Your ship's ready

It can now go underwater. The advantage in underwater movement is that you don't get attacked.

Be sure to warp to Parcelyte and go to this underwater cave right below the town.

You'll find a Capsule Monster there

Go to Barnan and you'll learn that the entrance to the Shrine collapsed

You can access it through an underwater passage though

You'll surface here.

This is the boss of the Shrine. He's pretty annoying since he often does an attack that strikes the whole party : Doomcry. It either lightly damages your characters or kills them instantly. It can kill more than 1 character at a time. Valor and anti-undead/holy weapons and attacks are a must here.

You'll find Iris in Barnan once you come back.
