Medium: unarmed melee build?

[Lass]

I'm considering playing a medium in an upcoming game but I am wondering if there is a way to build it to focus on melee, probably focusing on the Champion, Guardian and Marshal spirits. Is there a way to get some monk stuff in there? Its a 20 point build game.

What level(s) are you looking to play?

I think Medium is best focused on melee with Champion. Champion works best with extra attacks because it's got lots of static damage bonuses. So Two Weapon Fighting or Unachained Monk or something weirder like a Magus dip are going to help.

I'd probably grab one level of Scaled Fist Unchained Monk and go for a Dex/Cha build, with moderate Str/Con. I'd also grab Legendary Influence, which is near-mandatory for Mediums IMHO. Scribe Scroll/Craft Wondrous for Heirophant/Archmage, Spirit Focus for Champion, and you've still got three other feats for fun.

Interesting ideas. I am starting at level 1 and going to aprox 16 as the AP dictates. So it seems clear that if my medium is going to be an unarmed fighter I will need to dip into either Brawler or Monk then.

Be mindful that the champion's sudden attack power explicitly says it doesn't stack with flurry of blows.

I'd consider taking one level of brawler, enough Dex to qualify for TWF, then TWF your unarmed strike and your other unarmed strike, since TWF does stack with sudden attack.
