Artifacts which add to stats or skills if you keep them in inventory (make inventory mgmt more interesting, and get over the 'not enough skillpoints for rogues' type complaints).

Timed quests (or at least rewards which go down if you don't do the quest fast enough).
.. therefore ..
Some indications of game time (month, year, whatever) not just wallclock time.

More trainers (dodge, thieving skills)

More in-game dialogue hints (like 'you know you can steal with impunity while you are invisible, don't you' from the thief trainer, or 'watch out for the damn ghosts, coz they can curse you' from the crypt folks. or 'You need to get that disease seen to, because it won't wear off on its own', from anyone who notices you are diseased).

Yeh like the compass pendant that added 2 to Cartography... That should have just been a compass that added 2 to Cartography just by having it... good idea.

But items that are for the same bonus should only allow the highest bonus. So if you had two compasses, you would only get one bonus not both added together.

Could play it either way .. as long as the items don't stack. Assuming the item only gives you +1 to cartography (or dodge or whatever) you are not going to get many before you run out of inventory (even assuming there are a lot in the game to start with .. the items could even be uniques).
