Still using him for Universal Villain, my best score 360k+. Open with 4 then go to 5 then 3 kiting, spam all skill from behind the frostbeast, always use 3 and 5 whenever you can use them.

The old way to use him pre-ragnarok was 3 (which if you havent yet, max the skill, it guards 8 hits), 5, then run around, using 4/2/1 only when it is safe for some extra DPS.
You can always hit 3 for the shield, summon clones with 5, then run around. It shouldnt be too unsafe to throw in his other skills though, if you have the shield up.
