Path of the Insect-Nin (Shinobi World Supplement)

Path of the Insect-Nin

The Path of the Insect-Nin is not for the light of heart, nor for those who would let their morality stand in the way of certain victory. At birth, an insect-nin is offered to various swarms of shinobi insects. Upon acceptance, the insects burrow into the user's body, gaining direct access to their chakra supply in exchange for moderating their host's bodily functions and following their orders unquestioningly.

Hive Body

At 3rd level, your body has been enhanced by the Parasitic Destruction Insect jutsu, becoming a hive for one kind of shinobi insect. As an action or bonus action for 4+ chakra, you may create a swarm of the chosen species of shinobi insect anywhere within 5 ft. of you that has as many chakra points as you spent. Any swarms you create have an additional number of hit points equal to your proficiency bonus. Your swarms' bites count as unarmed strikes for all of your features and jutsu except Martial Arts, they use your proficiency instead of theirs, and you may add your proficiency bonus to their Bites' attack roll. When you cast a jutsu, you may cast it from your space or any of your swarms' spaces.

As an action, you may absorb one swarm you have created, regaining any chakra they still have. If one of these swarms spends more than 5 minutes between being created and absorbed, or if it drops to 0 chakra points, it dies instantly.

Your swarms are controlled by you, act on your turn, and use your actions and bonus actions. When you take the Attack action, they may make attacks as well. Any DCs the insects have are equal to your jutsu save DC. These attacks count as yours for the sake of how many attacks you can make when you take the Attack action.

Hidden Swarms

At 7th level, you begin to master the insect-nin art of espionage. As a bonus action, you may split it into two Tiny swarms. Tiny swarms have advantage on Stealth rolls, any damage dice they roll are decreased by 1 tier (i.e. 1d6/2d4 ← 1d4 ← 1) and have half as many chakra and hit points as the swarm they were created from. While two Tiny swarms are within 5 ft. of each other, you may combine them into one Small swarm as a bonus action. Additionally, you may communicate telepathically with your swarms.

Massive Swarms

At 10th level, you may create swarms of a second species of shinobi insect for 2 additional chakra. As a bonus action while two of your swarms are within 5 ft. of each other, you may combine them into a single swarm one size larger to a maximum of Gargantuan. They gain both swarm's features, gain any effects effecting either swarm, any damage dice they roll are increased by 1 tier (i.e. 1d4 → 2d4 → 3d4), have the combined chakra and hit points of the swarms they were created from, and gain a number of temporary hit points equal to your jutsu attack bonus that are lost when they defuse.

Insect Divebomb

At 15th level, when you damage a creature within one of your swarm's reach, the target takes additional damage equal to half the swarm's unarmed strike damage. Additionally, your swarm's attacks deal an additional 1d4 damage when they have advantage, and you may walk on your swarms as if they were solid terrain.

Total Insect Composition

At 20th level, you are more insect than nin. You may occupy another creature's space and vice versa, and you can move through any opening large enough for a Tiny insect. You gain any features, actions, resistances, and immunities your swarms have, and count as one of your swarms for the sake of this subclass's features. As a bonus action, you and your swarms may convert any amount of your hit points into half as many chakra points, or your chakra points into twice as many hit points. Doing so can not increase your chakra or hit points above their respective maximums.

Ninja Art: Honey Bee

Cost: 6 chakra

Duration: 1 minute

As a reaction when one of your swarms is dropped to 0 hit points by 1 creature within 5 feet of it, the insects that comprise the swarm explode into thick, chakra-infused honey. The creature that killed the swarm must attempt a Dexterity saving throw. On a failure, their movement speed is halved and they gain disadvantage on saving throws, ability checks, and attack rolls that rely on Dexterity.

Floating Bugs

Human Cocoon

Cost: 3+ chakra

As an action, your insects spin a tight cocoon connected to one surface within 5 feet. The cocoon appears as a bright source of chakra, but blocks any potential chakra inside from being identified. A Medium or smaller creature may allow a cocoon to be wound around them. Each cocoon tears apart if it carries more than 500 pounds, has 1 hit point, and has a closable hole large enough to stick one's head out of. Any objects within a cocoon counts as weighing half as much for things outside of the cocoon.

Insect Pillar

Cost: 3 chakra

As a bonus action, one of your swarms extends its size upwards a number of feet equal to its flying speed until the end of your turn, forcing all targets of your choice within its space to make a Strength saving throw. On a failure, they take the swarm's bite attack damage. On a success, they take half as much.

Parasitic Destruction Insects: Eclipse

Requirements: Insect Pillar

Cost: 5 chakra

As an action on the same turn as you used Insect Pillar, you collapse the pillar, covering a wide area in hungry, quickly moving insects. The swarm loses its upward size increase and all creatures of your choice in a radius equal to its flying speed, as well as those within its space, must attempt a Strength saving throw. On a failure, they take the swarm's bite attack damage. On a success, they take half as much.

Forbidden Technique: Jar of Poison

Cost: 40 chakra

Requirements: Rinkaichu

Duration: Indefinite, minimum 1 day

Range 1+ miles

As an action, you place a swarm of Rinkaichu in a pit (20 ft. radius minimum) with at least 10 dead creatures that are not constructs or elementals, sealing the top of pit with a one way sealing jutsu. When you either choose to release the seal or die, the seal lowers. If at least 1 day has passed, the gasses inside ignite on contact with fresh air, pushing the poison of the Rinkaichu into the air covering this jutsu's range in a thick poisonous smog that counts as heavily obscured for any creature without the Path of the Assassin. Non insect-nin creatures that start their turn within this area must make a Constitution saving throw at the end of each of their turns, becoming poisoned for 1 minute and taking 2d6 poison damage on a failure. Creatures can repeat this saving throw at the end of each of their turns, ending this effect on a success.

You may place additional dead creatures that are not constructs or elementals in the pit before it is released, increasing this jutsu's range by half a mile. Spending an additional day before releasing the seal increases this jutsu's range by 1 mile.

The poison cloud lasts for a number of minutes equal to the miles it covers or until a strong wind (at least 20 miles per hour) disperses it. A wind of moderate or greater speed (at least 10 miles per hour) disperses a 15 ft. radius area within the cloud.

You may target one additional creature with this jutsu for every 2 additional chakra points spent.

Secret Technique: Leaching Insects

Requirements: Secret Technique: Insect Sphere

Cost: 8 Chakra

As a bonus action, a creature restrained by Secret Technique: Insect Sphere must attempt a Constitution saving throw. On a failure they lose 1d4 chakra points, and one of your swarms regains an equal number of chakra points. You may choose for the swarm to not regain chakra points to cause the target to lose twice as many.

Secret Technique: Insect Jar Technique

Cost: 8 chakra

Creatures that attempt to must attempt a Strength saving throw, taking 1d8 slashing damage, not passing through the sphere, and being unable to attempt to cross the sphere until the beginning of their next turn on a failure. Area of effects from outside of the sphere do not target creatures inside the sphere, and area of effects from inside the sphere do not target creatures outside the sphere.

You may spend 4 chakra as an action to cause the giant insect you created to become charmed by you for 1 hour, otherwise it goes berserk.

*Secret Technique: Bug Bomb*

Requirements: Rasengan

Cost: 14 chakra

Range: 40 feet

As an action, you gather your insects in a ball that feeds off of a mass of collected chakra that disperses on contact, creating a large explosion not many can escape from.

Regardless of if the attack was successful or not, all creatures of your choice within 15 feet must make a Constitution saving throw or take 2d6 poison damage and become poisoned for 1 minute. They may retry this saving throw at the end of each of their turns, ending this effect early on a success.
