@MythicalAvioseIs the martial arts ability for the monk equivalent to finesse for the purposes of feats like Defensive Duelist? I'd rule yes

@kurai01 @mikemearlsGiven the resurgence of interest in Monk, Jeremy would you agree here? Monk weapon, not unarmed. Defensive Duelist requires a finesse weapon. Martial Arts doesn't confer the finesse property.
