I changed my whole party to variants of Monks. If you want a speed build I think you have it here. Robes staffs/Glaives and the ability to sell a lot of unneeded crap.
You can close i on targets fast.
Decent lock picking
Slapping things with no weapons
Reduce fall damage.
Pole arm mastery is a plus
I goes on and on for pros
A gimmick I know. but wow its a little OP. But who doesn't like taking out a goblin camp in a few turns. Or slapping a boss enemy down in a turn if you focus on them.
Have fun with your game GL all
