User blog comment:Dtx3D/Possibilty of Swords second upgrade? (極)/@comment-26117386-20150308101656/@comment-26012602-20150308130836

do you mean blueprint? yeah i think it's possible to use  some specific item to upgrade your swordboys if they have kai-ni like feature like KC.

well,i think people also start to lose interest in this game like last week tourabu got #7 in dmm netgame ranking but right now it went up to #2, i think rather than server they should add event like KC, i hope these two new sword become a event reward, well the game start to quite boring when you've already cleared all the map or they could implement extra operation map like KC that reset every month (you got medal to trade for blueprint)
