If you will not have eternal life, I will give you eternal suffering!The Emperor
Starfall XVI targets the whole party, and hits for moderate damage. The Emperor uses Flare XVI frequently, alternating between this and his Starfall XVI attack. The Emperor sometimes casts Holy XVI or Blaze XVI on the whole party. He repeatedly casts Dispel XVI to remove the party's buffs. The Emperor's regular attacks hit for high damage and also heal him.
If the player gave the Blood Sword to Ricard in the main game, the fight against Emperor will be a simple affair as sixteen hits at most will eliminate him. Dual-wielding it with Ricard's Wyvern Lance or Scott's Wild Rose ensures maximum accuracy.
Otherwise, the party should be bolstered with buffs, such as Haste, Blink and Berserk. If Scott's Wild Rose has been obtained, it can be used to cast Berserk XVI on the entire party. As the Emperor does not use many status effects, Shell and Barrier are not necessary.
The Emperor's offense comes primarily from his magical attacks, of which only Blaze XVI can be mitigated. Thus, it is important to have high HP and to have Minwu and/or Scott heal as necessary. Using the Ancient Sword to inflict Curse makes the fight much easier, as the party will inflict greater damage to the Emperor and receive reduced damage from his attacks.
Light Emperor is a DLC costume for the Emperor titled "Emperor of Arubboth", or simply "Arubboth". Despite being a heavenly being, the EX Mode for the Emperor while wearing this costume is still called "Power of Hellfire."
Light Emperor appears as a boss.
