What are they worth?

[Manhart]

What is a Poison And Bone skiller worth in runes? (Clean sks)

[Taurean]

I haven't played for a while, but think they are quite valuable, i'd try to get Mal for each.

There should be a lot of high runes around now, there is also a ladder reset coming up. You could try to get an Ist for a beginning even.
