By killing this Silver Vein, you’ll be able to earn the Boots of Agamemnon. Note this cultist has a few guards around, so you’ll need to kill the guards along with The Chimera. Be sure to confirm the kill once The Chimera and her guards are dead.
The Centaur of Euboea
The third Silver Vein is The Centaur of Euboea. They are a Level 31 enemy that can be unlocked through The Serpent’s Lair. This Silver Vein is located in the Abandoned Mine, Mount Dirfi, Euboea. By killing this Silver Vein, you’ll be able to earn Agamemnon’s Waistband. Note that this cultist has guards posted outside the mine. You can sneak past them and into the mind, or you can take them out. Again, don’t forget to confirm the kill once The Centaur of Euboea is dead.
The Silver Griffin
The fourth Silver Vein is The Silver Griffin. They are a Level 31 enemy that can be unlocked by earning a clue called Slaver’s Gift. This Silver Vein is located on Prasonisia Island, Tavern Point, Mykonos. By killing this Silver Vein, you’ll be able to earn Agamemnon’s Body Armor. Note that the clue to find The Silver Griffin is located in the Silver Mine, which is part of the Silver Mountain region in Attika. There’s a Legendary Chest in the mind, and inside is the Slaver’s Gift clue.
Machaon the Feared
The fifth Silver Vein is Machaon the Feared. They are a Level 45 enemy that can be unlocked by earning a clue called Dead Man’s Note. This Silver Vein is located in the Patrai Military Shipyard, Mount Panachaikos, Achaia. By killing this Silver Vein, you’ll be able to earn Agamemnon’s Helmet. Note that the clue to find Machaon the Feared is located in Shipwreck Cove as part of the Scavenger’s Coast in Achaia. Dead Man’s Note can be found by looting a dead body sitting on a rock.
Polemon the Wise
The sixth and final Silver Vein is Polemon the Wise. They are a Level 50 enemy that can be unlocked by eliminating all of the other Silver Vein members. This Silver Vein is located in Teichos of Herakles, Erymanthos Peaks, Achaia. By killing this Silver Vein, you’ll be able to earn the Elysian Axe. Note that the best way to kill this Silver Vein is by using your bow and whittling away his health. We recommend Predator Shot and Ghost Arrows of Artemis as the most efficient ways to take out Polemon. Using this method, you can go after him even if you’ve yet to reach Level 50.
