The map is a large underwater town with Sharken, Fish Wyverns, and a Kraken boss. Similar to Moraggo Desert Town, Aquanos features colored portals which allow players to quickly travel across key points of the large-sized map.
Two Seahorses and Snails are scattered across the map. They act similar to treasure chests. They can be "Pet" once per round, and drop mana. As well, they may heal the hero or deposit an item directly into the player's item box. The item's quality depends on the set difficulty.
- Complete the campaign version of the map to unlock a new skin for the Countess, the Mermaid Costume.
- The Seahorse pet is rewarded for reaching wave 20 in Survival Mode.
Not on console

- Retrieve all four Lost Eternia Shards (Purple, Blue, Yellow and Red) to unlock access to the Crystalline Dimension through a tavern portal.
