How to Make a Bow-Kata Monk/Fighter?

[Misterwhisper]

I personally was just going to think of it as reinforcing it with Ki.
Like many Monk abilities use Ki 'the resource' but all of it uses Ki 'the concept' such as their ability to Slow Fall for example.

I was just going to file, "strengthening bow for melee strikes" as part of it.
Not augmented enough to count as magical (which needs 6 levels in Monk first) but enough that it wouldn't snap the first time you smacked someone.

If you are going to be using it in melee as a quarterstaff, depending on what race you pick, wood elf being a great choice, you will be proficient with a longbow anyway.

Flurry can be used even with a longbow normally.

Kensei is a pretty horrible subclass.

However you could always see if your dm will let you consider the bow a club when improvised as a melee weapon, take longbow and improvised longbow as a club or great club as your kensei weapons.
