Rethiarius the Sentinel

As part of the Expedition to the Barrier Peaks campaign, my PCs took on their first boss. 8 PCs and 4 Henchmen/NPCs with an average level of 6. The boss was a Rubik-like cube robot/mechanical entity called Rethiarius. Corrupted by a creature known as a Telepath (a reskinned mind flayer, inspired by Prey 2017). The […]

Adimarchus/Phaeros (Boss Fight for 5e)

During the early days of 3.5e I ran the Shackled City Adventure Path. I and my players really enjoyed this first Adventure Path, however, one thing I never liked was the final boss fight with Admiarchus. The way the battle was designed and the way 3.5e combat rules work it ended up just being a […]

Vampire King Boss Fight (5e)

I built this for Curse of Strahd some time back but never got to use it as my PCs voted not to play Curse. I dug this up as my PCs as part of my Clash of the Titans campaign when they went to visit the Blood King as a Halloween adventure, and, of course, ended […]

Anumaramon (Boss Fight)

We finished the Oriental Campaign today with a final battle with Anumaramon. My PCs were level 20 and they just full on frontal assaulted the palace while their armies were engaging the Typhoon Guard. I made it clear, the Typhoon Guard, which is mostly oni, would win if the PCs didn’t deal with Anumaramon and […]

Rimiko of the Five Storms

Original adventure used a yukka-onna – a type of white lady ghost undead. I replaced her with a Five Storm Wind/Ice oni named Rimiko. The fight had two phases with the second phase potentially triggering a dominated kami but my PCs stopped the ritual before that happened. This was the boss fight that ended the […]

BOSS FIGHT: UNITY 2.0

I had an opportunity to rerun this boss with updates (below) as part of the adventure conversion “Dawn of the Overmind“. When the PCs entered the Penumbra system Ilsensine decided to intervene. The next time they had a long rest they entered a dream where they had to fight UNITY. If they failed not only […]

BOSS FIGHT: UNITY, IRON GODDESS (PHASE 3)

I originally planned to have the UNITY fight staggered as I didn’t expect the characters to rest after they started engaging UNITY directly. Though the fights are not one after the other I consider them one big fight in that context with the UNITY AI directly harassing the players via spells and minions. PHASE […]

THE GODMIND

This is the matrix like world of UNITY. She will have to be defeated here before true victory is gained. Here are the general effects of this alternate/demi-plane. THE GODMIND EFFECTS Depending on the victory level of the characters the following affects are permanently active and can not be dispelled within the Godmind and constantly […]

BOSS FIGHT: UNITY (PHASE 2)

I originally planed to have the UNITY fight staggered as I didn’t expect the characters to rest after they started engaging UNITY directly. Though the fights are not one after the other I consider them one big fight in that context with the UNITY AI directly harassing the players via spells an minions. […]
