Sasuke

After the Fourth Shinobi World War, Sasuke lost his left arm. He gained tremendous power and a Rinnegan from the Sage of Six Paths during the war. He had been relying more on his Rinnegan in combat since then. 

Lost arm

You lost your left arm but you become better at fighting with your right arm. When you make a melee weapon attack, you can add your Charisma Modifier to the attack roll. Furthermore, your right arm becomes stronger after years of practice. You can choose to master one heavy weapon with two-handed property (Eg. Greatsword). You then gain proficiency with it and are able to wield it with one hand. 

Uchiha Jutsu and Ocular Power

You learn your jutsu from the Uchiha clan, Kakashi and Orochimaru. The following spells are added to the warlock spell list for you.

Rinnegan awaken

Your Rinnegan on your left eye allows you to use a Space-Time Ninjutsu at will. Starting at 1st level, as a bonus action, you can instantly swap places with an object or a willing creature you can see.

Additionally, when you take damage, you may use your Reaction to halve the damage against you and swap places with an object or a willing creature you can see. Once you use this feature, you can’t use it again until you finish a short or long rest.

Summoning Jutsu and Lightning Release

Starting at 6th level, when you cast the spell find steed, you can summon a Giant Eagle, a Giant Constrictor Snake or any creature with a Challenge Rating of 1 or below. Additionally, when you hit a creature with a weapon attack, you can expend a warlock spell slot to deal an extra 1d8 lightning damage to the target, plus another 1d8 per level of the spell slot, and you can knock the target prone if it is huge or smaller. You also gain resistance to lightning damage.

Eternal Mangekyō Sharingan- Susanoo

Starting at 10th level, you learn the Arcane Hand spell, which doesn't count against your number of warlock spells known. You can cast it once using a warlock spell slot. When you cast the spell using this feature, the Arcane Hand emits purple light within 10 feet of the hand and it always moves with you even when you teleport. You can't do so again until you finish a short or long rest. 

Additionally, you gain the following benefits when you are under the effects of the spell: 
- You have advantage when making a Constitution saving throw to maintain your concentration.
- You cannot be frightened or charmed. 
- You can apply Lightning Release to Grasping Hand and Clenched Fist.
- You add your Charisma modifier to the AC of the hand. 

Eternal Mangekyō Sharingan- Amaterasu

Starting at 14th level, you can choose on a point you can see with your Eternal Mangekyō Sharingan and produce black flames in a 40-foot-radius, 20-foot-high cylinder centred on that point. Any creature of your choice in the region must make a Dexterity saving throw. A creature takes 7d10 necrotic damage on a failed save, or half as much damage on a successful one. The black flames cannot be extinguished in any way unless the user chooses to put out the flame as a bonus action. The flames continue to burn for seven days until everything has turned to ash. A creature takes an additional 3d10 necrotic damage when it enters the area with black flames for the first time or ends its turn there. 

When you apply Amaterasu to your Susanno, whenever a creature within 5 feet of you hits you with a melee attack. The attackers take 3d10 necrotic damage per attack. 

Once you use this feature, you can’t use it again until you finish a long rest.
