The Abyss Walker is a path of solitude, emptiness, and the lack of emotion. Those that walk it trade their soul for understanding. However, to manipulate and utilize such a dark magic could result in immense power and immaculate arcane control. 

Level 3: Abyssal Mind

You have an amount of Abyssal Points that refill during a Short or Long Rest. The max of equal to 2 + your Wisdom Modifier. Roll a d100, if the total is equal to or higher than 50, you open your mind to the Abyss and temporarily transport your soul to the Abyssal Realm. Here, those around you whisper their true thoughts and intentions. You can also use this to quickly teleport, though this costs you. As a Bonus Action, you can spend an Abyssal Point to traverse the Abyss up to 20 away. 

Level 9: Abyssal Restoration

Use the decay of the dead within the Abyss to reform tissue and flesh. As an Action, you can touch a creature within 5 ft of you, transporting both of your souls to the Abyss. There, you use the infinite decay around you to heal the creature. Spend an amount of Abyssal Points you choose and heal them for 1d6 Hit Points per Abyssal Point. In real time, you and the creature were only gone for but a second. You can use this to instead bring an unconscious creature back, restoring their Hit Points by 1d4s instead of 1d6s. 

Level 13: Abyssal Grasp

Your connection to the Abyss runs deep, allowing you to manipulate its energy in combat. As a Bonus Action, you can spend one of your Abyssal Points to reach into the Abyss and briefly pull a creature into it. Choose one creature you can see within 30 feet. That creature must make a Wisdom saving throw against your Rogue Spell Save DC (8 + your proficiency bonus + your Wisdom modifier). On a failed save, the creature is pulled into a personal demiplane for a single moment, appearing to vanish from the battlefield for less than one second. On its next turn, the creature's speed is halved, and it has disadvantage on the first attack roll it makes. They live through their worst fears, their anxiety or depression, and are haunted by the things they've done all for what feels like hours to them, which brings them back fearful. 

Level 17: Abyssal Reflection

Your control over the Abyss is so strong you can use it to protect yourself from harm. When you are targeted by an attack, you can use your Reaction to momentarily slip into the Abyss. You take no damage from the attack and instead, you create a distorted reflection of yourself that momentarily emerges from the Abyss to attack the creature that targeted you. Make a melee spell attack roll against the attacker using your Wisdom modifier. On a hit, the attacker takes 5d8 force damage.

You can use this feature a number of times equal to your Wisdom modifier (minimum of once). You regain all expended uses when you finish a long rest.
