I tried to enchant a Trepwood helm on an krong anvil (the second anvil use in the current characters life) It told me that Krong wa spleased, yet the Item did not get any bonuses. Is this WAD (workign as designed) or a bug?
I got the same bug with a Plague Doctor's Mask. I've tried enchanting other items and the anvil works, but not with this one. If it helps, the anvil has been recharged the Ancient Kronian Ritual.
I've had one instance of finding a Witch Doctor's Mask (unmodified as far as I could tell) in the artifact slot in one of those rooms where picking up the artifact summons guards. I used This Belongs in a Museum on it, and it vanished without giving me any XP. Incidentally, I've also had an instance of Krong cursing an item and giving it blessing effects (i.e. bonus positive stats, instead of negative ones). I was wondering if Krong and Xom had been having drinks together, and the wrong one came back.
Is this an instance of an artifact not having an artifact quality rating? Doesn't something similar happen with Mossy Shield and Pancho With No Name (when placed on an anvil) going back to 1.0.6? I remember getting really frustrated with a Mossy Shield once.
