The Relic Construct is one of two Companion pets added to Fisch in the May 30, 2026 Minor Update, and it stands out because you can tailor its buffs by choosing which relic you feed it. It looks like a stone golem covered in glowing blue runes, and it spawns at a single fixed location rather than from a hunt. The trade-off is that taming it is a chance-based action, so the relic you pick directly affects how likely the attempt is to succeed.
Where the Relic Construct spawns in Fisch
The Relic Construct only appears inside Keeper's Altar, walking along the outer edges of the area. It shows up more often during a Power Burst, and it can also be present during Sovereign Weather. Because the spawn is tied to those conditions, the fastest route is to be standing in the Altar when one of those events is active.
Step 1: Take a boat to the Statue of Sovereignty at GPS coordinates (20, 160, -1040). This is your entry point to the underground area.
Step 2: Enter the mine and ride the elevator down to Keeper's Altar. The Construct cannot be reached from the surface, so you must descend first.
Step 3: Wait near the edges of the Altar for the Relic Construct to spawn. Spawns are random, so a Power Burst greatly improves your odds of seeing one quickly.
Step 4: Walk up to it and feed it a relic. The relic you choose sets both your taming chance and the buff that relic unlocks once the Construct is high enough level.
Relic taming chances and buffs
Feeding a relic is how you both tame the Construct and assign its passive effects. Each relic has its own taming chance, and the stronger buffs require the Construct to reach a higher level before they activate. If you want the fastest guaranteed tame, a Sovereign Relic locks it in at 100%, but lower-tier relics are cheaper entry points if you are still leveling.
| Relic | Level required | Taming chance | Buff |
|---|---|---|---|
| Enchant Relic | 1 | 10% | +20% XP; also doubles catch rates for Enchant, Exalted, and Sovereign Relics |
| Exalted Relic | 3 | 25% | +10% Luck, +10% Resilience, +10% Fish Weight |
| Cosmic Relic | 5 | 40% | +3% Shiny, +3% Sparkling, +3% Forced Progress Speed |
| Invincible Relic | 6 | 40% | +100 Durability |
| Twisted Relic | 8 | 40% | +3% Progress every 2 seconds at 50% chance |
| Song of the Deep | 9 | 50% | +5% True Progress Speed |
| Sovereign Relic | 10 | 100% | +10% Sovereign chance, +5% Resilience, +5% Fish Weight, +1% Forced Progress Speed, +1% Shiny, +1% Sparkling, +10% XP, +3% Progress every 3 seconds at 25% chance |
The Construct also raises your chance to catch relics in general while it is equipped, which makes it easier to stock up on higher-tier relics for its upgrades. Note that the better buffs only switch on once the Construct meets the listed level, so an early Enchant Relic feed is mainly there to secure the companion and start the XP bonus.
How to confirm the tame worked
A successful feed claims the Relic Construct as your Companion, and it joins your pet roster. If the attempt fails, the chance was simply not met, since taming is probability-based for every relic except the Sovereign Relic. The most common reasons a tame does not happen are feeding a relic with a low taming chance, such as the 10% Enchant Relic, or trying to interact before the Construct has spawned. If you want certainty in a single attempt, use the Sovereign Relic at level 10.
Keep an eye on the active event as well. Outside of a Power Burst, the Construct can be slow to appear, so showing up during one cuts down the waiting and gets you straight to the feeding step.
