Planet Diver and Planetary

Planet Diver and Planetary are two single-target Psynergies of the Mars element and are among the games' most powerful single-target Psynergies. They are usable by Venus Adepts Isaac and Felix and the Mars Adepts Garet and Jenna while they are in the Brute class series.

Planet Diver
Planet Diver is described as "leap skyward and lunge onto a foe". The user leaps in to the sky and using gravity comes down on the target and attacks them. It is available to the Brute class series. Due to how powerful it is, it is extremely useful against any enemy including Saturos and later Menardi. It costs 7 PP to use and strikes the target with Mars power equal to the user's own attack power with 36 base Attack added.

Planetary
In Golden Sun: The Lost Age, after reaching the Berserker class, Planet Diver is replaced by the more powerful (and more expensive) Planetary. Planetary is described as "strike a foe with fire from the heaven". It is almost the same as Planet Diver but the only difference is that instead of looking like a meteorite coming down, the user takes on the form of a giant dragon head coming down. Despite being expensive, the power alone makes it worth using against many enemies. Planetary costs 19 PP to use and strikes the target with Mars power equal to the user's own attack power with 98 base Attack added.
