When Sal stumbled, Banru swiftly let go of him and pulled his arm free of the spell before it ended, remembering full well what could happen if you weren't fast enough. He had seen people lose hands, fingers, even arms if they weren't careful. He met Sal's eyes for a brief moment as he spoke, then, knowing what he was about to do from his slow motions, ducked. The dirk embedded itself in a tree behind him with a dull thunk.
"Straightforward and predictable." He replied, his voice scarcely more than a low growl. He scratched out a quick symbol in the air next to him, pausing for a short moment so that Sal would have enough time to react before activating it. With a low whistle, a blade of wind sliced toward his teammate. It was a weak spell, and even if by some miracle Sal didn't manage to get out of it's path in time, it would be about as painful as a strong gust of wind. It was more for show than anything.
