A hidden chamber has opened inside Elemental Island, and it turns the area into a cooperative fishing challenge built around the new Elemental Hydra. The Elemental Expansion adds Hydra’s Throne Room, 15 fish, a fresh spin pool, a new ability, and a three-headed Hydra pet.
Quick answer: Place the Fire, Ice, and Storm Elemental Crystals on their podiums inside Elemental Island to permanently unlock Hydra’s Throne Room, then bring at least three players, one per elemental zone, to activate the Elemental Hydra.
How to unlock Hydra’s Throne Room
Access is gated behind three crystals you slot into their matching podiums. Once all three are placed, the gate opens, and the area stays open for you from then on.


Elemental Hydra: The new Forgotten fish and its odds
The Elemental Hydra is a Forgotten Fish that only appears through teamwork. You need at least three players active at the same time, with one stationed in each elemental zone, to trigger a spawn attempt.
Adding more players improves your chances, scaling up to a maximum of 15 players. Balancing all three zones matters because it directly affects your shot at the rarest combination.
| Combination | Catch odds |
|---|---|
| Most Hydra combinations | 1 in 40,000,000 |
| 1 Fire + 1 Ice + 1 Storm (rarest) | 1 in 45,000,000 |
Note: Keeping the three zones evenly staffed is what pushes your group toward the 1 in 45,000,000 combination rather than the more common outcomes.

15 new fish exclusive to Hydra’s Throne Room
Fifteen fish have been added, and they only spawn inside Hydra’s Throne Room. They span Mythic, Legendary, and Epic rarities and are tied to the fire, ice, and storm elements, so completing the set means fishing across all three zones.
Elemental Spin rewards
A new spin pool holds the update’s standout rewards, including the Hydra pet and the new ability. The full list of possible items is below.
| Reward | Type |
|---|---|
| Hydra Fishing Pet | Pet |
| Elemental Convergence Ability | Ability |
| New Fishing Rod | Gear |
| New Boat | Transport |
| New Lantern | Cosmetic |
| New Halo | Cosmetic |

Elemental Convergence ability and Critical Catches
Elemental Convergence introduces Critical Catches to fishing. When you activate the ability, it raises the chance of triggering a Critical Catch while you fish.
Hydra Fishing Pet
The Hydra pet has three heads and does more than sit on your shoulder. With it equipped, the center head fishes alongside you, while the two outer heads apply a Forgotten Luck Pool to your fishing spot.
Quality of life and fixes
- Improved lighting when several equipment effects are active at the same time.
- Added more glitch prevention across Elemental Island.
Once the gate is open and three players hold their zones, a successful roll adds the Elemental Hydra to your catch, confirming the group hit one of the listed combinations. Falling short almost always comes down to fewer than three players or an empty elemental zone, so keep all three covered before every attempt.
