BTW, I'm sorry if I'm being dense, but how do they work together? I suppose the idea is to make the enemy cower with imperious command and after that charge to overwrite the duration of the cowering condition to 1 minute, as per Dreathful Wrath effect, but it still needs 2 rounds (because using intimidate doesn't activate the fear aura granted from Dreadful Wrath) and two failed checks...
The idea was something along the lines of
1) Charge in, activate Dreadful Wrath, scare some newbs.
2) Intimidating Strike a guy, simultaneously activating Never Outnumbered, Imperious Command, Cunning Insight (to shore up the attack roll), and Cunning Knowledge (for even more bonus to Intimidate). Now if I hit I make a demoralize check against everyone within 10ft. Any creature who fails Cowers for 1 round and because of fear stacking, any creatures who failed against Dreadful Wrath in the round before Cower for 1 full minute.
Maybe I misinterpreted the way he intended the nerf to work, but if it still works against multiple enemies then my above strategy is still credible.
