Bane

Bane is a Venus Djinni found in Golden Sun and Golden Sun: The Lost Age.

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

Basic description

 * "Attack with nature's venom."

When Set, Bane increases its Adept's base HP by 12 and base Attack by 4.

When Bane is unleashed in battle, the user deals a Venus-based attack equal in power to the user's normal physical attack with an additional 60 damage points added to the result. Then, there is a chance that the target will be inflicted with the Venom status condition, causing them to lose a lot of HP at the end of each turn.

In Golden Sun and The  Lost Age, Bane's unleash animation visually resembles a normal physical attack that lets loose a glowing white-red mist cloud on impact.

Damage calculation
Elemental physical attacks such as Bane 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

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


 * ''final damage = (base damage + 60) * (1 + (Attacker's Venus Power - Target's Venus Resistance) / 400)

To word this in prose, Bane takes the base damage of the user's normal  physical attack, adds 60 to it, and then this result is modified  by how  much higher or lower the user's Venus Power is than the target's  Venus  Resistance. The difference between the user's Venus Power and the   target's Venus 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 Bane's damage is multiplied by.

For example, if an Adept with an Attack rating of 300 and a Venus Power of 150 unleashes Bane on a monster with a defense of 120 and a Venus Resistance of 100:


 * damage = ((Attack - Defense) / 2 + 60) * (1 + (Power - Resistance) / 400)
 * damage = ((300 - 120) / 2 + 60) * (1 + (150 - 100) / 400)
 * damage   = ( / 2 + 60) * (1 +  / 400
 * damage   = ( + 60) * (1 + )
 * damage =  *
 * damage = 168

Therefore,  if Bane were to be unleashed under these circumstances it would deal    168 points of damage.

Locations
Golden Sun: Bane is located in the sixth floor of the optional Crossbone Isle. The entire room is a puzzle maze that must be fully solved in order to both exit it and get the Djinni, with  the idea being to hound it to the elevated portion at the lower right of  the room and trap it with Halt like on Kite at Vale Cave. Refer here for the full walkthrough on Floor 6 of Crossbone Isle.

Golden  Sun: The Lost Age:  Players must transfer data from Golden Sun to The Lost Age in order for Bane to be acquired at all, because if they don't, Bane will not be among the Djinn Isaac's party has with them when they join forces with Felix's party late in the game, and the "make-up" Venus Djinni at the end of Treasure Isle will be the other missing Venus Djinni from the first game, Ground.

Analysis
General: Bane is a pretty good offense to take because of the chance to inflict the directly powerful Venom status condition. With Venom out of the equation, though, this is not an especially strong Djinni from a late-game perspective because it is found near the end of each game it appears in, and the 60 set bonus damage will be outclassed by Djinn like Flint that deal damage enhanced by a multiplier.

By game
Golden Sun: Bane is very valuable because of the powerful and practical Deadly  Poison effect it can trigger, making it one of only two possible options  the party has to apply Deadly Poison (the other being the Unleash  effect of the Wicked Mace). What blunts its usefulness is that the endgame enemies it would have the greatest effect upon - Deadbeard,  Saturos and Menardi, and the Fusion Dragon - are nearly  immune to status effects being applied onto them, and random monsters  typically die in very few rounds of battle before the venom has a chance  to kick in and be useful. As for pure damage, Flint outperforms Bane in that area in an endgame party. However, that it has the highest added base damage in the first game makes it respectable even if its  secondary effect does not kick in, perhaps as a substitute for Flint. Possibly the best chance for this Djinni to shine is when used against the mini-bosses of Crossbone Isle in the remaining floors, such as  against the Cerebuses (the venom will do an astounding 440 or so  damage at the end of each turn to a Cerebus). It also works effectively against the infinitely respawning Tempest Lizard of Suhalla  Desert, as it is one of the few endgame bosses not completely immune  to venom. This makes for a quick fight and high EXP.

Golden   Sun: The Lost Age: When Isaac's party joins Felix's party along with their returning Djinn (granted that Password data transfer is in effect), Bane is  essentially a slightly stronger Venus-element variation on the Jupiter  Djinni Wheeze. Whenever the Venom effect kicks in, it deals heavy damage based on how much HP the enemy has, but the near-immunity of any boss-like enemy prevents that effect from happening from either of these  Djinn.

Name Origin
Bane was a term used in the middle ages for poisonous plants, possibly why this Djinni is capable of poisoning its target. In addition, plants are associated with the Earth element, which makes sense for a Venus Djinni.
