Monastic Tradition:
Way of the Sōhei
Armed combat is simply another form of martial art, one perfected by the followers of the Way of the Sōhei. By honing and blending various weapon styles, these soldier monks turn their armaments into extensions of their own bodies. Monasteries of Sōhei can serve training grounds for armies, and a Sōhei is always ready to make the warzone their own. Their weapon is a brush, and the battlefield is their canvas.
Art of War
When you choose this tradition at 3rd level, your training in armed martial arts leads you to master many weapons. You have proficiency with all martial melee weapons that lack the heavy and special properties. These count as monk weapons for you.
Additionally, weapons count as half their weight for determining carrying capacity.
Deflect Weapons
Also at 3rd level, when you are hit with a melee weapon attack from a creature within 5 feet of you, you can spend 1 ki point to attempt to parry the attack away as a reaction. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier + your monk level. If you reduce the damage to 0, you can make a melee weapon attack against that creature as part of the same reaction.
Spiral Of Strikes
At 6th level, your fluidity with your monk weapons grows. Your attacks with your monk weapons count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage, and when you make an attack with a monk weapon, you can draw or stow a weapon as part of the attack.
Also, when you the attack action with an unarmed strike or a monk weapon on your turn, you can make one attack with a monk weapon as a bonus action.
At 11th level, when you use Flurry of Blows, the attacks can be with a monk weapon rather than unarmed strikes.
Warrior's Cry
Beginning at 11th level, you can empower yourself to stand tall against armies. When you take the Dash or Dodge action on your turn, and gain resistance to bludgeoning, piercing, and slashing damage until the start of your next turn.
Unerring Accuracy
At 17th level, your mastery of weapons grants you incredible accuracy. If you make an attack roll with a monk weapon and miss, you can reroll it. You can only reroll one attack on each of your turns. Additionally, once per turn when you hit with a melee attack, you can spend 1 ki point to treat the attack as a critical hit.
