Metamorpha morph into four type of monsters (Behemoth, Blue Dragon, White Dragon, Ahriman). They are a consistent source of Perseus Arrows (the strongest arrows in the game). They can only be fought during Rosa's trial, and fighting them reduces the amount of time the player has to finish the trial in its entirety.
[view·edit·purge]Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a change in its body structure through cell growth and differentiation. Some insects, amphibians, molluscs, crustaceans, cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually accompanied by a change of habitat or behavior.
