The **Aquatic Weapon** in *Abyssus* is tied to the **Secret Pond** event—a hidden challenge many players overlook. This weapon, known as the Fish Deity’s Gun, isn’t part of the main storyline and requires completing the Mystery of the Pond quest across multiple runs to unlock permanently.
How to Unlock the Aquatic Weapon
1. Defeat the Three Miniboss Variants
In Act 4, Stage 1, three unique minibosses appear before the Royal Abyss—only one per run. Each corresponds to a statue in the Pregame Lobby fountain. Defeating one activates its statue. All three must be defeated across separate runs to awaken the pond.
2. Activate the Secret Pond
When all statues emit water, return to the lobby. Behind the seaside waterfall lies a hidden room. Wait until the pond inside fills completely to trigger the Fish Deity encounter.
3. Claim the Reward
Defeat the Fish Deity to unlock the Aquatic Weapon for all future runs.
Pro Tips
- Use modifiers to force all three minibosses to spawn in one run.
- Track activated statues to avoid redundancy.
- Prioritize faster minibosses (e.g., frog variant) to save resources.
