You’ve been grinding. I know how it goes. You finally get your hands on the latest gear in the Act 2 update, you slot everything in, and then… nothing. The damage numbers just aren’t popping like they should. Honestly, it’s frustrating. Most players are hitting a wall with their Lune Act 2 build because they’re still playing like it’s Act 1, relying on raw burst when the new mechanics are actually screaming for something a bit more nuanced.
Act 2 changed the math. It’s not just about stacking "Eclipse" stacks anymore.
If you’re wondering why that boss in the Sunken Vault is still laughing at your DPS, it’s likely because of how the internal cooldowns on the "Silver Thread" passive are interacting with your main rotation. Basically, the developers tweaked the frame data. If you aren't animation canceling the secondary proc, you're losing about 15% of your total output. That's huge. Let's get into what actually works right now.
The Core Mechanics of a Modern Lune Act 2 Build
The biggest mistake people make? Ignoring the Resonance shift. In Act 1, you could basically ignore your mana-to-health ratio as long as you had enough lifesteal. In Act 2, the "Moonlight Surge" buff scales directly with your current percentage of "Astral Clarity."
It’s a balancing act. You want to be aggressive, but if you bottom out your resources, your damage floor drops through the basement.
Think of your build as a battery. If you’re just draining it constantly, you never hit that peak discharge state. Most high-level players, specifically those pushing the Tier 5 trials, have moved toward a "Cycle-Heavy" setup. This involves using the Fractured Crescent as your primary engine. It feels a bit clunky at first. I get it. But once you realize that the crescent procs a secondary explosion on every third hit during a dash-cancel, the game changes.
You’ve got to watch your positioning, too. Act 2 introduced more environmental hazards that interact with "Lunar" tags. If you stand in the shimmering pools while casting "Nocturnal Beam," you actually get a 10% cast speed reduction that isn't mentioned clearly in the tooltip. It’s a hidden nerf, or maybe a bug, but it’s there.
Gear That Actually Matters (And What To Trash)
Let's talk about the Void-Stitched Raiment. Everyone was hyped for it when the patch notes dropped. "Look at those base stats!" they said. Well, they were wrong. The Raiment has a terrible synergy with the current Lune Act 2 build meta because its defensive proc resets your "Spectral Momentum" stacks.
You're literally paying for defense by throwing away your offense. Instead, you should be looking for the Withered Silk Wrap.
Yes, it’s a lower rarity. Yes, it looks less impressive. But the "Fading Light" passive it carries allows for a 4-second window where your skills cost zero resources. That’s your window. That’s when you dump your entire rotation.
Why Scaling Crit Isn’t Always the Answer
We all love big yellow numbers. It's a dopamine hit. But in Act 2, enemies have much higher "Resilience" stats. This means your critical hits are being mitigated more than your flat elemental damage. I’ve been testing a "Pure Flux" variation that focuses on "Overcharge" rather than "Crit Chance."
- Primary Stat: Flux Intensity.
- Secondary Stat: Cooldown Recovery.
- Tertiary Stat: Movement Speed (Seriously, don't sleep on this).
If you can’t move, you can’t maintain the "Orbital" buff. And if you lose "Orbital," your build basically stops functioning. Movement is DPS in this game. You should be aiming for at least a 120% base speed before you even think about entering the higher-difficulty zones.
The Skill Rotation You’re Messing Up
Stop lead-in casting with "Lunar Flare." Just stop. It’s slow, it leaves you vulnerable, and it doesn't apply the "Chill" debuff fast enough to trigger your passive bonuses.
Instead, you want to start with "Phase Shift." Use it to get behind the target. This triggers the "Backstabber" modifier which, thanks to the Act 2 rework, now applies to magical projectiles for the first two seconds of combat. Follow that immediately with "Star-Fall," then—and only then—use your "Flare" to consume the marks.

It’s a rhythm. 1-2-3-Pause. 1-2-3-Pause.
If you spam, you’ll trigger the "Internal Exhaustion" mechanic. You’ll see a little grey icon on your buff bar. If you see that, you’ve already messed up. It means your Lune Act 2 build is overheating. Take a second. Reposition. Let the bar clear. You’ll do more damage in the long run by doing nothing for half a second than by mashing buttons while exhausted.
Understanding the "Aether" Infusion
One thing people often overlook is the "Aether" infusion on the secondary weapon slot. Even if you never swing your off-hand sword, the stats still apply to your main-hand spells. You want a "Soul-Bound" prefix here. It grants a passive 5% life-leech to all "Lune" abilities.
Without this, you’re going to be chugging potions like a madman, which interrupts your casting animation.
Hard Truths About the Current Meta
The community is split. Half the people on the forums say that "Lunar" builds are dead and everyone should swap to "Solar" for the fire-over-time procs. They’re wrong, but they aren't completely crazy. "Solar" is easier. It’s "braindead" damage.
A proper Lune Act 2 build requires more effort, but the ceiling is much higher. We’re talking about a 40% difference in potential output if you’re hitting your "Perfect Timings."
But it's hard.
You have to be okay with dying a few times while you learn the "Glimmer" window. This is a tiny frame during the "Eclipse" animation where you are completely invulnerable. If you can master that, you don't need defensive gear. You can go full glass cannon. But if you're playing on a high-latency connection? Forget it. Just build for tankiness. There’s no shame in it.
I’ve seen "Bruiser Lune" builds clear the final Act 2 boss in under six minutes. It’s slower, sure, but it’s consistent.
Fact-Checking Common Advice
You might have heard that "Willpower" is the most important stat for Act 2. That was true for the first three days after launch. Then the developers shadow-patched the "Willpower" scaling because players were hitting for millions. Now, "Willpower" has heavy diminishing returns after 40 points.
If you have 60 points in "Willpower," you’re wasting 20 points that could be in "Agility" or "Fortitude."
Go to the stat reset NPC in the Moonlit Outpost. It costs 5,000 gold, which is a bit steep, but it's worth it. Reallocate those excess points into "Haste." You want your animations to be as snappy as possible. In a game where boss telegraphs are only 0.5 seconds long, "Haste" is literally a survival stat.
The Role of Relics
Don’t just equip whatever shiny gold relic drops. For a Lune Act 2 build, the Broken Compass is actually better than the Eye of the Storm.
The Compass gives you a flat 10% chance to reset your dash cooldown on every kill. In mob-heavy rooms, this makes you effectively infinite. You become a blur. The Eye of the Storm sounds cool with its lightning procs, but it actually scales off "Strength," which your build likely has zero of. Don't fall for the trap of high-rarity items that don't fit your core scaling.
Navigating the End-Game Grind
Once you hit level 50 in Act 2, the game changes again. You start finding "Corrupted" gear.
This stuff is risky. A "Corrupted" piece of gear will give you a massive boost to one stat but subtract from another. For this specific build, you are looking for "Corrupted" items that take away your "Health Regeneration." Why? Because you should be getting all your health from the "Soul-Bound" off-hand leech we talked about earlier.
Passive regen is useless in a high-intensity fight. You’re either at full health because you’re dealing damage, or you’re dead because you got hit by a one-shot mechanic.

A Note on Team Play
If you’re running in a group, your role changes. You aren't just a damage dealer; you’re a "Mark" bot. Your "Lune" abilities apply a "Silver Exposure" debuff. This makes your teammates deal 5% more damage.
It stacks.
If you have two players running a Lune Act 2 build, you can keep that debuff up 100% of the time. This is why "Lune" players are always in demand for the "Nebula Raids." Even if your personal damage is lower than the "Solar" guy, you’re making the whole team better.
Making Your Build Real: Actionable Steps
Stop theory-crafting and go test your numbers on the training dummies in the capital city. Most people think they have a good build until they actually see the DPS meter.
First, check your "Haste" breakpoints. You want to see if adding one more point of "Haste" actually reduces your cast time or if you’ve hit a plateau. Usually, the breakpoints are at 15%, 30%, and 45%. If you’re at 28%, find a way to get that extra 2%. It makes a world of difference in how the character feels.
Next, look at your "Elemental Penetration." If you have zero, you're losing half your damage against armored enemies. Get at least 15% through your talent tree or weapon gems.
Finally, practice the "Crescent Swap." This is when you switch between your primary and secondary weapons mid-combo to keep your buffs active. It’s the hallmark of a pro player. It’s what separates the people who complain about the difficulty from the people who are speedrunning the content.
Check your gear for "Dead Stats." If you have "Mana Regen" on three pieces of gear, you're over-capped. Swap one of those out for "Area of Effect" size. Bigger hits mean more marks applied, which means more explosions. It’s a simple chain reaction.
Go to the vendor, buy some "Reforging Stones," and start rolling off those useless stats. Your Lune Act 2 build will thank you. Get out there and start clearing. The loot isn't going to find itself, and that vault isn't getting any easier.
