D&D 5E Artifact to combat Demogorgon

[Tyler Dunn]

If someone was to have Demogorgon as the final boss of their campaign, and wanted to make an artifact to give to the party to make the fight more fair, what would that artifact do?

What level are the PCs and what Demogorgon are you using? Depending on these you might not need anything.

 

[Tyler Dunn]

The PCs are Level 20 and I'm using Mordenkainen's Tome of Foes Demogorgon.

Just make sure they all have + magic items to attack and AC... at least +1

A Banana: there's no way his left head and right snake arm can resist! He'll beat himself up for it.

That or the Book of Exalted Deeds.

If it is a typical 4-6 PC group you don't need anything to weaken him. The PCs are likely to steam roll him pretty heavy. I would instead suggest making him tougher. Either use the new mythic concept from Theros, or the buffed Demogorgon in my 5e Epic Updates: Demon Princes & Lords

I don't think you need anything special, at least depending on the group. Give them hints as to what they're facing and a bit of prep and they should be fine depending on your setup. I think you may be surprised how easily your big bad is defeated.

Single monsters do not stand much of a chance against parties several levels below their CR, although I wouldn't be surprised if the party loses a member or two. Even using base calculations, if the demogorgon is alone it's only ranks as a "hard" encounter. If you really want this to be a penultimate fight, I'd consider setting up the environment to favor the demogorgon a bit and throw in some minions that run away once the boss is defeated.

@Tyler Dunn , I have made a buffed up Mythic Demogorgon for you. This way the regular CR 28 Demogorgon might be strong enough take a lvl 20 group, but if you end up needing more of challenge, just activate the mythic trait and then your in for a real battle.

If the PCs are level 20 then you're going to want to give that artifact to Demogorgon if he's to have any chance to not get completely crushed.

Something that turned his two heads – left head Aameul and right head Hethradiah – against each other would be apropos. A good starting point would be an inversion of the ettin's Two Heads feature, accounting for Demogorgon's condition immunities, so something like this...

Demogorgon has disadvantage on Wisdom (Perception) checks and on saving throws against being blinded,
deafened, stunned, and knocked unconscious. Additionally, Demogorgon loses its immunity to being charmed and frightened.
