How to Make a Bow-Kata Monk/Fighter?

[Sorinth]

Awww but I even went through the trouble of finding the bow equivalent to Kensei, Yusei, 弓聖.
Kensei honestly seems to have everything I need but I also really want the skill expression a Battlemaster brings to the table.

The idea of sniping a weapon out of someone's hands with an arrow has always greatly appealed to me.

There's nothing wrong with Fighter/Monk multiclass so you don't worry too much if that is your goal.

But just a note you don't need Battlemaster to disarm someone. Anything that you want to attempt that is not in the rules is simply up to the DM deciding how hard it is and consequently what rolls you need to make to succeed at it. And it's worth noting that the optional DMG rules for Disarm already allow for ranged disarm. So simply talk to the DM and see whether they want to use the DMG rules for Disarm and if not what the alternative rules would be.
