Another rune finding option is to run the chests of Lower Kurast. It helps if you have teleport, as you can blast through without even fighting anyone. Do it on /players 8 and you can get some decent runes.
Monsters don't have an Ilvl (item lvl). It's better if you don't use these abbreviations when you're not sure what they mean.
The countess has a different kind of drop, because she has her own Treasureclass, which is divided into an item drop (which can drop runes too, and is the only way you can get Gul or Lo from her) and a rune drop which goes up to Ist.
