Sleet

Location
Sleet is located in a hidden room behind one of the many waterfall-walls in a hallway in Mercury Lighthouse, the hallway immediately following a room where a pipe spout pushes open a massive section of wall to the left to reveal a door; you must press up against the wall so that you enter the room as though you walked through a house's door. (The best way to find it, as well as various other secrets of Mercury Lighthouse, is to press up against each waterfall-wall you pass by in the entire dungeon.) It must be battled to be acquired.

As an opponent
Statistically, Sleet has 290 HP, 20 PP, 107 Attack, 24 Defense, 58 Agility, and 9 Luck. Like all other Mercury Djinn that are fought, in terms of resistance, it has a Mercury Resistance rating of 193, Venus and Jupiter Resistance ratings of 100 each, and a Mars Resistance rating of 25, and in regards to its abilities it uses its available Mercury-based attacks with a Mercury power rating of 125.

Sleet can use the following battle commands:
 * Attack: Used 81 out of 256 times, this is this monster's standard physical attack, but for this monster it is counted as a Mercury-based attack rather than a non-elemental attack.
 * Prism: Used 47 out of 256 times, this is a Psynergy spell that causes a large piece of ice to drop from the sky and slam and shatter into the party, dealing a Mercury-based attack with a power rating of 40 and a range of 3. This ability consumes 7 of its user's PP.
 * Tundra: Used 41 out of 256 times, this is a Psynergy spell that causes a moderate amount of ice shards to drop onto the party, dealing a Mercury-based attack with a power rating of 45 and a range of 3. This ability consumes 8 of its user's PP.
 * Drench: Used 35 out of 256 times, this is a Psynergy spell that causes a moderately long array of watery spheres to drop out of the sky and onto the targeted Adepts, dealing a Mercury-based attack with a power rating of 60 and a range of 3. This ability consumes 10 of its user's PP.
 * Froth Sphere: Used 29 out of 256 times, this is a Psynergy spell that projects a moderately large array of watery spheres that arc into the party, dealing a Mercury-based attack with a power rating of 65 and a range of 5. This ability consumes 12 of its user's PP.
 * Flee: Used 23 out of 256 times, this enemy has the ability to attempt to Flee the battle, thereby ending the battle if successful without rewarding you with the associated EXP, Coins, and the Djinni itself, and the Mercury Djinni disappears from its field spot. If this happens to you, however, you are practically at the entrance/exit you went through to get to Sleet in the first place, so going in and out of it will make Sleet reappear in its usual spot instantly, and it can easily be battled again.

When defeated, Sleet yields 130 EXP and 151 Coins, and the Sleet Djinni is added to your party's Djinn collection. If you fell it with an offensive Mars Djinni like Fever, its rewards increase to 169 EXP and 196 Coins.

Sleet has a wide variety of offensive Mercury Psynergy to work with, with Froth Sphere being its strongest offense - but its PP meter limits its usage of that to once per battle, and it is not likely to use that at all. By this point it is possible to have two each of Venus, Mars, and Jupiter Djinn, so summoning Ramses, Kirin, and Atalanta and having Mia attack should defeat it in one turn. All future Djinn can be taken out quickly with heavy summoning in this manner.

Description
When Set, it increases base HP by 12, base Attack by 3, and base Luck by 1.

When Sleet's battle effect is used, an image of a Mercury Djinni projects a stream of icy shards at the target, dealing a Mercury-based attack equal in power to the user's normal physical attack with an additional 30 damage points added to the result. There is then a chance that the target's Attack rating will be temporarily reduced by 25%.

Ability analysis
In Golden Sun, Sleet is the weakest of the three available offensive Mercury Djinn from an endgame perspective; it only adds 30 damage points, compared to the 40 damage points of Hail and the 1.3x damage multiplier of Mist. But for when it is found somewhat early on in Mercury Lighthouse, 30 additional damage points is quite substantial, and it does more damage to the upcoming boss Saturos than most other offenses the party has available outside of summoning, even if it is used by Mia, who is supposed to be physically weak and more focused on party healing. The attack-lowering effect, since it only applies based on a chance and does not work on bosses, and does not lower the damage output of Psynergy spells, may hardly benefit the player's party in the long run at all. Sleet is a Djinni whose effect becomes less valuable over time when your focus is using only stronger Djinn to conduct and win battles with.

In The Lost Age, when Isaac's party joins Felix's party along with their returning Djinn, Sleet becomes all the more obsolete as a method of attack you would use if you want to make battles won easily, particularly because another Mercury Djinni exists, Gel from Kalt Island, that has the same attack-reduction effect but a far stronger 1.5x damage multiplier. Sleet and Gel are the only two Djinn in the series to lower enemy attack.

Name Origin
Sleet is wet snow and ice that falls from the sky. A sorbet is a frozen desert similar to ice cream, but without dairy products and usually with fruit.
