Path of the 13 Plum Blossoms

Monastic Tradition based on using the Qiang Spear (bamboo spear or flower spear) as their primary form of attack. 

Qiang Spear: Reach/Finesse. Monk weapon. 1D4, damage scales as other monk weapons do. Wielding this weapon requires 2 hands, you can replace your unarmed attacks in flurry of blows with spear attacks, wielding the spear prevents you from catching and returning missiles on a successful 'Deflect Missile'. 

Plum Blossom Technique

Plum Blossom Technique: starting at 3rd level, you can manipulate your enemy's ki when you harness your own. Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:

• It must succeed on a Dexterity saving throw or be knocked prone.
• It must make a Strength saving throw. If it fails, you can push it up to 15 feet away from you.

Agile Parry

Agile Parry. Starting at 3rd level if you successfully strike with your your Qiang Spear as part of the Attack action on you turn, you can use it to defend yourself. You gain a +2 bonus to AC until the start of your next turn against that opponent, while the Qiang Spear is in your hand and you aren’t incapacitated.

Ki-Empowered Qiang

Starting at 6th level your Qiang Spear counts as a magical weapon for the purposes of overcoming resistance and immunity to non-magical attacks and damages.

Redirected Attack

Starting at 6th level when a creature misses you with a melee attack roll, you can spend 1 ki point as a reaction to cause that attack to hit one creature of your choice, other than the attacker, that you can see within 5 feet of you.

Opportunity of 13 Blossoms

Starting at 11th level you can exploit a creature's momentary distraction when it is hit by an attack. Whenever a creature you threaten is hit by an attack made by a creature other than you, you can spend a Ki point to make a melee attack against that creature.

Accuracy of 13 Plum Blossoms

Starting at 17th level your mastery of your spear grants you extraordinary accuracy. If you miss with an attack roll using your Qiang Spear on your turn, you can reroll it. You can use this feature only once on each of your turns.
