If you don’t have any mutations roll on the mutated area table and then choose which mutation you get from the available mutations on this origin table 2 Soul Furnace: Once per short rest as an action you can emit magical, divine energy from your body, each creature within a 10ft radius of you makes a dexterity saving throw (DC 15) or takes 2d6 fire and 3d6 radiant damage, or half on a success (you automatically fail the save) 3 Seraphic Step: Your walking speed increases by 10ft and you can hover in the air for 10ft during your movement, your footprints leave a faint glow and sparkle, making them easy to track 4 Righteous Fury: Once per day you can choose to succeed a death save as if it was a natural 20, getting back up on 1 hit point and taking your turn as normal, when you do you have a semi-permanent death fail for the next three days (if using this ability causes you to have three permanent death fails at a single time you stay alive until you hit zero hit points at which point you instantly die) D4 Full Body 1 Become Aasimar: You are reincarnated as an Aasimar of the DM's choice 2 Purity of Form: You gain immunity to poison and diseases but vulnerability to radiant damage and whenever you gain new mutations after this one you take 2d12 radiant damage at the trigger time, if the damage dealt is 24 or higher the mutation does not manifest 3 Soul for a soul: You can cast the True Resurrection spell once using this feature without material components however you instantly die 4 Idealisation: You become an idealised version of yourself, your highest stat becomes 22 if it is not already higher and your alignment becomes good, however if you ever change alignment for whatever reason this stat becomes 10 Diabolic A land touched by the plane of hell, all life in this biome either burns or Influence sins, whichever comes first Biome Planar Influence: Whenever a creature makes an infection check in the biome it also makes a charisma saving throw DC 10 or have its alignment temporarily changed to the alignment of the plane for 24 hours [Lawful Evil].

D4 Mind 1 Deal Broker: When you write on any surface you can choose to make it a magical contract, when at least two creatures sign the contract (even with a fake name or someone else’s name) they are magically bound to the contract, if anyone who signed the contract breaks it they are subjected to whatever the agreed forfeit of the contract is. You can cast a spell on the contract to act as the forfeit, the spell slot is used but nothing happens until a creature breaks the contract, at which point they immediately fail the saving throw of the spell and it is cast centred or targeted on them. If a contract offers one’s soul that soul goes to hell (even if it is good) and is transformed into a devil, that creature cannot be resurrected by anything short of a Wish spell. Your alignment becomes lawful, each time you are revived your alignment moves one step closer to evil 2 The Hound: Once per day as a bonus action you can summon a Hell Hound that is under your control in the closest unoccupied space, but your sanity score is reduced by 2 and you must maintain concentration on controlling the Hell Hound, if your concentration is broken the Hell Hound regards you as an enemy and fights until death 3 The Death Note: Upon getting this mutation write down on a piece of paper the name of one other creature that is known to you then give this note to the DM, for added fun do not tell anyone else in the party who’s name you wrote down. When you die, that creature instantly dies. If the target creature dies before you, is already dead or does not exist (in the case that you write down a fake name) you gain one use of the spell Power Word Kill that you can cast using this feature without needing to use verbal, semantic or material components. When you cast this spell in this way you instantly die (even if the target of the spell does not) 4 Devilish Denizen: A diabolical spirit attaches itself to your consciousness (similar to an Aasimar’s angelic being) when you drop to 0 hit points the devil will offer to make a deal with you, accepting the deal ensures that your next death save succeeds as if it were a natural 20 but the devil may ask you to complete a task or give up something of its choice as payment D4 Head 1 Forked Tongue: You have advantage on intimidation checks but disadvantage on persuasion checks (and performance checks that require your voice) 2 Black Mirror: You can view the world as if it was a hellish nightmare, when you do you can see people as terrifying fiends based on the sins they committed. You have advantage on insight checks made to sense motive, but your sanity score decreases by 4 3 Silver Tongue: You forget two languages chosen by the DM (if possible not Infernal or Common) but you have advantage on persuasion checks made to persuade or charm 4 Doom’s Eye: One of your eyes turns red with black sclera. Once using this feature, you can fire a Death Ray at a creature you choose within 30ft of you, the target makes a dex save (DC 16) or takes 10d10 ___ damage. When you use this feature you also take the same damage as if you had failed the saving throw, if the Death Ray reduces a creature to 0 hit points the creature instantly dies. Regardless of whether you live or die when using this feature, you also lose the eye and this mutation (creatures with one eye have disadvantage on perception checks) D4 Arm 1 Dark Arms: Your unarmed strikes with this hand deal 1d4 ___ damage, but you have disadvantage on animal handling and sleight of hand checks 2 Infernal Ire: Immediately when developing this mutation take 1d10 + your Constitution modifier of ___ damage as wrought iron chains manifest and burn into your flesh. Your arm is bound in chains made from infernal iron, you can grapple a creature within 15ft of you with these chains, if you do you can both move normally but cannot move more than 15ft away from each other while tethered in this way. Once per turn you can deal 1d10 + your Constitution modifier of ___ damage to all creatures touching the chains (including yourself) 3 Cursed Horde: Your arm loses all flesh and muscle leaving only the bones of your hand and arm. You learn the spell Animate Dead, once a day using this feature you can touch a corpse or pile of bones and cast Animate Dead without expending a spell slot, but you gain vulnerability to radiant damage 4 Hand of Hell: Holding an arcane focus, holy symbol or component pouch in this hand or otherwise casting spells cast with this arm change the spells damage to ___ damage D4 Chest 1 Diabolical Wings: You cannot wear heavy or medium armour; you gain a flying speed of 30ft 2 Barbed Back: You grow spikey barbs like a Barbed Devil. You cannot wear heavy or medium armour but at the start of each of your turns you deal 1d10 + your constitution modifier piercing damage to any creature grappling you 3 Feeding Fissure: A fissure appears across your chest; a glowing light emanates from inside.
