Mortiphasm

Mortiphasms are bosses from Final Fantasy X. They are fought with Seymour Omnis, and are four disks around him.

Strategy
As a Mortiphasm disk rotates, a colored section will face the side closest to Seymour; these will determine which four level-three spells Seymour Omnis will cast at the party each turn. If each color is the same, the spells will have increased power. Seymour Omnis' magical weakness is determined by whichever side is furthest away from him when he is attacking. After each attack, the disks will rotate so a new spell is used. As the disks are all facing the same way at the beginning of the battle, one of the first actions should be to forcibly rotate one by attacking it, this will prevent a barrage of very powerful spells being cast one after the other. Physically attacking a Mortiphasm will cause it to rotate to the left, and using magic will cause it to rotate to the right. However, the Mortiphasms, unlike Seymour Omnis, are out of reach, so only Wakka can attack them physically
