Well you could always start a new thread and reserve more posts for yourself.
Why would monks be duellist? They can't even use a shield so there's no reason not to use two weapons no? And if they were wielding a single weapon well it'd be a heavy one not a one hander.
Wouldn't two weapon fighting be the classic monk? Two fists afterall.
It's in the text that monk weapons can be whatever the DM will allow. So, DM willing a monk swashbuckler (open fist most likely) can have unarmored defense, high resistance to all magic, a rapier, fisticuffs, and amazing physical stunts all in one package.
I am the flush of excitement. The blush on the cheek. I am the Rouge!
