Metamorph can transform into more powerful versions of monsters and summons previously encountered. While transformed, its HP and MP remain the same, but its stats and abilities are different, as are the items that can be dropped. After attacking once, Metamorph will always revert to its original form, and then morph again on its next turn. While transformed, it has no elemental strengths or weaknesses, regardless of the type of monster it transforms into, but it also has no status immunities and cannot be controlled.
The possible transformations and their attacks are:
- Shiva: Blizzara
- Ifrit: Blaze
- Ramuh: Lightning
- Gaelicat: Cat Scratch
- Elf Toad: Pond's Chorus
- Wyvern: Breath Wing
- Enchanted Fan: Aeroga
- Crew Dust: Flash
- Zombie Dragon: Zombie Breath
There are four different possible encounters with Metamorph, each having three different monsters that Metamorph will randomly choose to transform into. The four encounter variations are:
- Shiva, Gaelicat, Elf Toad
- Ifrit, Wyvern, Enchanted Fan
- Ramuh, Crew Dust, Zombie Dragon
- Shiva, Ifrit, Ramuh
The most valuable transformation it has is the Enchanted Fan, since this transformation is the first opportunity the party has to learn the Blue Magic Aeroga.
The encounter in the Interdimensional Rift uses the Ramuh/Crew Dust/Zombie Dragon encounter.
The Metamorph is weak against Wind and Water so the Ninja's Water Scroll or the Blue Magics Aera and Aeroga with the Air Knife equipped will do large damage. Instant Death or fractional damage attacks work while Metamorph is transformed.
It is advised to fight Metamorphs until one drops a Staff of Light. This weapon can be used as an item to cast Holy and cannot be purchased or gained from any other monster, aside from the boss, Halicarnassus. It must be defeated in its original form for the Staff of Light to be dropped. If the player does miss this chance to encounter the Metamorph, it is possible to still encounter one in the Interdimensional Rift, but it is the rarest encounter in the area, and will be much more difficult to obtain the Staff of Light from at that point.
The easiest way to ensure the Metamorph is defeated while in its original state is to cast Berserk on it as soon as possible. This will force it to stop transforming and only use regular attacks. Berserk can be purchased in Moore before going to Ghido's Cave for 6,000 Gil.
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.
