Core skin 20/20 would go for around 25-30k, but the crystallized skin is quite a bit more rare (and popular). I'm not sure I've ever seen one for sale.
I'd shoot for around 60-70k, but wait for more opinions.
Are the casting and recharge both in gold? Or is it really just a non-inscription version with the white 20% halves skill recharge for all? If it actually says "20% Halves Skill Recharge Earth Magic" and is actually "old school" then it is worth much more.
TY for the replies
Its the white 20% HSR for all and then gold inherent HCT 20% Earth and then slots for staffhead and staff wrapping.
I might put it in high end and see what happens.
