Just realised that I have enough spare gp on my sheet to get a lesser truedeath weapon crystal (grants attacks the ghost touch quality). I kinda overlooked that hole in my offensive capabilities since the Ghost Hunter feat grants it at lv11.
Would it be okay to add it to my sheet now? If not, can I add it after this battle? EDIT: Since the thing we're fighting isn't incorporeal, I'm going to assume it's okay.
