Strategy

In this Boss fight, you don’t battle the Boss directly; its health bar will go down every time you defeat one of the Hydro Mimics.

The Hydro Mimics are made of Pure Hydro, so they are immune to the element, and depending on the kind of Mimic, some are weaker to certain elements.

Trio Mimics appear on the corners of the Arena; use a ranged character, as Crane Mimics jump out of reach if you get too close, and the Flying Mimics stay too high for regular attacks.

Duo Mimics appear in the center of the Arena; they move a lot, and their attacks are annoying, but you can Freeze them to make them stop.

Solo Mimics appear on the edges of the Arena; these will explode once defeated, so run away as you do the last hit.

The Arena is Special in that it is always wet, so using Electro will electrify the floor, and the fact that Rhodeia sometimes sinks some sections.

When fighting the Hydro Mimics, if you take too long, the water under you will start rippling and then cause a ton of damage; you can dodge it if you run at the very last second.

Every few waves Rhodeia will sink one of the platforms, the center one will never sink; it might already be sunk before the fight starts, but it is due to a bug, it will fix itself if you reset the game.

Weak Point

This Boss has no weak point, but each kind of Mimic is weaker to certain elements.

Trio Mimics are weaker to Electro attacks.

Duo Mimics are weak to Cryo or Pyro depending on their appearance; if they look like a Duck or a Crab, they are weaker to Cryo; if they look like a Squirrel or a Boar, they are Weaker to Pyro.

Solo Mimics appear on the edges of the Arena, these are weaker to Geo attacks.
