Saros Guide: How to Get Honorarium Sigils & Where to Use Them

You crack open a white container in the Desecrated Fortress, expecting a weapon or a solid artifact, and instead you pull out an Honorarium Sigil. The item description mentions a sealed chamber but gives you no map marker, no direction, nothing. An optional objective ticks up in the corner of your screen reading "Collect Sigils," and then the game just leaves you to figure it out. This is entirely intentional on Housemarque's part, designed to reward players who explore every corner of the biome rather than sprinting the main path.

The short version: you need 6 Honorarium Sigils to open all the gates in the Sealed Chamber, which sits deep in the Desecrated Fortress just before the boss fight against the Architect. The longer version involves knowing exactly where to look and how the biome's cycle system affects your progress.

Where to find Honorarium Sigils in the Desecrated Fortress

Sigils replace Carcosan keys in the Desecrated Fortress biome, so if you've played through earlier areas of Saros, you already know the general drill. The key difference here is that the Fortress uses a semi-procedural layout, meaning the white containers holding Sigils won't always appear in the exact same spots between cycles. That said, the rules for finding them stay consistent.

Honorarium Sigil pickup point

How many Sigils do you need?

The target number is 6 Sigils total, matching the 6 locked gates inside the Honorarium. The biome generally contains enough containers to hit that number if you clear every path, but missing even one side route can leave you a Sigil short at the door.

Where the containers actually spawn

Sigils are found in white containers on both main and side paths throughout the Fortress. A few reliable patterns to keep in mind:

• High ground first. Housemarque frequently places white containers on elevated pillars that require the Eclipse Threads ability to reach. Before leaving any large room, look up.
• Yellow barriers hide extras. Some side paths are blocked by yellow energy barriers. These often conceal additional containers. You can't pass them immediately, but clearing nearby enemies or finding a switch usually drops them.
• Nightmare Strand is a bonus source. You can also earn Sigils by completing the biome's Nightmare Strand, so take that on if you feel strong enough.
• Minimap discipline. Keep checking your minimap for unexplored corridors. The Fortress's white-and-grey colour palette makes containers easy to miss visually, so the map is your best tool.

How to reach the Sealed Chamber

The path to the Honorarium is gated behind a specific biome ability, which is why players often find their first Sigil well before they can actually use it.

Step 1: Unlock Eclipse Threads

You cannot reach the Sealed Chamber without the Eclipse Threads ability. This movement skill, obtained from the Desecrated Fortress's main progression path, lets you cross the glowing gaps and vertical shafts that block the route to the vault. Focus on the main story path until you acquire it before worrying about collecting every Sigil.

Step 2: Push deep past the Eclipse Threads unlock point

The Honorarium sits well past the area where you first gain Eclipse Threads. Keep pushing through the Fortress's main route after you unlock the ability.

Step 3: Find the large empty room with red lasers

The clearest landmark before the Sealed Chamber is a very large room with no enemies inside, frequently filled with red security lasers that deal significant damage. When you walk into a silent, enemy-free chamber crisscrossed with red beams, you're right on top of your destination. Navigate or dash through the lasers to reach the far exit.

Step 4: Drop into the hole

Immediately after exiting the laser room, there's a large hole in the floor. Don't look for a bridge or a ladder. Drop straight down. This transitions you into the sub-level of the Fortress, and your objective marker will update to "Open the Honorarium" as soon as you land.

What's behind each gate in the Honorarium?

Once you're standing in front of the Honorarium door, the number of Sigils you've collected determines how much of the vault you can access. Here's what each section contains:

The Power Augments behind the second set of doors are worth prioritising. These provide some of the most significant stat boosts available in the mid-game, which makes the Architect fight considerably more manageable. The Audio Log on the rightmost path is the main lore reward for completionists.

What if you don't have enough Sigils?

Running out of Sigils before you've opened every gate is the most common problem players hit in the Desecrated Fortress. The fix is straightforward once you understand how the cycle system works.

Since the Honorarium resets each run, treat any incomplete visit as reconnaissance. Note which side paths you skipped, which yellow barriers you couldn't pass, and roughly where the white containers appeared. On your next cycle, you can clear the Fortress much faster with Eclipse Threads already unlocked and a mental map of where the Sigils tend to spawn.

If you're just one Sigil short after reaching the vault, it's worth backtracking to any unexplored side paths before resigning yourself to a new cycle. The objective stays active, and with Eclipse Threads the Fortress moves quickly.
