Nothing more entertaining than a good ol' fashioned dragon spawn imo.
Unless your in a spot where the dragon won't stop flying and come down because theres no nearby "drop spot", instead you're left with an airborne pratt constantly breathing frost/fire.
Last night on Legendary this Frost Dragon really irritated me, when I used Dragonrend, it flew miles away from me and my follower, on foot it took ages to locate the dragon, and then guess what, it flies all the way back to the spot I orignally wanted to fight it at (Word Wall) which really annoyed me!
Was so glad when I hooked up with my 3 Blade recruits who were also at the spot chucking magic. We just gladly hammered it from all sides.
