Ice Psynergy series

Ice (アイス, Ice), Ice Horn (アイスホーン, Ice Horn), and Ice Missile (アイスミサイル, Ice Missile) are a series of offensive Mercury Psynergy featured throughout the.

Basic Characteristics
Ice, Ice Horn, and Ice Missile are offensive, ranged Psynergies. The total damage inflicted is determined by comparing the caster's Mercury Power to the target's Mercury Resistance and using this number to modify the base power of the particular Psynergy in use.

Visually, the Ice series features a mass of ice spikes forming in the sky and falling diagonally to strike the targets. The number and size of the ice spikes increase with each stage.

Availability
The Ice series is unique to the Water Seer class series, available to Mia and Rief. The Water Seer class is a mono-elemental Mercury-based class that is available to Mia and Rief when they have no or only Mercury Djinn Set. Ice is available at Level 4, Ice Horn at Level 17, and Ice Missile at Level 42.

Analysis
General: The Ice series is the most powerful series available to the Water Seer class. In this way, it is often compared to the Mariner class series's Cool Psynergy series. The main difference is that Ice Missile is more cost-effective, being less expensive and yet similarly powered to Cool, and has a more limited range. Due to the Water Seer's limited Psynergy lineup, Ice Missile ends up being the most commonly used offensive Psynergy, due to its power in comparison to the Frost/Douse series.

By Game
 and : Mia will know Ice when she joins Isaac's party, and as the only Water Seer in either game, remains the source of the series. Ice Horn can be an excellent offensive option during the first game, but will be replaced by Glacier by the end, due to the large level difference between Ice Horn and Ice Missile. In The Lost Age, Ice Missile will be Mia's main attack by the end of the game, and can do a great deal of damage to the Mercury-weak monsters at Magma Rock and Mars Lighthouse.

Golden Sun: Dark Dawn: Rief will know Ice when he joins the party, and Ice Horn will be extremely useful when learned. As the game progresses, the series is temporarily discarded in favor of Deluge, Drench, and possibly the Cold Snap Psynergy series. However, Ice Missile will still be the strongest option, and can be useful against end-game opponents.

Psynergy cast by enemies
Members of the Ice series are somewhat common amongst enemy Psynergy lineups. Many fightable Mercury Djinn can cast at least one stage of the series. In addition, many randomly encountered monsters can cast a member of the Ice series. The Spirit can cast Ice, while the Horned Ghost and a Mimic can cast Ice Horn. Meanwhile, a Cerebus and another Mimic can cast Ice Missile. Amongst bosses, Ice Missile is among the arsenal of Dark Dawn's Ice Queen, and it is her strongest offensive Psynergy.
