D&D4e question here.
Does the Ranger powers with the Beast keyword work for mounts and other animal companions besides the companion you pick from your Beast Master class feature? Just wondering because I noticed that good ol' Drizzet is a Two-Blade ranger but still has Beast powers. He also has Guen (Flavored Golden Lion) in his item inventory.
So for example if I used Circling Strike and I had, say, a wyvern mount, would the wyvern be able to shift 1?
