Saros Boss Guide — Attack Patterns, Weaknesses, and Kill Strategies for All 5 Bosses

Saros has five major bosses and they're all completely different fights. Not just visually. The mechanics shift so dramatically between each one that whatever worked on the last boss probably won't work on the next. I've died to every single one of these multiple times before figuring them out. Honestly some of those deaths were just me being stubborn about my loadout.

Warden of Ash — Biome One

The Warden is a tutorial boss wearing a real boss's health bar. It teaches you parrying. That's its entire purpose. If you can parry consistently you'll kill it in under three minutes.

Attack patterns. Phase one it fires sweeping horizontal laser beams. The beam sweeps left to right, pauses, then right to left. The parry window is when the beam emitter flashes white about half a second before firing. Each successful parry reflects the beam back and stuns the boss.

Phase two summons three corrupted colonists from the sides. They're normal enemies but they distract you from the boss. The Warden keeps firing lasers while adds are up. Kill the adds quickly. The sidearm is actually better here than your primary because it one-shots the colonists with headshots.

Phase three adds homing orbs on top of the lasers. The orbs track for about four seconds then explode. Don't try to parry the orbs. You can't. Dodge them and focus on parrying the lasers.

Weapon I recommend. The scatter-type weapons work poorly here because the boss's weak point is its chest core which is a small target. Take a precision weapon. Even the basic pistol is fine if you've upgraded its damage once.

Conservator — Biome Two

Completely different fight from the Warden. The Conservator doesn't fire projectiles you can parry. Instead it uses ground slams, vine attacks, and area denial.

Ground slam. The boss raises both arms and smashes the ground. A shockwave radiates outward. You jump over it. Timing is lenient. Just don't be mid-dodge when the slam hits because you can't jump out of a dodge.

Vine projectiles. The Conservator fires three seeking vines that travel along the ground toward you. Shoot them before they reach you. Any weapon works. Each vine takes about three shots from a basic weapon.

Poison pools. At sixty percent health the Conservator starts vomiting poison pools into the arena. They persist for about twenty seconds and do massive damage if you stand in them. The arena gets crowded fast. Stay near the edges where the pools spawn less frequently.

Grapple points appear after the first poison pool phase. Use them to reposition quickly. The boss has poor vertical tracking so being airborne makes you harder to hit.

Drowned Oracle — Biome Three

This is the fight where most players hit a wall. The Oracle's clone mechanic is disorienting and the one-shot beam in phase two demands specific counterplay.

At full health the Oracle summons four clones. Five identical figures all firing projectile patterns. Only the real one takes damage. The real Oracle has a subtle golden outline around its head. It's hard to see in the chaos but once you know to look for it the fight becomes manageable.

The clones fire the same patterns as the real Oracle but they're offset by about half a second. This creates overlapping bullet patterns that look impossible to dodge. They're not. The gaps are always there. Move toward the real Oracle through the gaps rather than trying to avoid everything.

At forty percent health the Oracle drops the clone mechanic entirely. Now it channels a massive beam attack. The beam takes about four seconds to charge and during that charge the Oracle is completely vulnerable. Dump everything you have into it. If you break the damage threshold the beam cancels.

If you can't hit the damage threshold the beam fires. It sweeps the entire arena. The only safe spots are behind the stone pillars at the edges. The beam destroys a pillar each time. Three pillars total. If you haven't killed the Oracle by the time all pillars are gone, the next beam is guaranteed death.

This fight rewards aggressive weapon loadouts. High rate of fire with decent damage. The charged beam phase is a pure DPS check. I could go on about specific damage thresholds for each weapon type but you kinda just need to test what works with your build.

Warlord — Biome Four

The Warlord is a positioning fight. It has a rotating directional shield that blocks all damage from the front. You need to constantly circle around to the unprotected side.

The shield rotates slowly clockwise. Follow it. When you're on the unshielded side, fire until the shield catches up then reposition. The Warlord also does a shield bash that covers about a third of the arena. It has a clear windup. The boss plants its feet and leans back. Dodge sideways.

At fifty percent health the Warlord summons two shield-bearing adds. They work exactly like the regular shield enemies from biome four. Parry them to expose weak points or use combat grapple if you have it. Killing the adds is top priority. They'll body-block your shots on the Warlord and their shield bashes overlap with the boss's attacks.

The Warlord's enrage at twenty percent health increases shield rotation speed. Now it rotates fast enough that your damage windows are about one and a half seconds. Burst weapons shine here. Shotgun-equivalents work great. Anything with a charge time is painful.

First Overlord — Biome Five

Four phases. Each phase stacks on top of the previous ones. The first Overlord is the longest boss fight in the game by a significant margin.

Phase one is projectile patterns. Orbiting bullet rings, expanding circles, aimed bursts. Standard stuff I guess but the projectile density is higher than anything before. Shield parry the aimed bursts. They're the ones that track you. The pattern attacks have static trajectories so learn the safe zones.

Phase two adds melee rushes. The Overlord teleports to a corner, charges across the arena in a straight line, and does a sweeping melee attack at the end. The charge is too fast to dodge sideways. Dodge toward and through the boss. The melee swing at the end has a half-second delay. You can get a few shots in during the recovery.

Phase three introduces corruption zones. They spread from the Overlord's position and expand over time. If two zones touch, they merge and the merged zone ticks damage faster. Keep the Overlord moving. Kite it around the arena perimeter.

Phase four is everything at once with faster projectile speed. The corruption zones spread faster and the melee charges happen more frequently. The arena feels tiny by this point. This is where having an area burst ability is invaluable. Use it to clear corruption pools near the center so you have room to maneuver.

At ten percent health the Overlord starts a final charging animation. This is the trigger for the true ending path. If you've collected all crew logs and exhausted dialogue in The Passage, interact with the Overlord instead of shooting it. If you haven't met those requirements, just finish the fight normally and come back on another run.
