steelfleece is like an impossible mob to fight pre 65+ since it hits for 350-400 and if you cause to much aggro it'll simply summon you and start hitting you
if you pass by or decide to attack it and run your dead, it'll summon you untill your dead
but the other rams really aren't that tough
I've seen a monk lvl 30ish solo one of them by useing 100 fists pretty damn easily
