Succubus (Psynergy)

The Succubus Psynergy is a stand-alone Support Psynergy available only to the Beast Lord class. Its name comes from the Succubus, a boss of Crossbone Isle in the first Golden Sun, although the monster it summons is actually a Siren, the weakest member of Succubus' monster line.

Succubus is a basic Mercury Psynergy that functions as a slightly stronger variant to the more commonly used Ply Well; instead of restoring 200 HP to one character for 8 PP, it restores 250 for 9. This makes it quite a bit more useful when the extremely low PP of the Beast Lord class is taken into consideration, but this is offset by being learned at a much later level (Ply Well is learned at Level 16; Succubus is learned at Level 24). Furthermore, as the Succubus Psynergy is only available to the Beast Lord class, it requires the player to collect almost all the Djinn in The Lost Age (as the Beast Lord class requires 9 Djinn to be set onto a single Adept), it is only available toward the very end of the game, meaning that the player would probably already have acquired the much more potent Pure Ply (available at level 34) by the time this Psynergy becomes available.

Trivia

 * Sirens are called Succubi in the Japanese version of Golden Sun, which explains why the Succubus Psynergy counter-intuitively summons Sirens.
