Path Of The Orochi

Those who walk the path of the Orochi specialize and trained in the ancient art of assassination, and subterfuge yet choose to act as an iron wall between their foes and their wards. Specializing in a playstyle that makes them the biggest toughest target, that emphasizes lying in wait and unleashing a retaliatory blow with devastating force. One who walks the path of the Orochi can shrug off the attacks of those who dare stand against them, and often are the sole survivors of an altercation.

Level 3: Intonjutsu

At 3rd level, you have learned to conceal your presence using smoke bombs. As a bonus action, you can drop a smoke bomb at your location or a location within 30 feet of you. A cloud of thick smoke pours out in a 10-foot radius from the bomb. The cloud's area is heavily obscured to all creatures but you. The smoke cloud lasts for one round. 

You can have a number of smoke bombs on your person equal to your proficiency bonus. When you complete a short rest, you may create a new set of smoke bombs.

You can also conjure shuriken or kunai to strike at your foes. As a bonus action, you can manifest a single magical kunai or shuriken (using the stats of a dagger) and immediately hurl them, making a ranged attack. A kunai or shuriken vanishes if you don't hurl it right away, and they disappear right after they hit or miss. At 9th Level when you hit a target with a kunai or shuriken, you may use your Brutal strike feature on each attack you make until the end of your next turn.

 You also gain proficiency with the herbalist's and poisoner's kit

Rasetsu

At 6th level, you have to siphon the vitality of your foes to augment your body. Every time an enemy suffers from your bonus rage damage , you gain double the damage dealt by the bonus rage damage  as temp hp. While you have temporary hit points, you don’t trigger attacks of opportunity by your movement, have advantage on stealth checks and attack rolls. These temporary hit points last for one hour. At 9th Level you include the damage dealt by your brutal strike feature in the temporary hit point calculation.

Ninpo

At 10th level, you have special shinobi arts for confusing, disrupting and crippling your foes. You gain the following abilities.

• Enhanced Smoke Bomb: Your smoke bomb now has a radius of 30 feet and a range of 60 feet. Friendly creatures no longer have their vision obscured your smoke bomb.
• Shinobi Toxin: You can change your brutal strike damage to magical poison damage. While you have temporary hit points, you may change the entire attack’s damage to magical poison damage.
• Enhanced Arsenal: You gain a bonus to hit and damage rolls with your kunai and shuriken from your Intonjutsu feature equal to half your proficiency bonus rounded down.

Wrath of The Orochi

At 14th level, you have mastered the Orochi's path and have honed your skills to perfection. Your Ratestu now grants temporary hit points equal to triple the damage of your rage bonus damage+brutal strike. If the target has attacked you since your last turn, you may make a free kunai or shuriken attack whenever you make a weapon attack during your turn. This ability cannot trigger itself.

Your kunai and shuriken now mark creatures struck by them. The mark lasts for one round. Whenever a friendly creature is hit by a marked creature that is within your melee range, you may consume the mark and make one weapon attack as a reaction  and on a hit you may reduce the damage dealt to your ally by an amount equal to the poison damage you dealt.
