Gear up before the abyss grinds you down
Luna Abyss throws its first real test at you early, and the Celebrant of Mani is exactly the kind of fight that separates players who understand the game's rhythm from those who don't. Pair that boss encounter with four weapon upgrades scattered across the game's progression, and you have two things that genuinely change how combat feels from the mid-game onward. This guide covers both: where to find every upgrade and how to survive the Celebrant of Mani without losing your mind to the bullet patterns.

What are the four weapon upgrades in Luna Abyss?
There are exactly 4 weapon upgrades to collect, each tied to one of the story weapons you unlock as you progress. None of them are random drops. They sit in specific spots along the upgrade path, which means you can miss them by rushing the objective marker. The four weapons with upgrades are:
- Scout Rifle — fast, accurate, reliable against standard enemies throughout the whole game
- Shieldbreaker — heavy shotgun-style burst damage, best against close-range and shielded targets
- Monarch's Lance — precision weapon for distance shots and removing dangerous enemies from crowded fights
- Atom Splitter — explosive weapon effective against large enemies and grouped targets
Collecting all four before you hit the harder encounters makes a real difference. The combat in Luna Abyss regularly forces fast weapon swaps between shielded enemies, flying targets, and dense bullet patterns. Having every weapon performing at its upgraded state removes the feeling that you're underpowered when those situations stack.
The Atom Splitter upgrade comes last in the progression sequence. Don't burn time searching for it early. Focus on the Scout Rifle upgrade first since it's the weapon you'll use most often in the opening sections.
How to get every weapon upgrade
Scout Rifle upgrade
The Scout Rifle upgrade is the first one you'll encounter. Proceed down the upgrade path and slow down before you reach the early upgrade spot. The item is placed off the main route, not directly on it, so players who follow the objective arrow without checking the sides will walk past it. Look left and right of the path rather than straight ahead.
Shieldbreaker upgrade
Continue past the Scout Rifle upgrade area and into the next upgrade section. Before leaving, check the corners and side spaces near the main route. The Shieldbreaker upgrade doesn't require deep exploration, but it does reward players who pause and look around rather than pushing forward immediately. The Shieldbreaker itself works like a heavy shotgun, so this upgrade matters most when you're dealing with enemies that push close or carry shields.

Monarch's Lance upgrade
Progress to the section where the Monarch's Lance upgrade route opens. This upgrade is near the path connected to the weapon's progression, not hidden in an obscure location. Check the platform spaces around the marked route before moving on. Monarch's Lance handles precision long-range shots and focused damage against tougher targets, so upgrading it pays off whenever fights become crowded and you need to pick off a priority enemy quickly.
Don't skip platform spaces near upgrade routes. All four upgrades are positioned close enough to the main path that they're technically reachable without backtracking, but easy to miss if you're moving fast.
Atom Splitter upgrade
The Atom Splitter upgrade is the last of the four and appears after the others in the progression sequence. When you reach the final weapon upgrade area, check the path carefully before continuing deeper into the level. The Atom Splitter is the game's explosive option, which makes it the go-to choice for larger enemies and rooms where multiple targets cluster together. Once you pick this up, you have the full set.

How to beat the Celebrant of Mani
The Celebrant of Mani is an early boss fight in Luna Abyss, and it's designed to test whether you've absorbed the game's core movement logic. Damage output matters less here than pattern recognition. Players who try to push damage aggressively will take hits they didn't need to take.
What's the best weapon for this fight?
The Scout Rifle is the right call for the Celebrant of Mani encounter. It keeps you at mid-range, which is exactly where you want to be, and lets you land consistent damage without committing to a close-range position. The Shieldbreaker is too risky here because closing the distance exposes you to more projectiles. Stick with the Scout Rifle and use controlled bursts rather than sustained fire.
Don't stand still to aim for extended periods. The Celebrant of Mani punishes slow movement fast. Fire in short bursts, then return to moving before the next projectile wave starts.
How do you dodge the bullet patterns?
The key shift most players need to make is moving sideways instead of backing straight away from the boss. Retreating in a straight line narrows your escape options and makes bullet-hell patterns harder to navigate. Circling the arena keeps space open on multiple sides.
Watch the gaps between projectiles, not the projectiles themselves. This sounds counterintuitive, but focusing on the safe spaces rather than the threats makes it much easier to slide through openings without panicking. Staying near the edges of the arena also helps because the middle gives you fewer directions to escape when patterns overlap.
Dodge the gaps, not the shots
What's the core strategy to win?
Here's the approach that works: keep the boss at mid-range, fire during the pauses between attack patterns, and retreat before the next wave launches. If the fight opens a short close-range window, take a few shots and leave immediately. Greedy damage is the fastest way to lose health in this encounter.
If smaller enemies appear during the fight, don't ignore them but don't prioritize them over survival either. Weaken them first, then use the healing opportunity if the boss is between attacks. Healing at the wrong moment still leaves you exposed, so only commit to it when you're confident the boss isn't about to launch another pattern.
Common mistakes to avoid
- Watching the boss health bar instead of the projectile field
- Standing in the center of the arena for too long
- Firing continuously instead of using burst windows
- Healing during active attack phases rather than between patterns
- Backing straight away from the boss instead of circling
Why getting all upgrades before harder fights matters
Luna Abyss belongs to a genre of shooter games where weapon flexibility is as important as movement skill. The four upgrades don't just add numbers to your weapons. They make each weapon feel like it belongs in its role. The Shieldbreaker becomes a reliable answer to shielded enemies rather than a situational tool. The Atom Splitter turns crowded combat rooms from stressful into manageable. Getting all four early means you're building good habits around weapon swapping rather than leaning on whichever gun you're most comfortable with.
