Their immortal nature is no longer a part of the Rakshasa's being and can no longer count on the long, painful process of resurrection upon an initial defeat, but they still live a long life compared to many denizens of the Material Plane. They start their new life with the same body at the end of their previous, and can naturally live from 500-700.

True Rakshasa are creatures of cruelty and malice. While their reformed counterparts may have drifted from the extreme of the true fiendish ways, that is not to say that some of their less desirable traits have not carried over. Although they still, by a vast majority, conform the the Lawful ways of structure and order of the Nine Hells, reformed Rakshasa could range anywhere from Evil to Good, the later being more rare. 

As usual, Rakshasa range from 6 to 8 feet in height. Your Size is Medium.

Your base walking speed is 30 feet. 

Same as your darker brethren, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have Proficiency in the Deception and Insight skills.

Unless you yourself are of Good alignment, you are vulnerable to Piercing from Magic Weapons Wielded by Good Creatures.

Your claws remain as sharp as ever. Your unarmed strikes may deal 1d4 damage plus your Strength modifier. In addition, if you are of Neutral or Evil alignment, you retain a slightly diminished version of your cursed claw. The target is cursed if it is a creature. The magical curse takes effect whenever the target takes a short or long rest, filling the target's thoughts with horrible images and dreams. The cursed target gains no benefit from finishing a short or long rest. The effects last for 1d6 days or until it is lifted by a remove curse spell or similar magic.

You retain a limited number of single use-spells from your former existence as an infernal being. 
You know the minor illusion cantrip. At third-level, you can cast the disguise self spell as a 1st-level spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the charm person spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 13th level, you can cast the mislead spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 17th level, you can cast the plane shift spell once with this trait and regain the ability to do so when you finish a long rest. Charisma is your spellcasting ability for these spells

You can speak, read, and write Common and Infernal.
