Can a player character ascend (or descend depending on how you look at it) to become a demon or Devil, somehow?

My PC is a Warlock under the Archfiend Patron. While I understand I could potentially work out a means for my character to become a devil with my DM, I was wondering if there is an actual RAW, or other complex means of doing so through RAW mechanics or spells?

Specifically, I'm looking for a means of obtaining a demon-like status, not transforming into a fiend species. I'd like to retain my current race and personality, but perhaps jump into the hierarchy of fiends, demons, and devils. I'm thinking this is mainly a house ruled affair, but I'm curious to see if anyone may have info from actual officially released mechanics or rules, or a way to use said mechanics to acquire the result I'm looking for.

Short Answer: No. Not in 5e, yet anyway.

Looong Answer

I checked the Abyss book hoping there was something, but there wasn't. In previous editions, there were several ways to do it. BECMI Immortal rules, Necromancer's Handbook, and Planescape, for instance.


So from those, here's some Setting As Written and Rules As Written approaches, to getting you toward a Fiendish Template without a Polymorph spell changing your race.

First, you will need to change your home plane to a lower plane, instead of the prime material plane. How you do this varies. You can do this and just about everything else by using a wish, but if you can find an easier way, you should.

Second, you want to have a way of getting to your plane. That will help represent your nature better. There is a Boon here:

Boon of PLANAR TRAVEL When you gain this boon, choose a plane of existence other than the Material Plane. You can now use an action to cast the plane shift spell (no spell slot or components required), targeting yourself only, and travel to the chosen plane, or from that plane back to the Material Plane. Once you use this boon, you can't use it again until you finish a short rest (DMG. p 232)

Third, you want to live as long as lower planar creatures live, which is irritatingly enough, forever.

BOON OF IMMORTALITY You stop aging. You are immune to any effect that would age you, and you can't die from old age.

Next, you will want to be able to survive the total terrain of, well, you know, lakes of fire, and all those breath weapons and fire balls being used by your neighbors.

BOON OF THE FIRE SOUL You have immunity to fire damage. You can also cast burning hands (save DC 15) at will, without using a speL slot or any components.

So far, you still look like you, act like you, but you now live in hell, will live there forever, and can swim in the lake of fire with your neighbors. If you are killed on the Prime Material Plane, in theory, if you changed your home plane, you should be banished to that Lower Plane you switched to. This also means your Prime Material Type has been changed to a Planar Material type, making you subject to all the restrictions, banishment, wards, etc.

These rules do not currently exist in 5th edition in a direct way. They are legally touched upon in the individual spells, but unlike editions with Planescape, you will have a lot of work to do to compile all the information and rules as they apply to the 5th edition. Like I said, a wish probably has about a 100% chance of being able to do this, but how your DM rules the wish, or whether they want it to succeed makes it safer to try other approaches, rather than being default polymorphed into some low CR fiend like a lemure.

The boon of perfect health would probably help, but not all fiends are immune to things like all diseases or all poisons, only some of them, on average. Technically, there's a few fiends not immune to fire - the ones on layers of ice, so its not a necessary condition either. Only changing your home plane is really critical, and since its a plane of dead petitioners turned into immortal demons or devils, you too will have to be immortal just to keep up.

Speculation, not RAW Take the Actor Feat if your Charisma isn't maxed, (i.e.e liar/charlatan/disguises and a forked tongue charisma bonus), and then get really good at summoning and leading fiends. There used to be a blood war in the lower planes. If your DM still uses it, sign up and lead a small army or group against high value targets. Bonus points if you trick good PCs into helping you. This builds up the reputation you need among the NPC demons and devils.

Certain Eldritch Invocations from your warlock class can also help build the myth. Like Devil's Sight, Mask of Many Faces/Myriad Forms (the higher ranked devils tend to assume many different forms to deceive people), and one with the shadows to disappear anywhere near darkness.

As a non mechanical DM approach, you may attempt to successfully take out the competition or one of your Archfiend's Rivals directly, and in a humiliating way, such as through a successful Imprisonment spell. These escapades lay the ground work for qualifying for Boons, like the ones above.

True Names & Promotion

Promotion and Demotion. When the soul of an evil mortal sinks into the Nine Hells, it takes on the physical form of a wretched lemure. Archdevils and greater devils have the power to promote lemures to lesser devils. Archdevils can promote lesser devils to greater devils, and Asmodeus alone can promote a greater devil to archdevil status. This diabolic promotion invokes a brief, painful transformation, with the devil's memories passing intact from one form to the next.(MM p.67)

DEVIL TRUE NAMES AND TALISMANS A mortal who learns a devil's true name can use powerful summoning magic to call the devil from the Nine Hells and bind it into service... However it is summoned, a devil brought to the Material Plane typically resents being pressed into service. However, the devil seizes every opportunity to corrupt its summoner so that the summoner's soul ends up in the Nine Hells. (MM p.67)

You can see that the rules as written are really keen on turning you into a low level nearly mindless weak demon, following the traditional promotion path. The only real way to circumnavigate that is to have some kind of magically binding contract or artifact, or literally take over the throne of an existing quasi-power, for example, by using the above imprisonment spell and successfully using Deception, Intimidation, and Persuasion to take over their lieutenants. But this is mere speculation of a Hostile Takeover.

Unfortunately, 5th edition still lacks considerable amounts of useful info on player characters and the planes.

In the Descent into Avernus campaign, an NPC can be met as a human and if he dies will show up again in Avernus as an Amnizu. It's suggested to be a direct result of a very plot-important pact he made with an Archduke of Hell. So I'd say the easiest method is to make a pact where one of the components of it is that you become a fiend upon your death.


While I agree mostly with the boons bringing you as close to the things fiends usually have aside from every other special ability, the ways to really become a devil are:

  • To be Lawful Evil and die, to then spawn as a Lemure in the Nine Hells (MM, p. 69):

A lemure arises when a mortal soul is twisted by evil and banished to the Nine Hells for eternity. The lowest type of devil, lemures are repugnant, shapeless creatures doomed to suffer torment until they are promoted to a higher form of devil, most commonly an imp.

  • To sell your soul to a devil and hoping they will keep you as a Lemure below them instead of having you minted into a soul coin

  • To True Polymorph/Shapechange into one (easiest on high level)

  • To cast Wish
