NPC Spawn Issue: X'Ta Tempi/Tompi/Timpi (Neriak)

[Nocte]

These three sisters are along the top of the top of the wall as you enter Neriak. They should have the Robe of Enshroudment in their loot tables, and Allakhazam posts from 2001 make it sound like they should always drop the robe.

If I'm reading too much into the lucrative drop rate, can someone look into their loot tables and see if there's even a chance that they drop this item? I've killed 4 of them as of this post and they didn't drop anything but coin.

Thanks.
