You've spent forty hours in Ancient Greece. You’ve climbed Zeus’s lightning bolt, kicked a few dozen soldiers off cliffs, and realized that your family tree is basically a wildfire. But then the game drops the Cult of Kosmos on you. It’s a massive, sprawling conspiracy that requires you to hunt down 44 different individuals across a map that is, frankly, too big for its own good. If you're looking for Assassin's Creed Odyssey cultist locations, you've probably realized that the game doesn't just hand them to you. It wants you to work for it.
Hunting the Cult is the real backbone of the game. It’s what turns Odyssey from a standard mercenary simulator into a Greek tragedy. Some of these guys are easy. You'll stumble over them while doing main quests. Others? They are hidden behind obscure side quests, tucked away in underwater shipwrecks, or masquerading as helpful NPCs. It’s a grind, but a satisfying one because every kill brings you closer to that sweet, sweet Ghost of Kosmos reveal and the legendary Deimos set.
The Eyes of Kosmos: Your First Real Test
This branch is mostly located around Attika and Phokis. It’s the "tutorial" branch, but don't let that fool you. Elpenor is the one everyone remembers because he’s part of the main story. You find him in Phokis, specifically at the Temple of Snake. You can't miss him; the game basically forces the confrontation.
Then there’s Sotera. She’s chilling at the Port of Nisaia in Megaris. She isn't a fighter. If you sneak up on her, you can end it in one hit. Honestly, the hardest part about Sotera is just getting to the docks without alerting every guard in the province. The Midas is in Argos. He’s standing right in the open near the Temple of Poseidon. No complex mystery here—just a man and his gold.
Hermippos is a bit trickier. You actually have to do the "Free Speech" side quest in Athens to reveal him. He’s at the Temple of Hephaistos. Finally, there's The Master. He is arguably the most annoying because he only appears during the "A Life's Worth" questline in Attika. If you haven't done the pre-requisite Socrates missions, you'll never find him. He’s at the Lavrio Silver Mine. Kill him, and you get a piece of the Spartan Renegade set.
Why Some Cultists Just Won't Show Up
It’s frustrating. You have the clue, you know the general area, but the "Reveal" button is greyed out. This happens a lot with the Silver Vein and Gods of the Aegean Sea branches.
Take The Griffin, for example. He’s on the island of Kythera. But you can't just find him at the beach. You have to kill a completely different mercenary first to get the clue. This is a recurring theme in Odyssey. The game forces a web of dependencies. If you're missing a cultist, check your mercenaries tab. If you see a mercenary with a greyed-out icon or a hint about a "Cultist Clue," go kill them. It’s the only way.
The sea-based cultists are another beast entirely. Asterion is usually sailing between Skyros and Andros. His ship has a giant crown on the sail. You have to sink it. There is no "hidden location" for him; the ocean is his home. Sokos only shows up during the Melos Conquest Battle. You have to lower the nation power of Melos until a battle is available, then choose a side. During the chaos of the naval fight, his ship will spawn. If you skip the battle, you skip the kill.
Delving into the Delian League and Peloponnesian League
The Delian League members are mostly politicians and thugs scattered across the islands. Podarkes is a big one. You find him on Mykonos, but you have to play through the "Hades, Meet Podarkes" quest. This is one of the best side stories in the game, involving a rebellion and a romance option. It feels less like a checklist and more like a real piece of the world.
Over in the Peloponnesian League, things get more martial. Monger is in Korinth. You deal with him in the main quest. You get a choice of how to kill him—publicly in the theater or privately in a cave. Choosing the cave makes your life easier later with another character named Brasidas. Silanos of Paros is another naval target. You'll run into him during the "United Front" quest.
Then there is Lagos the Archon. This guy is fascinating because he’s the only cultist you can actually convince to leave the Cult. You find him in Arkadia. If you spared the Monger in the cave and did the right side quests for Brasidas, you can talk Lagos down. It’s a rare moment of nuance in a game that usually rewards you for stabbing everyone in the neck.
The Most Obscure Assassin's Creed Odyssey Cultist Locations
Some of these people are just jerks to find. Diona is a prime example. She’s on Kythera. You do a whole series of quests for her, only to find out she has a twin sister. You have to pick the right one to kill in a dialogue scene. If you pick wrong, the real cultist escapes (temporarily) and you kill an innocent woman. Pay attention to the dialogue; the real Diona is the one who sounds like a sociopath.
Melite is hidden in Pephka, specifically at Typhon's Revenge. He’s just sitting in a house. But getting the clue requires you to kill another cultist first. Harpalos is in Keos, hiding in a cave called the Deep Cave of Ares. It’s dark, it’s damp, and it’s filled with level 50 guards if you go there too early.
Worshippers of the Bloodline
These folks are obsessed with the lineage of the Eagle Bearer.
- Zoisme: Found in the Wilds of Isthmia in Malis. She’s at a wolf den. Fitting.
- Chrysis: You meet her in Argolis. She tries to burn a baby. If you save the baby, she runs away. You then have to find her later via a side quest called "Death Comes for Us All."
- Diona: Mentioned above, Kythera Island.
- Melite: Messara, Kresilas's Residence.
- Belos the Beast: He’s a champion in the Arena. You have to fight your way through the ranks in Pephka to get to him.
Heroes of the Cult: The Heavy Hitters
These are the fighters. Okytos the Great is at the Sanctuary of Sounion in Attika. He’s usually surrounded by about six guards, so don't just charge in. Deianeira is in Boeotia. You can find her wandering the hills or during the "Fall of Deianeira" quest. She’s tough. She hits like a truck.
Pallas the Silencer is another one tied to a Conquest Battle. You need to fight for Athens in the Achaia region. He won't show up otherwise. This is a common pitfall for players who just clear icons on the map. Some cultists are locked behind the geopolitical mechanics of the game. If a region isn't in "Vulnerable" status, you aren't finding Pallas.
The Sage Problem
Each branch has a Sage. These are the leaders. You can't unmask a Sage until you’ve killed every single subordinate in their branch.
- Exekias the Legend: He’s the Sage of the Heroes of the Cult. He is also the #1 ranked mercenary in the game. He will hunt you. It’s a great dynamic—the hunter becoming the hunted.
- Iokaste the Seer: Sage of the Worshippers of the Bloodline. She’s at the Anavato Ruins in Chios.
- Gorgophon: Sage of the Silver Vein. Found in the Achaia region at the Fort of Olouros.
- Kodros the Fate: Sage of the Delian League. He’s the leader of Lesbos.
Finding these sages is less about exploration and more about completion. You finish the list, you get the Sage. You kill the Sages, you get the clues for the Ghost.
Strategic Tips for Your Hunt
Don't try to do this all at once. You will burn out. Ancient Greece is gorgeous, but the travel time between the volcanic islands and the snowy peaks of Lakonia is significant.
Instead, integrate the hunt into your exploration. If you’re in a new city, check the local message board. Often, the "bounty" missions or local side quests (the gold exclamation points) lead directly to a cultist clue or the cultist themselves.
Always loot every body. I can't stress this enough. Many clues are held by random captains in forts who have nothing to do with the Cult on the surface. If you skip looting, you're just making the endgame harder for yourself.
Also, upgrade your Spear of Leonidas. You need those cultist shards to reach higher tiers of abilities. If you find yourself struggling with combat, it’s probably because you haven't killed enough cultists to unlock the best versions of your skills. The game creates a loop: kill cultists to get stronger, use that strength to kill harder cultists.
Actionable Steps for Completion
If you're stuck at 43/44 cultists, here is exactly what you need to do:
- Check the Arena: If you haven't beaten the level 50 champion, you might be missing Belos.
- Clear the Quests: Specifically "A Life's Worth" (Attika), "Death Comes for Us All" (Argolis), and "I, Diona" (Kythera).
- Go Deep Sea Diving: There are clues in shipwrecks off the coast of Messara and near the island of Thera.
- Buy the Clue: There is literally a vendor in Korinth who sells a cultist clue for a few drachmae. It’s for the cultist Phoebe's killer (basically).
- Trigger Conquest Battles: If you're missing a Silver Vein or Delian League member, start weakening Achaia or Melos.
Hunting the Cult of Kosmos is a long game. It’s designed to span the entire length of your playthrough. Once you’ve cleared the map and gathered the fragments, head back to the Sanctuary of Delphi. The conclusion of this arc is one of the more philosophical moments in the franchise, dealing with the balance of order and chaos. It makes the dozens of hours spent sailing and stabbing feel like they actually meant something in the grand history of the Assassins and Templars.
