Vayne took a step back, lowering his bow. Dust had just caught his arrow. Sure, he'd heard of and legends of heroes who could do such things, but to see it with your own eyes was completely different. To stop an arrow and block Silef's magic so quickly... Dust was fast, that was for sure. Still, Vayne couldn't help but wonder...
"Perhaps I'm the only one here with a chance of outspeeding him... And that's assuming he engages me head on, without retreat."
Vayne smirked at the thought. Dust didn't seem like the type of person who would retreat, especially from people who would seemingly pose no threat to him. He would give Silef and Ress'nok some more time. If they couldn't land a damaging hit, then he would step in and attempt it. He didn't want to reveal one of his secrets so soon, but if they were to earn Dust's approval, he might not have a choice, depending on the next few moments. That being decided, Vayne readied a second arrow in his bow. This time he aimed for one of the chinks in Dust's armor, an attack he couldn't ignore. Somewhat reluctantly, he turned towards the other two as he drew back the arrow.
"Silef, Ressnok!" He called out. "When I fire this arrow, take the opportunity to strike! It will be difficult for him to handle all three of us!"
As much as he disliked the idea, they would have to work as a team to stand a chance against Dust. He was used to working alone, but this was an exception. He would have to learn to trust these two if he was ever going to see her again. That much he knew.
Vayne made sure the two of them had heard him and understood before returning his gaze to Dust. He aimed for a chink in the chestpiece, the largest target and hardest to dodge. He waited only a moment, giving the other two a moment to prepare, before he loosed the arrow. It flew straight and true, right at Dust. He had no doubts that Dust would stop the attack, but he was relying on Silef and Ress'nok to do the real work for this part. And if they couldn't... he'd step in as well.
