Uncommon sorcerer rune

[drigore]

I have one more teaching left of the shien'tyr-darkling rune. It is a third tier rune like the Abyran'sa. It's Shien'tyr, shien, darkling. I have 92 ranks in demonology and have failed it inside a summoning chamber. The odds of that are stupidly low, but it happened.

Anyway, I'm just looking for a general idea IF I was to sell this. Thanks in advance.

Darklings don't really provide a useful function like imps, abyran'sa or arashan unfortunately. I would say probably 2-3m just for the rarity.

I was offered 5 mil for an arashan teaching, if that helps any.

edit: darklings do have the best mana capacity
