Elysium Order: All 5 Ostraka Locations and Riddle Solutions

In Elysium Order, the Ostraka puzzles are among the most rewarding side activities, offering unique engravings that provide permanent stat enhancements to your heroines' equipment. Unlike standard gear drops, these engravings are essential for min-maxing your squad for high-level supernatural anomaly encounters. To solve these, you must first locate the Ostraka tablet—a document containing a cryptic riddle—and then travel to the specific environmental landmark described in the text to finalize the interaction.

This guide details the exact locations of all five tablets and the corresponding solutions to help you optimize your squad’s build without wasting time on trial-and-error exploration.

1. The "Bottomless" Ostraka

The "Bottomless" Ostraka is tucked away in the Ruin of Rhadamanthos. To retrieve it, focus your search on the lower, more dilapidated tiers of the ruins. The architecture here is crumbly, and the tablet is resting on a stone plinth near a collapsed archway.

• The Riddle Solution: Once you have the tablet, travel to the Sunken Grave at the southernmost tip of the Elysium map. You are looking for a water-logged, partially submerged ruin. Interact with the altar located inside the water to trigger the completion and claim your first permanent engraving.

2. The "A Specific Taste" Riddle

This tablet is located in the vicinity of Pheneos Village. It is hidden inside a luxury residential structure perched on the hillside overlooking the main valley. You will need to climb the exterior to reach the second-floor balcony where the tablet sits.

• The Riddle Solution: The riddle points toward the nectar-producing agricultural zones. Head east of the village to the large, golden-hued terrace gardens. In the very center of these crops, you will find a small, ornate altar. Interacting with this altar solves the riddle and grants you a powerful elemental damage boost engraving for your weapons.

3. The "Tough Luck" Tablet

The "Tough Luck" Ostraka is located in the rugged mountainous terrain near the Deukalion’s Heritage waypoint. The tablet rests on a high, exposed cliffside ledge. Be prepared for a brief skirmish, as this area is often patrolled by sentries tasked with guarding the high-ground vantage points.

• The Riddle Solution: Your destination is the massive titan statue looming over the northern sector of the region. You must climb to the very top of the statue. The interaction point is located on the head of the titan; reaching it provides the solution and completes this challenging puzzle.

4. The "Turning Tides" Ostraka

Finding this tablet requires infiltrating the Iphigenia’s Refrain fortress. Due to the high density of enemies, we recommend using stealth tactics or high-mobility heroines to bypass the guards. The tablet is located in the inner sanctum of the central fortification.

• The Riddle Solution: After securing the tablet, travel to the extreme edge of the map where the cliffs meet the coastline. Look for a small, isolated boat moored near the jagged rocks. Interacting with the boat triggers the solve, rewarding you with an engraving focused on defensive resistance.

5. The "Doing Time" Ostraka

The final Ostraka, "Doing Time," is hidden within the administrative district of the main city center. Look for the most prominent, grand building in the plaza; the tablet is located on a balcony on the second floor, accessible by jumping from nearby roof structures.

• The Riddle Solution: Navigate to the prison cells located on the outskirts of the city. Locate the specific cell mentioned in the riddle text. Interacting with the cell door or the interior stone bench completes the final Ostraka challenge, unlocking your last unique engraving.

Why Ostraka Engravings Are Essential

In Elysium Order, equipment stats are the primary method of differentiating your build. While base gear provides raw defense and attack power, the engravings unlocked by solving Ostraka puzzles allow you to specialize your heroines. For example, if you are struggling against specific supernatural anomalies that utilize elemental damage, the resistances gained from these engravings can be the difference between a successful mission and a squad wipe.

Strategy Tip: You do not need to apply these engravings immediately upon finding them. Visit any blacksmith or equipment station to apply them to your favorite gear. Note that engravings are not passive traits; they must be equipped to a specific slot on your armor or weapons to take effect.

Expert Tips for Efficient Hunting

• Unlock Waypoints First: The map in Elysium Order is highly vertical. Before hunting for these items, spend time activating fast-travel waypoints to minimize travel time between the tablet locations and their respective solutions.
• Utilize Map Markers: If you are struggling to find a specific tablet, use the proximity scan feature. The game will provide a directional pulse when you are within a certain radius of the collectible, which is invaluable for tablets hidden inside dense city architecture.
• Squad Composition: If you are tackling these in high-level zones, bring a squad capable of stealth or high-damage single-target strikes. Many Ostraka tablets are guarded by elite sentries that can easily overwhelm a glass-cannon build if you are caught out of position.
• Prioritization: We recommend completing these puzzles early in your progression. The bonuses they provide are cumulative and will make the mid-game boss battles significantly more manageable as the difficulty of the anomalies ramps up.

By systematically clearing these five Ostraka, you ensure your squad is equipped with the best possible statistical advantages, allowing you to focus on unraveling the deeper conspiracies hidden within the world of Elysium Order.
