Solo Mage Tifa vs Full Might Odin [ 

Slightly Modified Build from my previous Video
Replaced Opening ATB Boost with Enhanced Elements
Replaced Auto Weapon Ability with Elemental + Wind in the weapon
Note: These solo summons are Harder on Dynamic than Normal/Hard so this is the toughest solo odin possible.
Thanks to her insane ATB Generation while using level 2 Unfettered Fury, Tifa is uniquely adept at using Tier 3 Magic Spells. By using ATK--MATK Switch we can leverage her naturally high Strength Stat and apply it toward her spells.
