How to destroy the Green Emerald Lake Seal in Vampire Survivors Tides of the Foscari DLC

As you run around the Lake Foscari stage added in the Vampire Survivors Tides of the Fosari DLC, you'll notice a large green emerald in the northeast, next to the giant lake. You'll need to break this to unlock a new stage, but it's not as simple as hitting it with any character. Here's how to destroy the Green Emerald Lake Seal in Vampire Survivors Tides of the Foscari DLC.

How to find the Emerald Seal in Vampire Survivors

To find the Seal of the Lake, head northeast from the starting point until you reach a maze. Take a right, up, right, up, left, down, left, and then up to exit out of the other side. From here, travel northeast again, and you'll reach the mysterious Green Emerald by Lake Foscari.

You need to break it, but you can't do it with just anyone: you need to play as Keitha Muort and have the Millionaire weapon evolution in order to smash the crystal. Once you have everything, simply approach the emerald, and it will shatter.

How to unlock Keitha Muort in Vampire Survivors

To unlock Keitha Muort, you need to evolve Eskizzibur into Legionnaire. Eskizzibur is Maruto Cuts' starting weapon, and to evolve it into Legionnaire, you need to max out Eskizzibur at level eight and get Armor to its max level of five.

Once Eskizzibur and Armor are both maxed out, open a Treasure Chest to trigger the evolution into Legionnaire and unlock Keitha Muort in Vampire Survivors.
