Mist (Djinni)

Location
Mist is visibly located in the town of Xian. To get to it, note a woman that patrols between the river and the right of two brown doors embedded into a brown wall below the town's dojo. As soon as you talk to her, a Frost-able puddle suddenly appears at her position, and she tells you off for making her drop her bucket of water. Talk to her when there is one tile between herself and the door she stops in front of, then use Frost on the resultant puddle to form a pillar you can hop across to reach the Djinni to the right.

Description
When Set, it increases base HP by 11 and base Attack by 4.

When Sleet's battle effect is used, the user deals an attack that lets loose a white vaporous cloud on impact, dealing a Mercury-based attack equal in power to the user's normal physical attack increased by 30%. There is then a chance that the target may be afflicted with Sleep.

Ability analysis
In Golden Sun, Mist has the highest damage potential of the three available offensive Mercury Djinn from an endgame perspective; since its damage enhancement takes the form of a multiplier, it will do more damage the higher leveled the user is. In addition, Sleep is a good status ailment to place on an enemy. It is perhaps best used on a party that is not using a class setup comprised of default mono-elemental classes, though, for the Mercury Adept Mia is generally designated as a healing and support character, and her physical attack does not get as high as Isaac, so Mist may be "wasted" on her despite it being her potentially strongest single-target offense.

In The Lost Age, when Isaac's party joins Felix's party along with their returning Djinn, Sleet is used less because its damage multiplier is outperformed by two other Mercury Djinn, Sour and Gel, which both have a 50% damage increase, and when used by the more offense-oriented Mercury Adept, Piers, one would typically want the greater overall damage output of those. One must take the secondary effects of these three Djinn into account, though, and the secondary effects of Sour and Gel are to drop all of an enemy's resistances by 40 each and to drop the enemy's Attack rating by 25%, respectively. Depending on your taste, Sleep being a more crippling effect to the target may make Mist equal to, if not better than, Sour and Gel despite dealing less immediate damage. It's side effect proves to be somewhat reliable against the bosses encountered after Xian.

Name Origin
Mist is water vapor in the air that sometimes obscures vision.
