Merlin could feel the grainy scales rolling around in-between his fingers, and once he felt like he had enough, he charged forward at one of the orcs.
The orc was quick to notice something wasn't right, as Merlin wasn't being subtle with his movement at all. But fortunately for him, he didn't need the stealth to complete his plan, it was just more convenient if the four orcs didn't group up on him right away.
The orcs had started spreading out as they intended to circle around where the group of rangers were hiding, this worked in Merlin's favour.
Once he was almost face to face with one of the orcs, he threw a pinch of mothflower scales at its face, he made sure not to throw all of it, as he still had three more orcs to hit.
