I may be the only one playing this game, but that won't stop me being pleased about finding a Bronze Dragon Scale Mail from a Deep One (quest guardian, although not the last one - he dropped a naff armour of resist cold) on level 22

It's (-2) [30, +15] plus confusion resistance (though I already had that as a beastman) and breathe confusion every 450+d450 turns. I may have inadvertently lost the Elven Cloak from the Orc Camp quest, but I reckon that armour, a Short Bow of Velocity and the artifacts Metal Cap of Thengel (+Wis, Cha), Iathrond (shield) (+12, +13) [6, +17] (Improves searching, immune fear, resist poison and dark), the Phial of Galadriel and Barrukheled (axe) (2d6) (+13, +19) (+3 Con) (Deadly against orcs, trolls, giants and evil, see invisible) pretty well make up for it
Oh, and a Rod of Recall dead early too, which saves me learning the spell later
