"Covetous"@en . "Certain high-level monsters are covetous, in that they desire one of the unique items or your quest artifact. Some covetous monsters are able to steal the item they covet from your inventory. The quest artifacts of other roles are immune to this theft, as is yours if it is stashed in a bag. There is no defence against this theft for items in your main inventory; this is especially troublesome if your only source of magic resistance is your quest artifact. Covetous monsters cannot be tamed by any means. The Wizard and all quest nemeses cannot even be pacified."@en . . . .

There is no defence against this theft for items in your main inventory; this is especially troublesome if your only source of magic resistance is your quest artifact. Only quest nemeses and the Wizard of Yendor have stealing attacks.[citation needed] On one-twentieth of the hits from such an attack, the monster will look for one of the above items in your inventory; if it finds one it will steal it and, if capable, teleport away. The Wizard of Yendor is most notorious for this; if he casts Double Trouble, his double has a chance of carrying a cheap plastic imitation of the Amulet of Yendor which can be confused with the real amulet if it is stolen. Covetous monsters cannot be tamed by any means. The Wizard and all quest nemeses cannot even be pacified."@en .
