Hello, i have some question about Braver bow and katana?

Hi there.

I'm wonder which Braver Katana or Bow is good for starter and what different between them

and also in this Video https://www.youtube.com/watch?v=qvfJ7OlEIEQ i really like that movement, can i do that at early lv?

Thanks

Short answer; no, this is absolutely not possible at low level, it relies heavily on certain skills, affixes and how your skill points are spent (also, as this is the JP version, there are skills/affixes/techniques that are not present in our current version)

If you want to go easy mode, use katana and spam Morning Mistreaver.
