Deumion (boss)

Deumion is a superboss from the 20th Anniversary and iOS versions of Final Fantasy II. He is located in the Arcane Labyrinth, guarding the Destroy Tome, and will test the party with a fight against Phrekyos before the player can face him.
After defeating Phrekyos, the player can ask him a keyword. To fight Deumion, the player must choose "Destruction". He is the only enemy in the game that lacks a bestiary entry.

== Battle ==
Deumion's battle AI is as follows:
: Flare XVI (20%), Blaze XVI (20%), Blizzard XVI (20%), Starfall XVI (15%), Holy XVI (10%), Slow XVI (10%), Dispel XVI (5%)
Deumion will not use normal physical attacks unless he is out of MP.
Flare XVI and Slow XVI are his only single-target spells, while every other spell attacks the party. Deumion's ultimate attack, Starfall, can be devastating if the party has low magic defence as it can easily do a couple thousand HP in damage. 
When the party defeats him, they will be granted access to the Destroy Tome, the most powerful spell, even surpassing the fabled Ultima.
=== Strategy ===
As Deumion attacks only with magic while he has MP, having high magic defense will greatly aid with survival. Low magic defense characters can have Shell cast upon them to help mitigate damage from most of Deumion's attacks. Fire and Ice resistance can help with reducing damage from his Blaze XVI and Blizzard XVI attacks, and Body element resistance can avoid his Slow XVI. If a character is not geared with equipment granting resistance to the aforementioned elements, they can be added via the Barrier spell. However, if Dispel XVI connects on anyone, they lose their elemental resistances, even from equipment. Barrier should be cast on anyone who suffered a Dispel XVI. Group-casts of Cure should be used to heal his heavy party-wide damage when necessary.
Alternatively, the party can drain out Deumion's MP and force him to use his weaker single-target physical attacks. As he absorbs the Mind element, Sap cannot be used, but the non-elemental Osmose is still effective. While he has a sizeable MP pool, Osmose at Lv8–10 can usually drain all his MP in one or two casts. Blink and Protect are useful options in negating his physical damage output.
To attack, physical attacks generally work better as Deumion resists or absorbs every element and has high magic defense. While his physical defense is also high, his evasion is low and exploitable by rapid hits. Berserk, Haste, and Aura Lv5 or higher should be used to buff the party's physical fighters. Haste can also be used to counter the effects of Slow XVI, should anyone be hit by it.
If the party insists on magical attacks, the non-elemental spells Holy and Flare are the best options. If properly leveled, Ultima can be a stronger option due to it ignoring magic defense.
