What are Relic Powers?
Relics grant Relic Powers that you equip alongside your build. Some don't even consume a build slot. The headline example is Endless Search, dropped by the floor 100 boss, which makes undiscovered gadget parts easier to find — equip it while chasing those last few upgrades.
The 9 relics and where they hide
After the credits, three Hidden Ruins dungeons appear. Each one holds relic treasures that act as the key to the Bottomless Buffet. Clear each Hidden Ruins with all three tank types (Speed, Power, Tactical) and you net nine relics total — three ruins across three tanks. Each clear with a different tank yields a different relic, so you'll be revisiting the same ruins with swapped loadouts.
Relics unlock the Bottomless Buffet
Hold all nine and the Bottomless Buffet opens at the hole in the middle of the map where the Salmonarch was fought. This is the only gate — no relics, no Buffet. It's strictly endgame content: you can't touch it until the main story is finished and every Hidden Ruins relic is in your collection. For the boss that waits at floor 100, see the final boss page.
Relic Collection & 100% completion
For completionists, the full Relic Collection is 88 treasures total. True 100% also asks for all four endings (the True Ending requires Bottomless Buffet floor 100), every Adventure File and Compass, all dungeons on Super Spicy, all Gadgets, and max Bond with all three Deep Cut members. It's a long but well-signposted grind.
Frequently asked questions
How many relics are there?
Nine — three Hidden Ruins times three tank types. Clear each ruin with every tank to collect them all.
What do Relic Powers do?
They're passive bonuses equipped on top of your build. Some, like Endless Search, don't use a build slot, so they stack freely with everything else.
Why bother collecting them?
They're the sole key to the Bottomless Buffet, the game's endless endgame dungeon and the path to the True Ending.
