A frenzied undead othmir

Strategy
This is probably the best representation of zombie tactics in the game. Even though these come in groups of 2 or 3, they act like the zombies we've come to love in the movies. In this area it appears that the other groups of zombie Othmirs are attracted by commotion, so even if you think you're out of aggro range, the other groups start moving in.

They aren't fast but roamers, other groups and the ^ heroics will be attracted by your engagement. Before you know it you'll be overwhelmed. It's best to pull each group up onto a surrounding rock outcropping to fight. Rinse, wring, repeat.
