Dark Mana. Devils live in the underworld, and are associated with every negative thing in the world, their mana reflects this. Your mana counts as Dark Mana. Also, you cannot become Berserk from using Dark Mana, unless it's caused by one of your spells.

Monstrous Biology. All devils have monstrous bodies, being much warped compared to the creatures outside the Underworld. Your type is Fiend. Also, you gain 4 Biology Points. You can choose how to spend them at character creation, choosing options from the Devil Biology section.

Natural-Born Deceivers. You have proficiency in the Deception skill.

Devils' Sixth Sense. A devil has an unnatural sense when it comes to potential prey. As an action, you can open your awareness to detect mortal souls. Until the start of your next turn, you become aware of every humanoid soul within 60 feet of you. You know whether the soul is living or dead or if it is bound to an object, but do not learn the soul's identity. Additionally, you feel a pull in the general direction of the soul, but do not learn their exact location.

Additional Language. Having spent more time among mortal civilization, you learn one additional language of your choice which you and the GM agree fits the character.

Hellish Resistance. You have resistance to fire damage.

Infernal Disguise. As an action, you can make yourself appear as a member of another race. If you disguise yourself as a race that lacks horns, wings or a tail, those features disappear and you lose the ability to fly or use your tail attack if you have them; otherwise, your game statistics don't change. You determine the specifics of the changes, including race, sex, skin tone, hair length and coloration, eye color and appearance, etc. You must adopt a form that is humanoid. You can also adjust your height and weight, but not so much that your size changes. You can change the appearance of your clothes with this feature, but not your armor or equipment. While disguised in this way, no amount of physical scrutiny or investigation can identify you as a devil; only magic can reveal your fiendish nature. While Disguised, you can use an action to materialize your wings or tail, granting you the ability to fly or the use your tail attack if you have them, but all creatures that can see you are immediately made aware you are a Devil. You stay in the new form until you use an action to revert to your true form or until you die.

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