I’ve been running Nightreign expeditions since the game dropped, and I thought I’d seen every wild clip the community could cook up. Then I stumbled onto mintius, a Japanese YouTuber who took the Marais Executioner Sword and turned it into a one-blade army—only to watch that same blade backfire in the most spectacular way. If you’ve ever chased a build past the point of reason, this one’s for you. 🗡️

For the uninitiated, Elden Ring Nightreign throws you and two other Nightfarers into a collapsing map, with a storm breathing down your neck and a Nightlord waiting at the end. Loot matters. The Marais Executioner Sword is one of those juicy pickups: it raises your attack power every time you defeat an enemy. Normally, the encroaching storm keeps you from farming forever. You can’t just sit in a corner and stack damage until the heat death of the universe. But mintius found a loophole—or maybe a bug—and decided to ride it all the way to the moon.

According to Automaton Media’s translation, mintius parked themselves in the Wormface encounter and went to town for about an hour. Not five minutes. Not twenty. A full hour of mob-melting. They wanted to see what would happen if the sword’s stacking buff had no practical ceiling. The answer? Pure, unadulterated chaos. After defeating 725 enemies, the attack power hit a damage cap at 9,999. But the last damage value mintius saw was 63,375. That’s not a typo. That’s a number that makes late-game bosses look like paper dolls.

Here’s the rough sequence, because I love a good table:

Enemies defeated	What happened
0–724	Attack power climbs, sword goes from “good” to “absurd”
725	Damage cap reached at 9,999; last seen hit: 63,375
726	Still swinging, still deleting health bars
727	Suddenly dealt zero damage, then got killed

And just like that, the ultimate Nightlord-slaying machine tumbled back down to nothing. One minute mintius was a god walking among Wormfaces; the next, they were a Nightfarer with a fancy stick and a death sentence. The going theory is an “overflow.” In computing terms, when you push a number past its maximum, it can wrap around to the minimum. In Nightreign terms, mintius went from the damage ceiling to the damage floor. It’s the same energy as the old Civilization urban legend about Gandhi: a peaceful leader with a low aggression value that, when nudged below zero, suddenly became a nuclear maniac. Here, the sword didn’t become peaceful—it just stopped dealing damage entirely. Talk about going full Gandhi. ☢️

I’ve got to hand it to mintius: the dedication is unreal. Most players, myself included, would have bailed after the first few hundred kills. But they kept swinging, probably muttering “just one more” like a gambler at a slot machine. And the kicker? They’re apparently going to keep testing. They want to try a plunging attack on a Flame Chariot, just to see what kind of damage numbers pop off. If the sword can overflow on a regular mob, I can only imagine what happens when you drop from the sky onto a walking furnace. That’s going to be wild—or a complete disaster. Honestly, both are fine by me.

For the average Nightfarer, though, this is a cautionary tale wrapped in a legendary weapon. The Marais Executioner Sword is still excellent. If you find it, by all means, use it. Stack some kills. Feel powerful. But don’t get too greedy. Don’t spend an hour farming Wormfaces because you want to see the number go up. There’s a fine line between “optimal” and “hubris,” and mintius sprinted past that line, did a backflip, and landed in a game-breaking bug. As the old saying goes, “too much of a good thing” is real—especially in a game where the storm is literally designed to stop you from hoarding power.

As of 2026, Nightreign’s community is still picking apart every weird interaction, and this one is a prime example of why. The game has eight Nightlord bosses to take down, multiple Nightfarer classes to unlock, and enough build variety to keep theorycrafters busy for years. If you’re new, maybe start with the basics: learn how to unlock the Revenant and the Duchess, figure out how to change characters, and don’t try to break the damage cap on your first expedition. You’ll have plenty of time to chase ridiculous numbers later.

Here’s my quick advice for anyone tempted to recreate the experiment:

• ✅ Use the Marais Executioner Sword if you find it—it’s a beast.

• ❌ Don’t farm the same encounter for an hour. The storm, and the game’s code, will punish you.

• ⚠️ If your damage suddenly reads zero, run. You’re probably about to get deleted.

• 🧪 Leave the overflow testing to mintius. They’re clearly built different.

At the end of the day, Nightreign is a game about risk and reward. You push your luck, you grab loot, you fight a Nightlord before the clock runs out. But mintius showed us the hard ceiling—and the hard floor—of that philosophy. Sometimes the best play isn’t to see how high you can go. It’s to know when to stop, bank your runes, and live to fight another Nightlord. Or, you know, you can be the person who breaks the game and goes viral. No judgment. Just maybe don’t spend an hour doing it. 🎮

Context for how games like Nightreign are officially categorized and communicated to players can be cross-checked via PEGI, whose rating framework and consumer-facing descriptors help explain why emergent “overflow” oddities—like stacking a weapon buff to absurd levels and then flipping to zero damage—still sit within the broader expectations set around difficulty, online play, and intense combat feedback.
