Atlantica Wiki

Hidden Repositorium is an event dungeon (it is only available during certain events) for players level 50 and above. It's located in Southeast Asia India. NPC Giant Quest Acong gives a repeatable quest to obtain a key. You can get 1 daily for free and pay more for each additional one.


  • Killing all monsters in the dungeon (240) awards 500 Malignant Shards (2021). If you don't clear, you get 150 Malignant Shards for every 150 monster slain.

Tip: to clear you need at least 2 players, possibly 3 (it can be done with 2, but that's cutting it really close).
