Fever


 * This Djinni appears as an enemy that can be battled.

Fever (コロナ Corona) is a Mars Djinni found throughout the Golden Sun series.

Fever is the second Mars Djinni in both the original Golden Sun and Golden Sun: Dark Dawn. Fever is also acquired in Golden Sun: The Lost Age, and although it is not the party's second Mars Djinni, Fever is still ordered as the second Mars Djinni when equipped to characters. Because it is not available until after most other Mars Djinn can be found, however, the separate Djinn list viewable with the Select button from the status screen lists Fever and all other Mars Djinn from Golden Sun after all of the Djinn introduced in The Lost Age. According to this order, Fever is the thirteenth Mars Djinni in The Lost Age rather than the second, but this order has no influence elsewhere in the game.

Basic description
When Set, Fever increases its Adept's base HP by 8, base Attack by 3, and base Agility by 2.

When Fever is unleashed in battle, the user deals a Mars-based attack equal in power to the user's normal physical attack with an additional 30 damage points added to the result. Then there is a chance the target will be afflicted with the Delusion status condition.

In Golden Sun and The Lost Age, Fever's unleash animation visually resembles the user performing a fairy typical strong Mars attack, and then an orange cloud is let loose upon impact. In Dark Dawn, the user still leaps through the air, but a 3D model of Fever hovers behind them and, when the user strikes the target, their weapon and the area of ground underneath and behind the target is cloaked in fire.

Damage calculation
Elemental physical attacks such as Fever use the damage dealt by the attacker's standard physical attack as the base damage to be later modified. The total amount of damage dealt by a normal physical attack is half the difference between the attacker's Attack statistic and the target's Defense statistic, as this equation shows:


 * ''base damage = (Attacker's Attack - Target's Defense) / 2

Fever's attack then takes this base damage value and uses it in the following equation:


 * ''final damage = (base damage + 30) * (1 + (Attacker's Mars Power - Target's Mars Resistance) / 400)

To word this in prose, Fever takes the base damage of the user's normal physical attack, adds 30 to it, and then this result is modified by how much higher or lower the user's Mars Power is than the target's Mars Resistance. The difference between the user's Mars Power and the target's Mars Resistance is divided by 400, then 1 is added to this, resulting in what can be called the "elemental damage multiplier". This number is what Fever's damage is multiplied by.

For example, if an Adept with an Attack rating of 100 and a Mars Power of 120 unleashes Fever on a monster with a defense of 20 and a Mars Resistance of 70:


 * damage = ((Attack - Defense) / 2 + 30) * (1 + (Power - Resistance) / 400)
 * damage = ((100 - 20) / 2 + 30) * (1 + (120 - 70) / 400)
 * damage = ( / 2 + 30) * (1 + / 400)
 * damage = ( + 30) * (1 + )
 * damage = *
 * damage = 78

Therefore, if Fever were to be unleashed under these circumstances it would deal 78 points of damage.

Locations
Golden Sun: Fever reposes in Imil Falls Cave, the tiny cavern at the town of Imil, reachable by sliding around through the frozen river and into the hole of the frozen waterfall. To reach there, first you have to stand in front of the snowman at the north end of the town and cast Move to shift it left and drop it onto the frozen ice river below. Then entering the river via the opening just to the right of the sanctum in the southwest part of town, slide right, up, left, up, left, up, right, up, left, up, right, and up to enter the opening. You automatically slide into Fever, and press A to immediately add it to your collection.

Golden Sun: The Lost Age: Players can transfer data from Golden Sun to The Lost Age, but even if they don't, Fever will be among the Djinn Isaac's party has with them when they join forces with Felix's party late in the game.

Golden Sun: Dark Dawn: Fever is the first Djinni that can be encountered by random battle while exploring a specific part of the game's overworld. In this case, it is the stretch of land that the player travels south through while traveling from Carver's Camp to desert lands surrounding Konpa Ruins. It seems programmed so that it is impossible not to get into a random battle with Fever. When the Djinni is defeated in battle, it is added to your inventory. As this area of the overworld map is one of the locations within the first region of the game, which gets locked off the moment you enter the Ei-Jei region, Fever can be permanently missed if you do not take the ample opportunity to collect it. See here for enemy statistics.

Analysis
General: As the "basic" offensive Mars Djinni, Fever is best used as soon as it can be acquired in each game it appears in, because its 30 set damage bonus is quite substantial if the equipped Adept's physical attack only does roughly 30 damage on its own. However, at the end of each game, it is entirely obsolete in comparison to other Mars Djinn because 30 set bonus damage is all that can be gotten out of it.

By game
Golden Sun: Fever is the weakest of the three available offensive Mars Djinn from an endgame perspective; like Torch, it only adds 30 damage points, but unlike Torch, the added status effect of Fever, the Delusion status condition, is considered to be rarely helpful to have inflicted on enemies because Delusion's associated accuracy drop does not apply to anything that is not a normal physical attack. Fever is quite useful to make use of early on in the game when it is first acquired, though, for at that point 30 additional damage is quite substantial. Fever is a Djinni whose effect becomes less valuable over time when your focus is using only stronger Djinn to conduct and win battles with, such as the stronger Scorch. Another strong Djinni, Smog, doubles the damage added and retains the delusion effect.

Golden Sun: The Lost Age: When Isaac's party joins Felix's party along with their returning Djinn, Fever becomes all the more obsolete as a method of attack you would use if you want to make battles won easily, similarly to the Mercury Djinni Fog that is found earlier in that game and has the same extra damage, particularly because another Mars Djinni exists whose battle effect is an interesting upgrade on Fever; Shine, found in Contigo as soon as the party joins, which adds 60 damage and has a chance to inflict Delusion on all enemies (making it an upgrade to even Smog), including the ones not specifically targeted by the user of Shine. Whether even that Djinni is used in battle is another story, but it certainly obsoletes Fever on its own.

Golden Sun: Dark Dawn: Fever is the weakest offensive Mars Djinni because it has the lowest added damage bonus (30) and the chance to inflict a status effect that isn't the most useful. For the period of time while this remains your only attacking Mars Djinni, though, this is still quite useful because 30 additional damage points is quite substantial. However, if you have this and Forge, you are probably better off having the two of them Set onto one Adept so that they will be in the next stage up in their class series, giving them much more in all of their statistics. In the boss fight against the Stealthy Scouts, you may decide to have the Adept with the two Set Mars Djinn use Forge to boost the party's attack power first, then use Fever to deal an enhanced attack, and finally summon Kirin with the two On Standby Mars Djinn. It will be outclassed by the far superior Lava once that is obtained in Kaocho after the segment of the game in Ayuthay.

Name Origin
A fever is a symptom where the body's internal temperature rises above normal. A corona is the high-altitude gaseous envelope of the sun that we can see during a solar eclipse as the golden ring around the blocked-out sun. Note that the English translation of the games switched the names of Fever and Corona.

Trivia

 * Prior to Dark Dawn, all Djinn of the same element shared the same design. Djinn were later given individualized appearances, but Fever retains the original Mars Djinni design as its own appearance.
