Spherimorph 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 spring , the water used to create spheres . With no warning , the Spherimorph attacks the party . Following the battle , Tidus will receive the first Jecht Sphere and Auron will learn his second Overdrive , Shooting Star . A tougher version of this fiend , Greater Sphere , can be unlocked in the Monster Arena . Battle . Appearing as an amorphous sphere of liquid , the Spherimorph is resistant to physical attacks and absorbs magic of all elements except one that is determined randomly . Hitting the Spherimorph with its elemental weakness will cause it change its elemental weakness with Elemental Shift . Because the element is randomly determined from the four main elements ( it is never Holy ) , it can end up weak to the same element it was before . Its current elemental weakness can be discerned from its counterattacks that use a spell of the opposite element . On its turn , Spherimorph will transform into a pillar and stomp a party member , dealing moderate damage . Once its HP has been halved it may flatten out and use Press , which halves the party ' s HP and is unaffected by Protect . Spherimorph responds with different counterattacks in different situations . When hit for any damage of the element Spherimorph is currently weak against , or when hit for special damage of any element that Spherimorph is currently under the corresponding Nul status for , Spherimorph responds with Elemental Shift . When hit with physical or non - elemental special damage , or elemental magical damage from an aeon , Spherimorph responds with the spell of the element opposite to its weakness , targeting a single character . When hit with magical damage from party members , Scan , or non - weak and non - Nulled elemental special damage , Spherimorph responds with the same spell but targeting the whole party . Spherimorph ' s whole - party elemental spells are about 40 % stronger than its single - target spells . When hit with a reflected spell Spherimorph does not follow its usual counter pattern , but repeats whichever counterattack was used last . If it has not yet used any counterattacks , it will not counter reflected spells . If Spherimorph is hit by a character ' s counterattack , it will not counter - counterattack , but on future reflected spells will act as if it did . Spherimorph is vulnerable to Power Break and Magic Break , which will render its attacks non - threatening . Strategy . The best strategy is to have one party member attack physically , wait for the enemy to counter with a spell , then have Lulu attack with the opposing spell ( such as if Spherimorph counters with Blizzard , Lulu should follow with Firaga ) . Aeons of the right element , or ones that have learned appropriate spells , can be summoned for one turn and then dismiss ed if necessary . As always , beating it with an Overkill nets double AP , and the easiest way to do this is with an aeon Overdrive . Yuna can cast her Nul - Spell s 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 its Energy Ray does not run the risk of healing the creature , and she can cast black magic . If the party has a Poison Fang , it can be used on Spherimorph . It will initially deal about 2000 damage and the Poison will do exactly 600 damage each time Spherimorph takes a turn . Poison Fangs can be stolen from the wasps nearby as a rare steal . Poison will not trigger Spherimorph to counter . Although Spherimorph has a high resistance to Poison , the Poison Fang will inflict poison 100 % of the time . This strategy is extremely helpful if playing the game without the Sphere Grid . Etymology . Spherimorph is a compound word of " sphere " and " morph . " Sphere has its roots in the Greek language , as " σφαίρα , " pronounced " sphaira , " and morph also originates 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 , " referring to being born from the same water used to create spheres .
