AC Odyssey: Hephaistos Islands Loot Treasures & Ancient Stronghold Chests

The Hephaistos Islands have 17 Loot Treasures spread across 11 locations in Assassin’s Creed Odyssey. Each location below shows where the chests are, with a map and a screenshot for every one, including the Ancient Stronghold chest behind the locked door.

The Hephaistos Islands are made up of Lemnos and Thasos. The region has no Ancient Tablets, but the Ancient Stronghold holds its only Ainigmata Ostraka, Hungry for Misadventure, and the Abandoned Tomb on Lemnos gives you a free Ability Point.

It all began in the ’80s when I was just 7 years old. Starting with basic arcade games, I soon delved into titles like Loom and Monkey Island by Lucasarts. Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
