Seymour Omnis Boss Battle Guide

Seymour Omnis defeated


Seymour's moves will vary depending on the position of the discs. Each disc has 4 colors in it representing elements. The more elements of the same color pointed at Seymour, the more damage his spells will deal. Seymour will then cast 4 spells each representing a color on the disc to the party, 1 for each character and the last one at a random target.


Level 1 Black Magics Fire, Thunder, Blizzard, Water
Level 2 Black Magics Fira, Thundara, Blizzara, Watera
Level 3 Black Magics Firaga, Thundaga, Blizzaga, Waterga
Dispel Removes all positive status effects.
Ultima Deals massive non-elemental damage to all party members.
Cannot be reflected.


It is advisable to get equipment that absorbs a certain element to be able to focus on attacking Seymour. If not applicable, use Yuna's Nul spell for the corresponding element Seymour has. Use Auron's armor break to reduce Seymour's defense and keep attacking him.

When Seymour uses Dispel on the team and glows red, this means Seymour signals the use of Ultima, a non elemental spell that deals around 4000 damage to the whole team. Bring Yuna infront and summon an Aeon then make it use Shield to reduce the damage of Ultima.
