Cloud of Darkness is the final boss of Final Fantasy III and is encountered twice. It is first encountered in an unwinnable storyline battle after Xande has been defeated. At the very end of the game, after the party has traversed the World of Darkness, the Cloud of Darkness is fought again, but if the player has not freed all the Warriors of the Dark in the final dungeon before doing so, the final boss will have an unparalleled high defense stat and the heroes will find themselves fighting a losing battle.
NES battle Edit
The Cloud of Darkness will usually only use a single attack, Flare Wave, which does 1,200–1,500 HP of damage to the entire party. On some rare occasions it uses a physical attack that ignores the character's Defense and will likely result in an instant kill.
NES strategy Edit
Realistically one needs at least two high-level White Magic users to prevent the party being overwhelmed and destroyed by the damage from the Flare Wave. Once the player is able to bring the damage sustained by the party under control, the battle becomes mostly an endurance test. Two Sages and two Ninjas is considered the optimal party make-up. Alternatively, three Sages and one Ninja will further increase the party's chance of survival if all three Sages focus on healing, though it makes for a long, tedious battle.
The player should use all of their shurikens (and make sure they reequip every round). The Sages can cast Haste on the Ninjas the first round (if not using shurikens). Afterward, the party will probably have to cast Cure4 every round. If it seems like there is a round of respite, the player can call Bahamut. If the party runs out of magic, they can use Elixirs.
Remake battle Edit
The Right Tentacle is immune to physical attacks, but not magic. The Left Tentacle is immune to magic and must be taken down with physical attacks. The Right Tentacle is weak to all elements. The Left Tentacle uses a Lightning attack.
Each tentacle seems to have 66,666 health each(untested), so putting effort to kill each one will be an effort, but also very worth it.
The Cloud of Darkness can use Bad Breath to hamper the party unless the members are equipped with Ribbons or Aegis Shields. Otherwise, only its physical attacks pose an actual threat (although they do not ignore defense in this version) until it starts to use Particle Beam (the same as Flare Wave from the NES version).
Remake strategy Edit
Although difficult, the Cloud of Darkness can be defeated by solely attacking its main body. However, destroying the Tentacle on the player's left first makes the rest of the battle easier because of its powerful Lightning attack. Casting Firaga or Holy on the Right Tentacle will do large amounts of damage.
A Devout is highly recommended as they can use high level White Magic, including Curaja and Arise, more often and more powerfully than the Sage and can support the party with Protect or cast Holy on the Cloud of Darkness. Protect can only be cast on one person per turn so that strategy is optional. Warriors can use the Advance ability to deal heavy damage to either the Right Tentacle or the Cloud of Darkness. Ninjas are useful for their Throw ability and they can also inflict massive physical damage to the Cloud of Darkness while dual-wielding the Masamune and Muramasa. It is preferred for Dark Knights and Dragoons to attack normally and only use boosts provided by Devouts and Bards, both of which are recommended to be in the back row. Bards can also use Sing with a Loki Harp for a more effective attack bonus. Black Belts can use Boost to save a Devout's turn.
Behind the scenesEdit
In the first battle with it, the Cloud of Darkness is immune to nearly all attacks. In the remake version, a Dark Knight's Souleater attack, a Bard's Requiem Sing, and a Ninja's weapon Throw will deal regular damage to it. The battle will still likely end before enough attacks can be used to kill it though as the Cloud of Darkness will still deal full damage to the entire party.
