Requirements for Acuman on SOM

[Greeny]

I want to put acuman on my SOM but never done an A grade weapon. I have the SOM and crystal. Do i need anything else and where do i do it?

Besides the stage 12 crystal (blue? not sure) you need Gemstone A. 157? 143? Forgot about it. Take both and your weapon to the Blacksmith of mammon.

Player stores or Merchant of Mammon. Mammon takes 30k AA iirc.
