where do i get high rune beside countess

yah i did alot of countess in hell but i didn't get high runes only el or nef rune i get anyone tell me what other place you can find high runes

Hellforge has possibilty to drop good runes.

thanx for info

Do rushes for people and let them give you their hellforge, good way to get runes.

if you are on ladder i believe that you can use the cube to keep making the next highest rune
