|Other Information||Spherimorph is always weak against one element and absorbs the others (except Holy). Its weakness may change during battle.|
Spherimorph is a Gel-type fiend from Final Fantasy X, encountered in the Macalania Woods. After completing the trek through the woodland trails, Auron remembers something from his journey with Braska and Jecht, and hacks his way through an overgrown side path. Down the new path is a beautiful spring, the water used to create spheres. With no warning, the Spherimorph attacks the party.
Appearing as an amorphous sphere of liquid, the Spherimorph is resistant to physical attacks and absorbs magic of all elements except one, determined randomly. Hitting the Spherimorph with its elemental weakness will cause it to change to absorb that element and become weak to another (because this element is randomly determined from all four elements, it can sometimes end up weak to the same element it was before). Its current elemental weakness can be discerned because it always counterattacks against physical attacks with the opposite element's spell.
On its turn, Spherimorph will transform into a pillar and stomp one party member, dealing high damage, enough to KO low-HP characters. Occasionally, it may flatten out and use Press, which reduces the party's HP by half.
The best strategy is to have one character attack physically, wait for the enemy to counter with a spell, then have Lulu attack with the opposing spell. Aeons of the right element, or ones that have learned appropriate spells, can be summoned for one turn and then dismissed if necessary.
Yuna can cast her Nul-Spells to protect the party from Spherimorph's magic attacks, and Rikku's mixes can also be used for this purpose. Valefor is good for the battle because of its Energy Ray and ability to cast black magic. Spherimorph is vulnerable to Power Break and Magic Break, which will render its attacks non-threatening.
Spherimorph, is a compound word, made of "sphere" and "morph". Sphere is a word that has its roots in the Greek language, as "σφαίρα", pronounced "sphaira", and morph, which is also a word originally from Greek, as "μορφή", pronounced "morphee", and means shape. Therefore, Spherimorph means "that, which has the shape of a sphere".
Its Japanese name is "Sphere Manager", a reference to being born from the same water used to create spheres.
