris would be bounced back by the chains. The speed would increase with each redirect and as the debris got broken further it would get harder and harder to dodge. If Ander didn't dodge or deflect he'd get pummeled and if he did he'd create a shrapnel cloud with him in the center.
