Honestly, if you’ve been spending any significant time in Aeternum lately, you know the meta is basically a shifting desert. Things change fast. One day you’re dominating OPR with a bow, the next you’re getting flattened by a heavy bruiser who seems to have infinite sustain. But then the Rage of Osiris New World artifact dropped, and suddenly, the conversation shifted. It isn't just another piece of gear to toss into your storage shed alongside those dusty gathering charms. It’s a literal cornerstone for specific builds that want to punish enemies for simply existing.
New World has always had a complicated relationship with its gear. We went from the days of "Resilient" being the only perk that mattered to this new era of Artifacts that actually change how your buttons work. The Rage of Osiris is a heavy headpiece, and it’s unapologetically aggressive. If you're the type of player who likes to dive into the backline and cause absolute chaos, this is probably sitting at the top of your farm list. Or at least, it should be.
What Rage of Osiris Actually Does (And Why It’s Scary)
Let's look at the raw mechanics because that’s where the "rage" actually comes from. This isn't a defensive helm despite being heavy. It’s built around a very specific perk called Osiris's Wrath. Basically, when you take damage, you gain a stack of a specific buff. Once you hit top stacks—usually around 10—you lose the stacks but gain a massive surge in damage and movement speed.

It’s a "berserker" mechanic.
Think about it. In a crowded 3v3 Arena match or a chaotic point capture in War, you are going to get hit. It’s inevitable. Most gear tries to help you survive that hit. Rage of Osiris says, "Go ahead, hit me, I'll just hit you back twice as hard." You get a 15% damage increase once it procs. That is a massive number in the current math of New World. Most perks give you 2% or 5%. Fifteen percent is the difference between an enemy escaping with a sliver of health and them becoming a ghost at the nearest campfire.
How to Get Your Hands on It
You can't just buy this off the Trading Post. Amazon Games loves a good grind, and the Rage of Osiris New World artifact follows that tradition. You’ve got to head into the Glacial Tarn expedition. But it’s not just a casual run-through. It typically drops from the final boss, Ser Loth, on Mutated difficulties.
The drop rate? It’s RNG. Some people get it on their first M2 run. Others are twenty runs deep and still wearing a purple helm they found in a chest three months ago. That’s the nature of the beast. You need to be prepared for the ice mechanics of that dungeon, which feels ironic considering you're hunting for an artifact named after an Egyptian sun god.
The Upgrade Path is the Real Journey
Finding the helm is only half the battle. When it first drops, it's at Gear Score 650. To make it truly viable for end-game content, you have to complete the artifact quests to unlock its full potential and bump it to Gear Score 700. This usually involves:
- Killing a specific number of Ancients in Brimstone Sands.
- Completing a certain number of PvP kills while the helm is equipped.
- Finishing a high-level breach or world event.
Once you’ve done the legwork, you take it to a Gypsum Oven. You’ll need a Weapon Matrix, some Dark Matter, and a heap of gold. It’s expensive. But for a piece of gear that defines your entire playstyle? It’s worth every coin.
The Best Builds for Rage of Osiris
You shouldn't just slap this on any build. If you're a glass cannon musket player sitting 50 meters away, you aren't getting hit enough to trigger the stacks. You’re wasting the slot.
The Rage of Osiris New World artifact shines in the thick of it.

The Great Axe/War Hammer Bruiser: This is the classic choice. You’re already in the "clump." You’re taking chip damage from fire staffs and stray arrows. You’ll hit your 10 stacks in seconds. When that 15% damage kicks in alongside your Mauler perks, your Maelstrom starts hitting like a literal truck.
The Flail Tank: This is a bit more niche but surprisingly effective. Since the Flail scales with Focus and Strength, and often relies on being surrounded to trigger heals, the Rage of Osiris provides that extra offensive pressure that tanks usually lack. You become a threat, not just a meat shield.
Medium Blunderbuss/Sword and Shield: If you like the "Disruptor" role, this is it. You dive in, bash someone with a shield, take a few hits, and then unleash a boosted Shrapnel Blast. It’s oppressive.
Why Some Players Hate This Artifact
It’s not all sunshine and desert heat. There is a vocal part of the community that thinks the Rage of Osiris New World is a bit "brainless." The argument is that it rewards bad positioning. Normally, taking damage is a mistake. With this helm, taking damage is a strategy.
There's also the "visual clarity" issue. When the proc happens, there is a distinct visual effect, but in a 50v50 War, everything is a mess of neon circles and explosions. It can be hard to tell when an opponent has just turned into a god-king. If you aren't paying attention to their buff bar, you might try to trade hits with them only to realize far too late that they have a 15% damage lead on you.

Also, let's talk about the weight. It’s a Heavy headpiece. This means if you’re trying to stay in a Light equipment load for that sweet dodge roll, you have to be very careful with the rest of your armor. You’ll likely have to wear all light pieces in every other slot just to stay under the limit. Most people just commit to a Medium or Heavy build when using it.
The Counter-Play: How Not to Die
If you see someone glowing with that Osiris aura, stop hitting them. I know, it sounds counter-intuitive in a combat game. But the buff is temporary. If you can kite them for those few seconds, the stacks reset and they lose the bonus.
Stuns and CC (Crowd Control) are your best friends here. A well-placed Ice Shower or a Hammer Stun can burn through their "rage" window without them landing a single hit. The Rage of Osiris makes people play aggressively—sometimes too aggressively. They get tunnel vision. Use that against them. Lead them into a trap or away from their healers.
Is It Still Meta in 2026?
Looking at the current state of Aeternum, the meta has shifted toward more mobility, but raw power never goes out of style. While newer artifacts have introduced "teleportation" mechanics and weird elemental conversions, the Rage of Osiris New World remains a top-tier pick for anyone who wants to play a frontline role. It’s reliable. You know exactly what you’re getting.
In a game where some perks feel like you need a PhD in mathematics to understand if they are actually working, Osiris is simple. Get hit. Get mad. Do more damage.
Final Thoughts on the Grind
Is it worth the 20 runs of Glacial Tarn? Yeah. Probably. Even if you don't use it every day, having it in your armory for specific mutations or OPR matches is smart. It’s one of those items that defines an era of New World design—moving away from passive stats and toward "active" gear that requires you to change your rhythm.
If you’re struggling to find a group for the farm, keep an eye on the Recruitment channel specifically for M2 runs. Most veteran players are still running it to help friends or to farm the Dark Matter anyway.
Actionable Next Steps for Players
- Check your current weight load: If you plan on using Rage of Osiris, start crafting or buying Light armor pieces with Health or Refreshing perks so you can balance the heavy weight of the helm.
- Farm the Glacial Tarn: Set aside a weekend to run this on at least M2. Don't burn yourself out on M1s; the drop rate is significantly lower.
- Save your Weapon Matrix: Don't waste your matrices on mid-tier gear. Save them for when the helm finally drops so you can hit Gear Score 700 immediately.
- Test in 3v3 Arenas: This is the best place to learn the "timing" of the stacks. You’ll learn exactly how much punishment you can take before the damage boost kicks in, allowing you to time your big cooldowns for that specific window.
