Would it be possible to give Harm Horde a look? I can hit 4 mobs twice for a total of 8 hits and still only advance one mind state, where as sometimes I can get 2 mind states with one cast of Fists of Faenella. Conversely I can get 3 mind states off stunning 3 mobs with Phelim's Sanction. I think considering the undead restriction Harm Horde could stand to have its learning increased.
