I have build katana before, but still use garyou's main skill. now i change it with tenryu. this is more effective than having to spam 10x as much skill. although the final damage of garyou is greater, but there is a process that I do not really like. sorry for the weapon that I have not had time to upgrade, as well as the refinenya are still normal. I hope you understand. Have fun 🙂
