The Faceless One appears after you unlock the Obsidian Sanctum
The Faceless One is a boss encounter in Prominence 2 that you cannot fight until you have progressed far enough into the game. You will need to complete the main story up through the point where you unlock access to the Obsidian Sanctum — this happens after you defeat the Warden and collect all four Primordial Shards. Once you have access to that area, you can summon the boss by interacting with the ritual circle at the center of the Obsidian Sanctum.
The ritual circle will only set up if you have the Void Catalyst in your inventory. This is a key item you receive automatically during the story, so you do not need to hunt for it separately. When you approach the circle with the Void Catalyst, you will see a prompt to begin the ritual. Selecting this prompt will trigger a cutscene and then spawn the Faceless One for combat.
Key Takeaways
- You must reach the Obsidian Sanctum by defeating the Warden and collecting all four Primordial Shards before the Faceless One can be summoned.
- The Void Catalyst, which you receive during the main story, must be in your inventory to set up the ritual circle.
- The ritual circle is located at the center of the Obsidian Sanctum and will display an interaction prompt when you approach it with the required item.
- The Faceless One fight begins when ready after the ritual cutscene, so make sure your equipment is repaired and your consumables are stocked before interacting with the circle.
Preparing your character before the ritual
The Faceless One is one of the harder boss fights in Prominence 2, so preparation matters. Before you approach the ritual circle, visit the nearest merchant or your camp to repair all damaged equipment. Even small cracks in your armor or weapon durability will cost you health or damage output during the fight, and you cannot pause to repair mid-combat.
Stock up on healing consumables — potions, salves, and any food items that restore health. The Faceless One has a long fight with multiple phases, so bring more healing items than you think you will need. If you have access to any temporary buff potions (strength, defense, or resistance potions), this is a good time to use them. You can drink these right before you interact with the ritual circle, and they will carry into the boss fight.
Understanding the ritual circle mechanics
When you interact with the ritual circle, a short cutscene will play. During this cutscene, you cannot move or act — the game is showing you the Faceless One emerging. Let this play through without trying to skip it, because the game needs the full animation to load the boss properly. If you skip cutscenes, the fight may start with the boss in an unexpected position or with delayed attack patterns.
After the cutscene ends, you will be placed in the arena with the Faceless One. You will have a few seconds of invulnerability while the camera adjusts, so use this time to move to a safe distance and assess the arena layout. The Obsidian Sanctum arena is circular with pillars around the edges — these pillars can be used for cover during certain attacks.
What to do if the ritual circle does not set up
If you approach the ritual circle and see no interaction prompt, the most common reason is that you do not have the Void Catalyst in your inventory. Check your inventory screen to confirm the Void Catalyst is there. If it is not, you may have dropped it or left it in a storage chest. Retrace your steps to where you last remember having it, or check any camp storage you use regularly.
A second reason the circle might not set up is that you have not actually defeated the Warden yet. The game tracks story progress, and the Obsidian Sanctum only becomes accessible after that specific boss fight. If you are unsure whether you have defeated the Warden, check your quest log — it will show you which main story bosses you have completed. If the Warden is not listed as defeated, you need to find and fight that boss first.
If you have both the Void Catalyst and have defeated the Warden, but the circle still will not set up, try leaving the Obsidian Sanctum entirely and re-entering. Sometimes the game needs to reload the area. Save your game before you leave, then exit through the door you came in, wait a few seconds, and come back in.
Positioning yourself in the arena after summoning
The arena where the Faceless One spawns has a specific layout that affects how the fight plays out. The center of the arena is open space where the boss will appear. The edges have several stone pillars that provide partial cover. When the fight begins, do not stay in the center — move when ready to one of the pillars on the edge of the arena.
The Faceless One has ranged attacks that are easier to dodge if you have distance and cover. Standing near a pillar gives you something to move around if you need to break line of sight. The arena is large enough that you can circle around the pillars while the boss chases you, which gives you time to heal or reposition. Avoid backing into corners, because the boss can trap you there and land multiple hits before you can escape.
What happens after you summon the Faceless One
Once the Faceless One is summoned and the fight begins, you are committed to the encounter. You cannot leave the arena, pause the game, or call for help. The fight will continue until either you defeat the boss or you are defeated. If you die, you will respawn at the last checkpoint you passed, which is usually the entrance to the Obsidian Sanctum. You can then re-enter and summon the boss again — the Void Catalyst will still be in your inventory.
When you defeat the Faceless One, you will receive a large amount of experience points and a unique reward item specific to this boss. The arena will return to normal, and you can leave the Obsidian Sanctum. The boss does not respawn after you defeat it, so you only need to summon and fight it once per playthrough.
Frequently Asked Questions
Can I summon the Faceless One multiple times in one playthrough?
No. Once you defeat the Faceless One, the boss is gone for that playthrough. The ritual circle will no longer set up. If you want to fight the boss again, you will need to start a new game or load a save file from before you defeated it.
What level should I be before I try to summon this boss?
Most players find the Faceless One manageable at level 35 or higher, though the exact difficulty depends on your equipment and build. If you are getting defeated repeatedly, try leveling up a few more times or upgrading your gear before attempting the summoning again.
Do I need specific weapons or abilities to fight the Faceless One?
No specific weapon is required, but the boss is resistant to physical damage and takes more damage from elemental attacks. If you have access to fire or lightning abilities, those will be more effective than basic sword swings. Healing and defensive abilities are more important than raw damage output for this fight.
Can I leave the Obsidian Sanctum and come back to summon the boss later?
Yes. You do not have to summon the Faceless One when ready after unlocking the Obsidian Sanctum. You can explore other areas, level up, gather better equipment, and return whenever you feel ready. The ritual circle will remain inactive until you interact with it.
