For your Braver Tree, with the amount of Skill Points you can get and the lv85 「Braver Combination」 Skill, you can take every 「Stance」 Skill (except the 「Critical」 Skills, which you don't need thanks to 「Braver Combination」), and every Katana and Bow specific Skill, and still have Skill Points left over to put into other miscellaneous Skills.
One of the best subclasses for a Katana-only or Hybrid Braver is Phantom, and its tree is pretty simple: just take everything that isn't part of the 「Phantom Marker」 line.
Your basic Tree would look something like this: https://bit.ly/3i6Dp2E
You want to get a full DEX mag for this build because the Skills 「Braver Mag」 and 「Phantom Mag」 stack together and will convert that 200 DEX into 400 MEL-Pwr and 400 RNG-Pwr.
You are going to want to create the 「Critical Strike (R)」Composite Ring so you can get +20% Crit Rate and +3% Crit Damage with both Katana and Bow, but to do so, you need to level a 「Critical Strike: Melee (R)」, 「Critical Strike: Ranged (R)」, and 「Critical Strike: Technique (R)」 to +20, so that can take a while. As for your class-specific Ring, you can get 「Brave Power (L)」 which is a Composite Ring of 「Katana Combat Hitcount Up (L)」 (reduces the number of hits needed to power up your finisher during 「Katana Combat」) and 「Bow Homing (L)」 (makes normal Bow attacks home-in on enemies).
