Azphelumbra.
I've worked with Stigma Stones for most of my life. I've never forgotten that Stigmas are the dignified souls and spirits of our ancestors.
They are a link to our past and our people. Please keep that in mind.
May you soar in Azphel's shadow.
I'm sorry to say I can't help you.
As I mentioned before, Stigma Stones are much more than simple Augmented items.
Please come back again when you are ready to use the Stigma Stone.
