Revs are low risk, low reward. I've killed two rev orks in a row using only a whip, salve amulet (e) and no food. I attended one of these rev hunting events yesterday, and it was pretty unsuccessful. Totally unorganized, and there were almost no revenants to be found. Of the three revs I saw, I coudn't even attack one, they were all low leveled vampires, goblins, etc. Lame...
