Renamed items and drops from mummy lords

I keep meaning to mention, I do really enjoy the more flavory names of items that have gone in, and the individual appearances. "Amulet of *'s Skin" is just better than "Amulet of Natural Armor +*" But around the same time I noticed this change, it seemed like certain stones and crystals just stopped dropping from the mummy lords... items that are required for various dwarfy quests and modes of item enhancement, some of which can be gotten elsewhere but many of which I've never seen drop anywhere else, yet. Certain rings seem to have stopped dropping, too. Was this intentional?

There a couple of items that seem to have disappeared from loot drops/merchant inventories over the last few months. Dave and I were talking about rings of clear thought ourselves last night.

The stones should remain the same as before. Just random chance that they're not dropping for you.

rings of clear thought will be returning in the near future, along with addition stat boosting items for the other stats. The only reason I took them out is because none of the other stats have items that fit more than one slot for stacking of the bonuses (ok, so gauntlets of ogre power are there too, but they don't go to +6 like the rings). When the rings return, there will also be additional items for boosting the other 5 stats.
