[Odann]

He has VERY high MR. Near impossible to slow.

Best way to attempt to slow him would be to kill his wolves prior to popping him and then send your pet in to try and tank for a few seconds while you try to get a Malo off. IF you can get the Malo to land and the subsequent slow, then you could solo him.

Outside of that scenario he is, at best, duo-able.

Most effective duo is to have a high level melee tank him while you dot and torpor. Or have a Bard/Necro kite him.
