Whoever designed the encounter table for the Lair of the Father is a sadistic asshole. Dark Sages are ungodly powerful, and have an insanely high attack speed, and Moonmaidens are just evil bitches. They're not even worth fighting, since they give you CRAP experience.
Someone please find this guy and throw a brick through his window. Then while he's focusing on fixing that one, break all the others.
