Call Psynergy series

The Call Psynergy series is a series of Mercury, Venus, and Jupiter Psynergies introduced in Golden Sun: The Lost Age. Call Dullahan, the strongest Psynergy in the series, is noteworthy for having the highest damage multiplier of any Psynergy in the Golden Sun series.

Basic Characteristics
Call Zombie, Call Demon, and Call Dullahan are single-target, offensive Psynergies. The offensive power of Call Zombie is determined by comparing the user's Mercury Power and the target's Mercury Resistance, and multiplying the resultant ratio by the base power of Call Zombie. Call Demon and Call Dullahan are Attack-dependent, meaning characters with higher Attack ratings will deal more damage with these attacks. In addition, the caster's Venus or Jupiter Power and the target's Defense and Venus or Jupiter Resistance all factor into the damage dealt.

Visually, each stage of the series features a monster being summoned to attack the target in place of the caster. Call Zombie shows a Zombie performing its standard Attack. Call Demon shows a Red Demon using its signature move Vital Moon. Call Dullahan features a dullahan (a different one than the infamous boss) attacking the target with its signature move,.

Availability
The Call series is unique to the Dark Mage class series, an item dependent class accessed by equipping the Tomegathericon. The Tomegathericon is only found in Golden Sun: The Lost Age and thus the Dark Mage class series is limited to the game's eight playable Adepts.

At first, Call Zombie will be the only Psynergy available, and is learned at Level 1. Call Demon is learned at level 26, but only when the Adept is in the Necrolyte stage, which requires 6 Djinn divided equally between the three elements opposite to the user's own. Call Dullahan is learned at Level 47, but only when in the Necromage stage,which requires 9 Djinn divided equally between the three elements opposite to the user's own. Contrary to popular belief, the player need not defeat Dullahan in order to use the Psynergy. In fact, Call Dullahan can be used against the real Dullahan.

Analysis
General: The Call series is one of the most important series in the Dark Mage's repertoire. Despite the Dark Mage's below-average Attack stat, Call Demon and Call Dullahan have high enough damage multipliers for any Adept to do high amounts of damage. Call Zombie is a decently strong option for early parts of the game, but is quickly outclassed. When learned, Call Demon is useful during mid-game both for its high damage multiplier, and for its occasional chance to reduce a target's HP to a single point. Call Dullahan is likely the single-most powerful Psynergy in the series, and will do large amounts of damage no matter which Adept uses it.

By Game
Golden Sun: The Lost Age: Call Zombie will see little use due to the fact that the class is not available until mid-game. Call Demon will do decent damage against most bosses in the Eastern Sea through Jupiter Lighthouse, barring the Serpent, which is highly resistant to Venus. Call Dullahan is useful against nearly every endgame boss, due to its high damage multiplier. Combining it with a 99%-Unleash Sol Blade user will decimate most opponents. In particular, the final boss and Dullahan both have weaknesses to Call Dullahan's Jupiter alignment.
