least number of levels to get weapon training?

[Hobit of Bree]

Say you are playing a high-level character that isn't a fighter or otherwise have access to weapon training (the fighter class feature). What is the fastest one could gain access to the ability? Mostly thinking about Gloves of Dueling.

3 levels of Weapon Master Fighter.

[Oxnard Kettlebeak]

Only other ways I know to get it are Myrmidarch Magus and VMC Fighter. . .

[VoodistMonk]

Yep, Weapon Master 3 is your golden ticket...

5 levels of Arsenal Chaplain Warpriest, or 6 levels of Sohei Monk can get it legit, as well.

Thanks folks. 3 levels is probably too much for what I was thinking, but good to know!
