My Gandayah has just hit Chindi with basic attack and I got message "It is very effecient" or something like that. Chindi resists Slash and Pierce but is weak to Impact so I guess Gandayah used Impact base attack. Yet it is not visible anywhere in-game. Is Impact base type for all demons? If not, I suggest to display the type somewhere in description.
Another suggestion is to display spell range for ranged spells somewhere. It is unpleasant surprise when enemy has Frost Ring and you don't know if it can cast it at you or not because you have never casted the spell yet.
