Well, i do it with a bear as partner but i think it could be the same patron for any other class.
We put Odyn in a place near the entrance or near the throne and the tank wich is targeted for the spear runs in the opposite direction.
As a DK Blood you should use de WW if you have it, but if you dont (too long cd) keep running, ask for a shaman to put the totem who give speed movement or choose "Rune Tap" or "Spectral Deflection" to use as talents (or both [i make use of both of them]).
And you should try to stay near 100 - 80% of hp befor Odyn start casting the spear.
