Level 7-6 at 1050ft. The monster part was an ant pit. The object part... was a scroll of acquirement. And what I got from it was this lovely katana...

the Katana 'Luiarim' (3d5) (-18,-9) {cursed}
     Conjured forth by magic at 1050 feet (level 21).

     It occasionally makes a loud noise.
     It occasionally summons a demon.
     It makes it hard to hit anything.
     Cannot be harmed by acid.

Look on the bright side: now you won't find that thing later.

Wow, -18 and on top of that it makes it hard to hit anything. ^^

Your next challenge run should be to win a melee character wielding that, without enchanting it or removing any of the curses
