Description
Abaddon is a Demon who's flesh has been melted and formed with a metal shell suited specifically to his anatomy. His years of torment ignited a fire in his heart that burned hotter than the fires he burned in for centuries. When he escaped his eternal imprisonment, he began creating a following with the demons in the demiplane of the Goddess Loviatar. He wrested control of the plane from it's creator, and now uses it as a headquarters for his demon army.
Abaddon has recently sought to expand his demonic empire to the material plane, where he hopes to bring the world under a new order of tyranny.
Abaddon's physical form mostly consists of a dark metal and flame with demonic runes decorating his metal body.
Lair and Lair Actions
Abaddon's Lair resides in an abandoned stone castle, known as Castle Embersol. The castle was recently rebuilt for Abaddon's purposes, being a headquarters for his demonic armies. His lair specifically resides in the throne room, a dim-lit large open room with stone pillars holding the ceiling up. Torches are the only light source other than the feint orange glow of Abaddon's body.
Lair Actions
On initiative count 1 (losing initiative ties), Abaddon takes a lair action to cause one of the following effects; Abaddon can’t use the same effect two rounds in a row:
- (Only usable after 5 rounds has passed and can be used no more than 10 times.) The ceiling begins to fall at random places in the throne room. Roll a d20, if the roll is above 12, characters within 10ft centered around a player of your choosing must make a Dexterity save of 18. On a fail, they take (4d12) Bludgeoning damage and are knocked prone underneath the rubble. On success, they are moved out of range of the falling ceiling in any direction the player chooses.
- (After the first lair action is all out of uses) Griffons begin to swarm the skies above Castle Embersol. Roll a d20, when lower than 10, a griffon swoops down and attacks Abaddon for 15 Slashing damage. When higher than 10, a griffon swoops down and attacks a random player.
Regional Effects
The region containing Abaddon's has the following effects:
- The sky becomes red with blue aurora borealis streaking across within 2 miles of Castle Embersol
- Random Demons of any CR below 15 can be found roaming about. never in packs greater than 3
If Abaddon dies, these effects fade instantly.

Posted Jan 30, 2024Welp, this is a doozy. His counterspell might as well not exist, because at that level it won't work vs the wizard or sorc.
Funny enough, getting close to him is a dumb idea, not because he has 5 attacks with like, 50 average dmg, but the Frightened effect from his aura doesn't specify a save, or even a duration, so I assume it's permanent. Also he can just spam his fear attack so basically martial characters are just not even a thing this fight. His multiattack doesn't even specify which attacks he has to use... not like he'd do anything other than the greatsword.
Just, prepare heroes feast before the fight, fly like, 60ft, and throw down saving throw spells to exhaust his legendary resistance, his CHR save sucks, then planeshift him. He doesn't have that himself, so the going anywhere removes him from the game, but air or earth is your best bet. Also his form isn't immutable so polymorph is an option
His legendary actions are super op because he can apparently reduce your ac to like, 10 before you get your turn then hit you 5 times.
He notably lacks truesight, or even Devils sight, so magical darkness is actually a good option. Or a rogue with greater invisibility. That can chip him down, albeit slowly.
I don't see why he need an ability to regain health when he has over 1.4k effective hp 🤣🤣🤣
