I haven't seen information on this since the CS days, and the chat about the new Ithzir Champions bellowing people to death got me thinking: can we have a little insight into what factors affect the offense and defense of War Cries?

My assumptions:

Offense: INF Bonus
Defense: Yertie's Yowlp
Both: War Cry ranks, level difference

Back when War Cries used a CS system, CvA was part of the calculation, and thus heavy armor provided a significant defense against War Cries. Is that still the case? I'm not sure if I should be advising newbies to go yell at boars and other beasts for that juicy +25 CvA. (It's, uh, been a while since my Warrior mastered.)

Do Lichbane or the anti-fear spells/abilities provide any defense? INF/DIS bonus? Any skills involved?

Thanks!
