We will cover our bodies in powdered milk, thus the base negates the acid. Who cares if we look silly?  This just makes me want to redo Taijun using a bow, is that okay DM?  He's basically a pack mule at this point!  I looked at the style feats and most I won't qualify for until certain levels because of BaB.  I knew Monks are terrible but I'm still up for the challenge.

Here's the an alternate version of Taijun:
STR: 12 DEX: 16  CON: 10 INT : 10 WIS: 18(includes human bonus) CHA: 8
Hp: 8  AC: 17/17t/14ff   INIT: +3
Feats: 1st - Weapon Proficiency Longbow, Humand bonus - Weapon Finesse, Monk bonus - Deflect Arrows, Or maybe Scorpion Style
Traits:
Robot Slayer (+1attack, +1dodge vs robots),
Improvised Defense (You’re never defenseless, even when you are caught off guard. Benefit(s): Whenever you wield an improvised weapon, you gain a +1 shield bonus to AC. If you use the improvised weapon to attack, you lose this shield bonus until the beginning of your next turn.

I think Monks substitute their level for BAB when qualifying for style feats.

If you want to use a bow you should consider choosing the Zen Archer Monk archetype. They're one of the best archers in the game, and they're basically "instant archer in a box".
