Much good did writing the buff thread do me
You got it right, I forgot BE was not self buff.
While we're at it, I find it strange the RoS kills heavily armored units such as Ctis city guards and also kills mages equipped with armor and helmet. I've even scripted poor marshmasters to cast mossbody all to no avail. So far the only protection from RoS I've found are BE and mistform and to a lesser extent luck and twist fate.
