Crafting Epic Multi-Stage Boss Fights for TTRPGs

If you’ve ever run a boss fight in a tabletop RPG and felt it didn’t live up to the hype, believe me—you’re not alone. I’ve planned for weeks to make the final showdown epic, only to have my players steamroll the boss in a couple of rounds or lose interest halfway through because it felt like “just another combat.” It can be soul-crushing. Boss fights are supposed to be these grand, nail-biting moments, but they can fall flat without the right structure.
Thankfully, I stumbled across a video from The DM Lair (linked below). It breaks down exactly how to run multi-stage boss fights that are exciting, memorable, and worthy of the big bad you’ve built up over your campaign.
Let’s dive in, shall we?
The Problem with Boss Fights
Before we talk solutions, let’s get real about the challenges. My biggest issue has always been pacing. I’d either design a boss so weak that the party crushed it before it had a chance to shine, or I’d make it so powerful that the players spent three hours chipping away at its health bar with no payoff. Sound familiar?
Another common pitfall: static encounters. If the fight takes place in one boring room with no changes, it can start to feel more like a grind than a climactic battle. And don’t even get me started on the time my players nuked my carefully crafted boss before it even acted. (RIP, Sereg. Defeated via Boop on the nose.)
What Makes a Great Multi-Stage Boss Fight?
Here’s where things get exciting. The key to a great boss fight is treating it like a story within the story. Think of your favorite movie battles: the hero doesn’t just trade punches with the villain. The stakes escalate. The environment shifts. The villain adapts. That’s exactly what you want to emulate in your games.
Here are some tips from The DM Lair that were a good reminder for me—and that I’m hoping my aged brain will retain for my next boss battle:
- Add a Timer: Whether it’s a ritual about to be completed or a collapsing environment, giving players a sense of urgency changes everything. Suddenly, they’re not just trying to win; they’re trying to beat the clock.
- Shake Up the Battlefield: Make the terrain dynamic! Maybe a bridge collapses, lava starts flowing, or new hazards appear. Keeping the environment interesting ensures the fight feels alive.
- Include Minions: Don’t let your boss fight alone. Add waves of minions or lieutenants to keep the party busy and spread the action across all characters.
- Evolve the Boss: Let the villain reveal new powers or tactics as the fight progresses. Keep your players guessing and adapting.
- Roleplay the Boss: This was a big “aha” moment for me. Treat the boss like a character, not just a stat block. Show their confidence in the early stages, their anger as things go wrong, and their desperation when the tide turns. It makes the fight so much more personal.
Breaking It Down: The Stages
The video outlines four stages for a boss fight, and I’m hooked on this structure. Here’s the breakdown:
- Stage 1: Minions and Defense
The boss hangs back, letting their underlings soften up the party. Maybe they’re preparing a ritual or taunting the heroes from a safe distance. - Stage 2: Overconfidence
The boss steps in, testing the waters with flashy but manageable attacks. Think of this as them showing off—players love a villain with a flair for drama. - Stage 3: Adaptation and Anger
Now the gloves come off. The boss starts using their strongest abilities, adapting to the party’s tactics, and showing why they’re the campaign’s big bad. - Stage 4: Desperation
When the boss is on the ropes, they get desperate. Maybe they transform into a monstrous new form, unleash a devastating ultimate ability, or even try to bargain. This stage should push the party to their limits.
Lessons Learned
One of the best takeaways for me was to tie these stages to the boss’s health or key events during the fight. For example, the battlefield might change when the boss drops to 50% health (Bloodied, to use a 4e parlance), or they might reveal a hidden ability after losing their minions. This approach keeps the players engaged and builds tension organically.
Another tip that’s been a lifesaver: foreshadow the mechanics. If your boss has a devastating ultimate ability, drop hints earlier in the campaign. That way, players feel rewarded for paying attention rather than blindsided.
And finally, don’t forget to design each stage so that different character types can shine. Maybe the rogue gets a chance to disarm traps in Stage 1, the barbarian holds off minions in Stage 2, and the wizard counters the boss’s ultimate move in Stage 4. Everyone gets their moment in the spotlight.
Your Next Boss Fight Awaits
Multi-stage boss fights take a little more planning, but the payoff is absolutely worth it. The next time your players face the big bad, they’ll remember it as an epic battle, not just another combat encounter.
Check out The DM Lair’s video for more insights (link below), and let me know in the comments if you’ve tried these strategies or if you have your own tips. Let’s make those bosses unforgettable!

Pathfinder Session Recap: Heart of the Labyrinth

In this First Edition Pathfinder session recap of our Age of Worms campaign, the party faces deadly challenges inside the Heart of the Labyrinth, battles their former ally Kaldir Stormrage, and narrowly escapes the grasp of the infernal devil Pyraxus. Plus, a tense meeting with Elric Toplo uncovers dark truths about the Ebon Triad and the looming Age of Worms. #TTRPG #Pathfinder
Cal Volsung stood at the edge of a nightmare, his hands trembling as the theyrium cocoon whispered promises of power. Its foul essence slithered through his veins, twisting muscle and sinew, turning him into something else. His skin darkened, the edges of his vision swam, and he saw his hands become long, spidery things—drow hands. The curse clung to him tighter than a drowning man’s grip, and no matter how hard he fought, it was there. Oh, he staggered back out of the cocoon’s reach, sure. But the sickness inside him lingered, a poison worming its way into his soul. The others stood in a circle, silent, knowing what they knew but not wanting to say it: Cal was marked. And no one knew if that mark could be erased.
The Heart of the Labyrinth, that wicked engine of doom, sat dead and cold at the chamber’s center. Its once-thundering pulses had gone silent, and for a heartbeat, it felt like the whole world held its breath. Then the air grew heavy, thick as bad dreams. Shadows stretched, slithering up the walls like oil slicks. And that’s when they heard it—a low, rolling chuckle that seemed to come from nowhere and everywhere at once.
It was Pyraxus.
His voice slithered through the air, mocking them, wrapping around their throats like a noose. “You think you’ve won? This maze—my maze—isn’t just gears and stone. It’s flesh and bone. And you? You’re inside me.” His laughter filled every crack, every shadow. The temperature dropped, and the walls seemed to inch closer, like the whole labyrinth was swallowing them whole.
Kaldir Stormrage, the half-dragon berserker, gritted his teeth as the voice wormed its way into his mind. Pyraxus whispered promises sweet as honey and dark as tar—power, brotherhood, purpose. Kaldir, already hanging by a thread, felt that thread snap. His eyes glazed over, and his scales took on a dull, infernal sheen. When he opened his mouth, it wasn’t a man’s roar—it was the guttural bellow of a devil.
The fight was brutal. The party threw everything they had at their former ally, but Kaldir fought like a wild storm, fists and flames battering them with the fury of a god gone mad. They shouted his name and begged him to fight the corruption, but it was like shouting into a storm—he couldn’t hear them. And in the end, they had no choice. Their blades found flesh, and Kaldir fell, his monstrous body hitting the ground with a dull, final thud.
That’s when Pyraxus’ voice came again, dripping with glee. “You think killing him freed him? No, no, his soul is mine now. You only saved him from one prison just to toss him into another.”
Before the party could catch their breath, the treasure hoard at the heart of the Labyrinth began to move. Gold coins lifted into the air like a swarm of angry wasps. Gems glittered with a dark, hateful light as they spun into a storm of metal and malice. The hoard came alive, and it wanted blood.
It was chaos—coins cutting through flesh like razors, gems smashing into armor with bone-shattering force. The party fought tooth and nail to survive the storm, but it was like trying to hold back the tide. They couldn’t win, not like this. Their only hope was the Clockwork Gate at the far end of the chamber, the portal flickering like a candle on the edge of going out.
With trembling hands and racing hearts, they worked together, each second feeling like an hour, assembling the gate piece by piece. And all the while, Pyraxus was in their heads, whispering doubts and fears, filling their minds with images of failure. One wrong move, one missed bolt, and they’d be trapped in the labyrinth forever.
Just as the storm of treasure closed in for the kill, the gate roared to life with a mechanical clatter. They leapt through, one by one, hearts in their throats, as Pyraxus unleashed one final illusion—a blaze of hellfire and chaos, the walls crumbling, the air turning to poison. But the heroes knew it wasn’t real. They had to know. They clenched their eyes shut, gritted their teeth, and stepped through the gate—one last leap of faith.
Tike Myson was the last to step through. As the portal swallowed him, he glanced back over his shoulder one final time. Pyraxus stood at the center of the storm, a devil made of shadows and fire, bound to a prison of his own making. And then, the gate slammed shut, leaving the Labyrinth—and its infernal master—behind.
A Meeting with Elric Toplo
The heroes barely had time to catch their breath before the summons came. Elric Toplo wanted to see them, an old friend of Alfie Bud and a scholar of dark things best left buried. When they arrived at his estate, they were met by Pollard, a wiry old butler whose eyes held too many secrets. He led them through the grand foyer, past ancient suits of armor and faded banners from battles long forgotten. There, among the relics of another time, hung a painting—two boys kicking a soccer ball across a sunlit field. Alfie and Elric, once friends, before the world grew dark around them.
Elric met them in the parlor, a room that smelled of old books and pipe smoke. He was a thin man, his frail frame wrapped in a scholar’s robes, but there was steel in his eyes. When he spoke, it was with the quiet authority of someone who knew too much. And what he knew now was the stuff of nightmares.
Green worms. The kind that don’t just kill you—they take you. They burrow into your flesh, into your mind, turning you into something else. Something worse. And these weren’t just mindless undead; no, these creatures were part of something bigger. They were pieces of Kyuss Descimus, a necromancer who dreamed of godhood and damn near got there. Elric told them how the worms spread like a disease, each one a piece of Kyuss’ mind, each one whispering his will. And the Ebon Triad—they were working to free him. The prophecies were already in motion, gears turning in the shadows, and if the heroes didn’t stop it, the Age of Worms would come.
GM Notes
Running this session was a little like trying to balance on a knife’s edge. It had moments where everything clicked into place like clockwork gears, and others where I could feel things slipping, no matter how tightly I tried to grip the narrative. Here’s where the session shined, and where it didn’t.
What I Liked About The Session
- The Kaldir encounter – a shot at salvation that slipped through their fingers.
I wanted to give the players a real chance to avoid having to fight Kaldir, their ally-turned-berserker. The encounter wasn’t just a hack-and-slash; it was a puzzle wrapped in tragedy. They had different ways to pull him back from the edge—through persuasion, tactics, or skill checks designed to disrupt the mental grip of Pyraxus. Unfortunately, the dice turned cold on them at the worst moment. Still, that’s the kind of heartbreak I love in a game: the players had the tools, the opportunities, but fate had other plans. A gut-wrenching failure makes for a better story than an easy victory any day. - The Escape Protocol – skill checks done right.
Here’s the thing: I’ve got one player whose PC is built to absolutely destroy skill checks—high bonuses stacked across Knowledge and various proficiencies. And yeah, that tends to leave the others twiddling their thumbs when those moments arise. But the Clockwork Gate sequence forced everyone into the spotlight. Sure, Mr. Skill Master got his moment to shine, but this wasn’t just his show. Every player had a role to play; the clock was ticking, the pressure was on, and success was a team effort. That tension, where everyone contributes meaningfully? That’s the gold standard I aim for.
What I Didn’t Like
- The Elric Toplo info dump – when sticking to the script goes sideways.
Here’s where I dropped the ball. I leaned too hard on the published material, which ended up biting me. The whole idea was for Elric Toplo to provide critical intel on the green worms and the Ebon Triad, but my Skill PC had already aced some big rolls earlier, uncovering most of that lore. By the time they met Elric, it felt like a rerun—info they already knew but wrapped in a fancier package. I should have improvised—pivoted off-script and given Elric something new to add, a breadcrumb that wouldn’t spoil future events but still rewarded the players for their patience in getting to that point. Lesson learned: just because it’s written doesn’t mean it can’t be rewritten on the fly. Keep it fresh, keep it dynamic, or risk having those high-stakes moments fall flat.
Pathfinder Age of Worms Campaign: Cogsworth Labyrinth Adventure Recap

This is the summary from the last First Edition Pathfinder gaming session of my Age of Worms campaign. It probably won’t make too much sense for those familiar with the campaign—or anyone outside my group of players, for that matter. In this side quest, the heroes known as the Ruinlords (Pathfinder punny joke, lol) had discovered a maze called the Cogsworth Labyrinth that was said to hold the dragon hoard of the bronze dragon Pyraxus. And now, we pick up from there.
The Cogsworth Labyrinth wasn’t just a maze—it was a death trap with teeth, and the Ruinlords were stuck in its jaws. They moved cautiously, but even the air felt wrong, thick with the charge of something waiting to strike. The heroes didn’t have to wait very long. The veins of Theyrium (a powerful ore believed to have originated in the Abyss) running through the walls pulsed once, then exploded into life, twisting into long tendrils like crystalline vipers. Each one cracked free with a sound that cut through the stillness like a bone snapping. They didn’t just lash out—they hunted, driven by something far worse than instinct.
The fight was a blur of blood, sweat, and desperation. No time to think, no time to plan—just survive. Barely. But they did, and when the last of those glowing tendrils shattered to dust, the party pressed forward, deeper into the guts of the Labyrinth. They found themselves in a place built for violence: the arena. Towering curved metal walls surrounded them, casting eerie green light from the Theyrium veins embedded in the structure. In the center stood a hulking mass of death—the Crowd Pummeler 9-60, a mechanical monstrosity designed to kill, and it locked onto them the moment they stepped inside.
The Pummeler didn’t hold back. Every blow felt like a freight train, every second stretched out into a brutal eternity. But the Ruinlords weren’t pushovers. They dug deep, working together, finding weak spots, until finally, the machine faltered. But even in its death throes, the Pummeler whispered a grim warning: the defences around the Heart of the Labyrinth were ramping up, preparing for something worse.
The party limped onward, finding temporary relief in a chamber called the Gnomish Recovery Matrix, though ‘relief’ was a generous word. The machines in the room were meant to heal, but nothing in this place came without a catch. Kaldir Stormrage—half-dragon, half-berserker, all fury—had been broken by the Theyrium, his mind lost to madness. The Matrix gave him a chance, though, filtering the corruption from his system long enough for him to regain his senses. But Kaldir wasn’t calm. There was too much fire in his eyes, too much fear. He’d been in the Labyrinth for so long, twisted by the Theyrium, searching for the dragon Pyraxus—who he believed was his blood relative. The heroes wanted to help Kaldir find the dragon’s lair, but their motivation was more financial than altruistic.
They pushed on into the Workshop of Cogsworth, where the air smelled of old metal and broken dreams. This was where things got personal. Trixwynn Cogsworth greeted them, having been left to die by her aunt and the original creator of the labyrinth, Valeria Cogsworth. Trixwynn was barely recognizable as the gnome she once was. She’d fused herself with a monstrous machine, a scorpion-like horror powered by Theyrium, and she wasn’t sane anymore. Her mind was as broken as the machines around her, twisted by centuries of isolation and rage. Trixwynn ranted, her words sharp with bitterness and madness, promising to make the party suffer, promising they would see the true power of Theyrium before they died.
Trixwynn summoned a giant elemental, its body crackling with raw electricity, the air around it humming with the promise of violence. It surged forward like a living storm, all fury and power, crashing into the heroes with relentless strikes. They fought back, hard and fast, but it was like trying to punch a thunderstorm. When the elemental finally went down in a shower of sparks, the air smelled like scorched metal and burned flesh.
Then Trixwynn made her move. The gnome-turned-machine barreled into the fray, her mechanized body a blur of steel and fury. It was chaos. Flesh against metal. Magic against machine. The whole fight felt like the Labyrinth had come alive, watching them, waiting for them to make a mistake. Cal saw his opening in the madness, the Command Rod heavy in his hand. He jammed it into place and rerouted the Theyrium’s power, hoping it would shut this nightmare down.
But as Trixwynn fell, her last words sliced through the noise: resetting the Heart wouldn’t end things—it would set something far worse free. Her voice lingered like a bad omen, and then everything went dark.
The doors slammed shut with a shudder that felt final, like the Labyrinth was locking them in, sealing their fate. The Ruinlords stood there, trapped, nothing but the heavy sound of their breathing filling the silence. And in the distance, low and steady, they could hear it—a rumble, growing louder with each second. The ground shook, and the walls trembled. Then, all became as silent as a tomb.
GM Notes
Now, I’m diving into some GM notes on what I learned from this session. Part of the reason I’m writing this is because if I’m learning something, maybe it can help another GM out there too. If you’re one of my players reading this, you might want to stop here—there could be spoilers ahead! See you at the next session!
A Little About My Pathfinder Group
My Pathfinder group gets together about twice a month, with each session running roughly four hours. Depending on how things are going, that can sometimes stretch longer. For this particular session, I had planned for the game to end as the players entered the final room, where they would be confronted by the huge lightning elemental and the Scorpion Gnome. But the players weren’t interested in waiting until the next session to face the Big Boss, so they asked if we could keep going.
I agreed, but looking back, I kinda wished I hadn’t.
What I Liked About the Session
Gnomish Recovery Matrix:
This room provided a good break from the heavy combat flow. The players had just dealt with three Theyrium Tendril snakes, followed by a tough fight with the Crowd Pummeler. They were running low on resources, and the Gnomish Recovery Matrix gave them a chance to recover and learn more about their new ally, Kaldir. While I could’ve fleshed out the room a bit more, it served its purpose in pacing and character development.
What I Didn’t Like
The Combats:
My table has 5 to 6 players, and we can usually squeeze two combat encounters into a session. This time, though, we had three—one of which involved a powerful henchman and then the Big Boss herself. By the time they reached the final fight, it felt like more of the same. Each encounter had a solo, hard-hitting target, and there wasn’t enough variety to keep things interesting. The fights blended together in my mind. The fighter who specialized in “dirty tricks” (debuffs) was frustrated because most of the enemies were immune to his debuffs. I think if I had mixed up the types of creatures and introduced different mechanics, it would have been more engaging for everyone, including me.
The Prep:
As I mentioned earlier, I had planned for the session to end when they met the Big Boss, leaving a nice cliffhanger. I had the lightning elemental and Trixwynn prepared just in case, but what I didn’t have ready was what came after. The players had the Control Rod to reset the labyrinth, but I hadn’t finished the mechanics on how that would work. That was entirely on me.
Lessons Learned:
- Variety matters: Mix up creature types and mechanics to keep combat encounters fresh and engaging.
- Balance pacing: Consider breaking up combat with exploration, puzzles, or role-playing to avoid burnout.
- Prep beyond the immediate: Always be ready for what comes after the Big Boss fight—your players might surprise you by pushing forward.
- Adapt, but with limits: Be willing to extend sessions, but keep an eye on player fatigue and your own preparedness.

A couple of days after this session, I came across this video by Basic Liches on YouTube. In fact, watching the video prompted me to write this blog post. So, if you’re not into the blah blah blah of the written word, check out their great video linked below.
Rise of the Runelords – Episode 52

The Saviors of Sandpoint found themselves deep beneath Jorgenfist, home of the stone giant wizard Mokmurian. As if stone giants and baby dragons weren’t bad enough, there was also a matter of magic thousands of years old asserting its presence.
How does one deal with such adversity? Why, with figurative gun blazing of course!

Rise of the Runelords – Episode 50
The Saviors of Sandpoint did a service for Riddleport crime lord Elias Tammerhawk. In return, Elias put them in the capable hands of one of his agents who took them to the Valley of the Black Tower. Shortcuts became lethal, and just when the heroes thought they were making headway they bumped into something – or someone – that should not exist.
