And going back to one of those dark memories from oAD&D, might I trouble you about the assassin?
It's one of those things that I've always seen debate on amongst 1E people: does the assassination ability work against any old monster/opponent the assassin happens to surprise in a dungeon or elsewhere, or is it only usable against the poor innocent soul that the assassin has been hired to kill?
Or is it somewhere in between? Something that requires planning, or something that can be done on the spur of the moment?
Cheers!
