Saros Best Weapons: Complete Soltari vs Carcosan Arsenal Breakdown (2026)

I have been playing Saros almost nonstop since launch week, and after roughly 65 hours across dozens of failed runs and a handful of successful ones, I can confidently say that your weapon choice matters more here than in any Housemarque game before it. The gap between a mediocre loadout and the right one is the difference between clearing the Vault of Echoes and getting flattened on the second biome.

In this guide, I break down every weapon in both the Soltari and Carcosan arsenals, rank them based on real testing, and explain which ones pair best with the shield system’s Absorb, Power, and Parry mechanics. Whether you prefer aggressive rushing or careful defensive play, there is a weapon here that fits your style.

How Weapons Work in Saros

Before jumping into rankings, you need to understand how Saros structures its weapon system. Unlike Returnal, which dropped weapons as random pickups with escalating proficiency, Saros splits its entire arsenal into two distinct factions: the Soltari and the Carcosan. Each faction contains six primary weapons, and every weapon has its own trait tree that unlocks permanently through repeated use.

If you are brand new to the game, our Saros beginner tips guide covers the basics of combat flow and resource management before you dive into weapon optimization.

Soltari vs Carcosan: What Defines Each Arsenal

Soltari weapons lean toward precision, sustained energy output, and controlled damage delivery. They reward players who maintain distance and aim deliberately. Visually, they pulse with warm amber and white light, and their audio feedback is clean and sharp.

Carcosan weapons are the opposite end of the spectrum. They favor close-to-mid range aggression, area saturation, and chaotic burst damage. Their organic, almost living aesthetic comes with heavier recoil and wider spread patterns, but the raw damage ceiling is noticeably higher.

Weapon Rarity and Traits

Every weapon drops in one of four rarity tiers: Standard, Enhanced, Volatile, and Ascended. Higher rarity unlocks additional trait slots, and traits are where the real power scaling lives. Traits like Overcharge Rounds, Siphon Strike, and Entropic Bloom can fundamentally change how a weapon performs. Unlocking traits is tied to the permanent progression system, so every run contributes even when you fail.

Every Soltari Weapon Ranked

I tested each Soltari weapon across multiple biomes, factoring in base DPS, trait potential, shield synergy, and how forgiving each one feels during high-pressure encounters. Here is how they stack up.

1. Soltari Lancer (S-Tier)

The Soltari Lancer is a precision beam weapon that delivers continuous focused damage as long as you hold the trigger. It starts strong, but once you unlock the Resonance Cascade trait, each sustained hit amplifies damage by roughly 8% per second. Against bosses with large exposed weak points, nothing in the entire game matches its single-target output.

I used the Lancer to solo the Architect on my first successful clear. The trick is pairing it with the Absorb shield mode, which lets you tank a hit, convert it to energy, and immediately dump that energy back through the beam. That feedback loop carried my entire run.

Best for: Boss fights, precision players, Absorb shield builds

2. Soltari Convergence Rifle (A-Tier)

This is the workhorse of the Soltari arsenal. The Convergence Rifle fires three-round bursts of energy bolts with tight grouping at mid range. It does not excel in any single category, but it has zero major weaknesses. The Phase Piercing trait lets bolts pass through the first enemy hit, which makes it surprisingly strong in hallway encounters where enemies line up.

If you are not sure what to grab, the Convergence Rifle is always a safe pick.

Best for: General use, mid-range combat, new players learning Soltari weapons

3. Soltari Arc Caster (A-Tier)

The Arc Caster fires chain-lightning projectiles that bounce between nearby enemies. Its single-target damage is mediocre, but against three or more grouped enemies it becomes one of the most efficient crowd-control tools in the game. The Volt Surge trait extends chain range by 40%, which is when this weapon truly comes alive.

I found it indispensable in the Crimson Threshold biome where smaller enemies swarm from multiple spawn points simultaneously.

Best for: Crowd control, mob-dense biomes, Power shield builds

4. Soltari Radiant Repeater (B-Tier)

A rapid-fire energy weapon with a very high rate of fire but low per-hit damage. The Radiant Repeater struggles against armored enemies unless you unlock Thermal Erosion, which strips armor over sustained fire. Without that trait, it feels underwhelming in later biomes.

It is fun to use and great for staggering enemies quickly, but the damage floor is too low for a serious endgame build unless you invest heavily in traits.

Best for: Early biomes, stagger-focused builds, players who prefer spray-and-pray

5. Soltari Dawnpiercer (B-Tier)

A semi-automatic heavy energy rifle with slow firing speed but high burst per shot. The Dawnpiercer hits hard, but the wind-up between shots leaves you vulnerable. I found myself eating damage between shots more often than I would like, especially against fast-moving Carcosan Wraiths.

With the Overcharge Rounds trait it can one-shot most standard enemies, but the risk-reward ratio keeps it out of the top tier.

Best for: Players with strong dodge timing, calculated playstyles

6. Soltari Nova Lens (C-Tier)

A charged shot weapon that requires holding the trigger before releasing a wide energy pulse. The Nova Lens has the highest single-shot damage of any Soltari weapon, but the charge time is painfully long. In a game this fast, standing still for 1.5 seconds to charge is a death sentence in most situations.

It works in very specific setups where you have the Parry shield timed perfectly to create safe windows, but that is an advanced strategy most players will not consistently execute.

Best for: Advanced players, Parry specialists only

Every Carcosan Weapon Ranked

The Carcosan arsenal trades precision for raw destructive power. These weapons reward aggressive positioning and close-quarters confidence. Here is how they rank after extensive testing.

1. Carcosan Riftcleaver (S-Tier)

The Carcosan Riftcleaver is a melee-hybrid weapon that fires short-range energy slashes. It has absurd burst damage at close range and its melee combo finisher triggers an AoE explosion that scales with the Entropic Bloom trait. This weapon single-handedly makes aggressive builds viable in every biome.

I ran Riftcleaver through three consecutive successful clears and it never felt underpowered. Pair it with Power shield for maximum offense. When you Absorb a hit and immediately chain into the Riftcleaver’s combo finisher, the resulting explosion damage is almost double what you would get normally.

Best for: Aggressive melee-hybrid builds, Power shield users, speedrunners

2. Carcosan Tendril Launcher (S-Tier)

The Tendril Launcher fires homing organic projectiles that seek enemies within a generous cone. The tracking is not perfect, but it is strong enough that you can fire while sprinting and dodge-rolling without losing much accuracy. The Parasitic Link trait adds a lifesteal effect on hit, which makes it arguably the most survivable weapon in the game.

This was my go-to comfort pick for learning new biomes. You can focus entirely on movement and let the tracking handle aim.

Best for: Survivability builds, biome exploration, players who struggle with aim under pressure

3. Carcosan Maw (A-Tier)

A close-range spread weapon that fires a burst of organic shrapnel. The Carcosan Maw is essentially a shotgun, and it feels incredible. Point-blank damage is devastating, and the Ravening Burst trait adds bonus damage when all pellets connect with a single target. Against large enemies and most bosses, this thing melts health bars.

The downside is range. If you cannot close distance safely, you are bringing a knife to a gun fight.

Best for: Close-range specialists, boss damage, Power shield all-in builds

4. Carcosan Spore Cannon (A-Tier)

This weapon fires lobbed projectiles that explode into lingering damage clouds on impact. The Spore Cannon excels at area denial and deals damage-over-time that stacks. The Fungal Propagation trait causes spore clouds to spread to nearby surfaces on kill, which creates chain reactions in tight spaces.

I found it extremely effective in the Sunken Archive biome where enemies funnel through narrow corridors.

Best for: Area denial, defensive play with Carcosan weapons, corridor encounters

5. Carcosan Void Eater (B-Tier)

A heavy explosive weapon that fires slow-moving projectiles with massive splash damage. The Void Eater has the highest raw damage per shot of any weapon in either arsenal, but the projectile speed is painfully slow and the reload time between shots is long.

When it connects, everything dies. When it misses, you are standing there reloading while three Wraiths close distance.

Best for: Calculated burst damage, combo setups, situational use

6. Carcosan Hollow Weaver (C-Tier)

A mid-range weapon that fires webs of energy in a cone pattern. The Hollow Weaver has an interesting slowing effect on enemies, but its damage output does not justify the utility in most scenarios. Enemies in Saros die to damage, not crowd control alone, and the Hollow Weaver simply does not kill fast enough.

Best for: Niche crowd-control setups, early biomes only

Best Saros Weapons by Playstyle

Choosing the right weapon depends on how you approach each run. Here is a quick breakdown by playstyle.

Aggressive Rushdown

Pick the Carcosan Riftcleaver with Power shield. Close distance, use Parry to create openings, and chain melee combos. This build clears biomes fast but punishes mistakes hard. If you enjoy the kind of high-risk combat that sets Saros apart from Returnal, this is the build to master.

Defensive and Methodical

The Soltari Lancer paired with Absorb shield lets you hang back, tank incoming projectiles, and pour sustained beam damage into priority targets. It is slower but extremely safe once you learn enemy attack patterns.

Speedrunning

Experienced runners are gravitating toward the Carcosan Riftcleaver and Carcosan Maw combo, swapping between them depending on encounter size. The burst damage of both weapons minimizes time spent in each room.

First-Time Clears

If you are pushing for your first full clear, grab the Carcosan Tendril Launcher for its homing projectiles and lifesteal. You can focus on learning boss patterns without worrying about perfect aim.

Weapon and Shield Synergies That Actually Work

The shield system in Saros is not just a defensive tool. It is a core part of your damage loop. Understanding which shield mode pairs with which weapon is the difference between good runs and great ones. Our full shield system breakdown covers the deeper mechanics, but here are the weapon pairings I found most effective.

Shield Mode	Best Weapon Pairing	Why It Works
Absorb	Soltari Lancer	Absorbed energy fuels beam amplification
Power	Carcosan Riftcleaver	Power charges boost melee combo finisher AoE
Parry	Soltari Nova Lens	Perfect Parry creates safe charge windows
Absorb	Carcosan Tendril Launcher	Absorbed energy + lifesteal creates near-infinite sustain
Power	Carcosan Maw	Power burst + point-blank shrapnel = instant kills

How to Unlock Every Weapon

Not all weapons are available from the start. Saros gates weapons behind its permanent progression system, which uses Eclipse Fragments earned at the end of each run. Here is the unlock order based on Fragment cost.

Weapon	Arsenal	Eclipse Fragment Cost	Unlock Requirement
Convergence Rifle	Soltari	Free	Available from start
Radiant Repeater	Soltari	Free	Available from start
Carcosan Maw	Carcosan	Free	Available from start
Hollow Weaver	Carcosan	Free	Available from start
Soltari Lancer	Soltari	120 Fragments	Clear Biome 2
Tendril Launcher	Carcosan	120 Fragments	Clear Biome 2
Arc Caster	Soltari	200 Fragments	Clear Biome 3
Spore Cannon	Carcosan	200 Fragments	Clear Biome 3
Dawnpiercer	Soltari	350 Fragments	Clear Biome 5
Void Eater	Carcosan	350 Fragments	Clear Biome 5
Nova Lens	Soltari	500 Fragments	Defeat final boss
Riftcleaver	Carcosan	500 Fragments	Defeat final boss

Tips I Learned After 60+ Hours of Weapon Testing

These are things I wish I knew earlier. They are not in any tutorial or loading screen tip.

• Trait leveling persists across runs. Even a bad weapon becomes usable once you max its traits. Do not ignore weapons you dislike early on because they might transform later.
• Swapping weapons mid-combo resets your damage multiplier. Commit to your combo string before switching.
• Carcosan weapons benefit more from the Power shield buff than Soltari weapons do. The flat damage boost matters more when your per-hit damage is already high.
• The Soltari Lancer’s beam does not trigger environmental hazards. You can fire through explosive pods without detonating them, which is a huge advantage in the Crimson Threshold.
• Always pick up weapons even if you do not plan to use them. Just holding a weapon for a few kills contributes to its trait unlock progress.
