Need help with katana combo & build

hi im still new to this katana class and i want to know what kind of combo that can dish out the most dmg?
and anyone know what kind of katana build that focus on critical dmg rather than critical rate?.

 

1) Highly depends if you wanna use Tenryu, Garyou or both. For Tenryu i don't use any combo at all. For Garyou you can just check some of the builds here which have proper combos.
2) Thats more a question of equipment than anything else. Even though you can pick up meikou which increases your crit chance temporary.

 

1 mp combo for tenryu starter: pulse blade, war cry (save), flash blast (consec), kairiki ranshin (consec), tenryu

After starter use magadachi (3 mp) to increase tenryu duration

After using starter and magadachi keep spamming tenryu, and then use the starter again (to get kairiki buff), after that use 2 mp combo for garyou: issen, zantei (save), garyou (smite), reflex/flash blast (consec)
