The Wraith Bone Hammer and Ruined Scale should be dropping, but not the other CoM loot or spells. Nor should he be dropping the Tainted Shield of Blessed Faith. I have been busy IRL lately, so I don't know if this has been changed.

It's possible that he shouldn't be dropping any Ruined Scale besides the chest piece, too.
