In fact, this is an alternative to the phase dance skill, which allows you to make four moves as one move. But with the owl feathers skill, you can use sprint silently. It is easier to notice the player, and you need stamina. But the skill is not a one-time skill, but is used a certain number of moves after casting. A cross between camouflage and phase dance. Of course I'm comparing two skills from the stealth perspective.
