Ways to remove cursed/noremove/nodrop items: 1. cast remove curse 2. find and use a "travellers holy symbol" 3. find one of several kinds of potion 4. change yourself to opposite alignment (so it zaps you and falls off) and, of course, 5. suicide. (be sure NOT to pick up the cursed item when you retrieve from your corpse.)
