Not sure if these are good equipments for Master Strategist. I equipped her with Takenomata Kaneko, Snow Fox Mask, Three Character Classic and Armillary Sphere. Sorry, I don't get it. Are you saying save it a month or more and not the next Platinum Priest Event?
Oh btw, what's a good inherited unit for Master Strategist? Also, since Master Strategist targets all... Will Skill of Naraku be OP?
