Monks of the Way of the Shinobi tend to be silent assassins, trained to kill in the trickiest of manners, but also in the most fierce ones. Some decide to follow a peaceful life, while others may decide to dedicate to the art of killing. Either way, Monks of the Way of the Shinobi excel in the arts and crafts as well.

At 6th-level, you become proficient with the Smith’s tools and can forge, provided you have certain materials, specific Ninja weapons. These weapons have certain characteristics and can be crafted in 1d4 days:

Name	Weapon Type	Damage	Properties	Crafting Requirements

• Kusarigama. This weapon is a sickle connected with a chain to a spiked weight. The feat Polearm Master grants the usage of the weight attached at the end of the chain. The weight can be used as a bonus action and it deals 1d4 bludgeoning damage. On a hit, the target needs to succeed on a Strength saving throw or falls prone. Additionally, the feat Polearm Master allows for this weapon to increase its reach by 10 ft. (total reach, 15 ft.).

• Ninjatou. This weapon is a straight, thin sword. On a critical hit, a target hit point maximum takes a penalty equal to the weapon’s damage.

• Kunai. This weapon is similar to a shuriken. However, unlike the shuriken, it can also be used on a melee fashion. When used this way, you can choose to either inflict piercing or slashing damage.

• Makibishi. This weapon is a small, pointy fragment. It is generally used for traps or for creating difficult terrain while dealing mild damage. As an action, you can throw these weapons on the ground, in a 10-squared-foot area. This area is treated as difficult terrain and any creature entering it takes automatically 1d4 piercing damage. Additionally, you can make a ranged attack with these weapons. Your attack has advantage.

You are proficient with all these weapons and you treat them like Monk weapons regardless of their properties.
