Armored Core 6: How to get the Moonlight Sword in AC6

Nearly every FromSoftware game contains a Moonlight Sword or some variant of it, and Armored Core 6 is no different, hiding the legendary blade late in the game in Chapter 4, Mission 34: Reach The Coral Convergence. The only issue is it’s guarded by some of the fiercest enemies you’ll face.

Is the Moonlight Sword in AC6?

Short answer: Yes. The Moonlight Sword, known in-game as the IA-CO1W2: MOONLIGHT light wave blade is available in Armored Core 6. Bit of a mouthful that, think we’ll just call it the Moonlight Sword from now on.

What is the Moonlight Sword in AC6?

The Moonlight Sword is a pulse/laser sword that dishes out a two-hit combo and fires off slices of light that can hit enemies at close-to-medium range. It’s lightweight and doesn’t use too much energy, so it’s a pretty solid all-rounder if you favor melee weapons.

Where to find the Moonlight Sword in AC6

You can find it in the chapter four mission Reach the Coral Convergence. It’s under a bridge guarded by about six mechanized wheels that charge you, fire missiles at you, and spit molten fire. Oh, and that’s after you’ve fought off two powerful rival ACs and a bunch of MTs. To say it’s hard to reach would be an understatement.

How to beat V.VI Materlock and G3 Wu Huahai

At the start of the mission, you’ll fly over some ruined skyscrapers and face off against V.VI Materlock and G3 Wu Huahai. You can sit back and let them fight the PCA mechs to whittle down their health first, or you can charge down Materlock. You’ll want to focus on only one mech at a time for the easiest path to victory here.

For this mission, you’ll likely want to use bipedal legs to maintain speed and efficient maneuverability–06-041 MIND ALPHA is a great choice here. To dish out damage, I’d recommend dual linear rifles and dual missile launchers, preferably the Harris rifles and BML-G2/P05MLT-10s. Using these will stagger Materlock and quickly tear through her health.

After that, use the same strategy on Wu Huahai. On both, I’d recommend using your assault boost and boost kick to keep them close and get some extra ACS damage in so your missiles can rip through them. 

Moonlight Sword location in AC6

With those ACs and PCA mechs turned to scrap, it’s on to the Moonlight Sword. Simply proceed through the ruined city until you find a bridge. Get on it and expect an ambush by a huge wheel. Dodge out of the way, turn, and when it gets to the apex of its charge, hammer it with both salvos to take it out. Then, proceed to the end of the bridge and look down and to the left.

There you’ll see three of these same wheels guarding the part container. That’s where the Moonlight Sword is. You can try to avoid the enemies altogether by quickly dropping in, opening the container, and boosting away as fast as you can. But if you want to ensure you won’t be ambushed, it may actually be safer to try and take them on from a distance instead.

Stay in the air and use your missiles to take down one wheel in a surprise attack. Then get ready for a tense fight. These things are fast and hammer you with missiles in the air, and charge and spit fire at you when you’re on the ground. Your best bet is to stay on the roof of a ruined building and fire missiles at them.

There are about six in total, three are around other parts of the bridge and don’t attack until the fight starts, and they can easily overwhelm even the toughest AC. You’re already weak from the fight before, so take it slow and steady. Once they’re all dead, go down and claim the Moonlight Sword.

Now, all you have to do is progress through the rest of the city and beat the level’s boss: the Ibis Series CEL 240. You can’t use the Moonlight Sword until you collect it and finish the mission all in one go.

IB-01: CEL 240 is the hardest boss in the game. This boss is fast and overwhelming, so maneuverability is key.  The build I recommended is perfect for taking it out, but if you find yourself struggling, try swapping out the bipedal legs for a compact tank build using EL-TL-11 Fortaleza, which should allow you to still move at a comfortable pace while increasing your defense and carrying capacity for some heavier artillery.

You won’t be able to boost vertically as well, but the increased defense will hopefully let you take a few more hits than you otherwise could. Be sure your OS Tuning is optimized for damage reduction and output, and your FCS prioritizes medium-range firing. And after you think you’ve finally taken down the Ibis Series, get ready for phase two. Good luck, Raven. After all’s said and done, you’ll have an amazing melee weapon.

Is the Moonlight Sword in AC6 worth it?

If you like to keep a melee weapon on you, absolutely. It does great ACS and direct damage, and its pulses of light mean you can still hit enemies that are just slightly out of reach—something other melee weapons can’t do. It doesn’t hit as hard as the laser sword, and it doesn’t drag you to foes as well as the pulse sword, but its two-hit combo and its ranged slices of light make up for both of these shortfalls.
