Plasma Psynergy series

The Plasma Psynergy series is one of the strongest and most popular groups of Jupiter Psynergy available. It receives heavy usage throughout the series, as each level of the technique is very powerful for when it learned and retains much of that power for a long while afterwards. The final variation, Spark Plasma, is considered to be the ultimate power for the Wind Seer Class series, although the Hermit, Jupiter-based Pilgrim and White Mage Class series can also use it. As such, all party members other than Venus Adepts can use this series of Psynergy. It is described as an "Attack with a barrage of bolts".

The Plasma Psynergy series is very similar to the Thunderclap Psynergy series used by the Ninja Class series.

Psynergy spells
Plasma - Strike with a barrage of bolts - It appears as a single bolt of purplish-white lightning firing down on the enemy before exploding on impact with the ground. Plasma is learned at Level 8, hits three targets with Jupiter power of 45, and costs 8 PP to perform.

Shine Plasma - Strike with a concentrated flurry of bolts - It takes on the form of three individual Plasma attacks striking in succession. Shine Plasma is learned at Level 26, hits five targets with Jupiter power of 100, and costs 18 PP to perform.

Spark Plasma - Strike with a coruscating surge of energy - Unlike the other members of the series, Spark Plasma's animation experiences a notable change between games. In Golden Sun and Golden Sun: The Lost Age, it appears as a barrage of normal Plasma attacks being volleyed without ceasing into the targeted enemies. As of Golden Sun: Dark Dawn, it resembles a thunderbolt crashing into the opposing party and forming a glowing orb of energy that ultimately explodes, causing the screen to fade to white. Spark Plasma is learned at Level 50 for the Wind Seer, Hermit, and Pilgrim Class series, and Level 46 for the White Mage Class series. It hits seven targets for Jupiter power of 180, and costs a tremendous 37 PP to perform. Although Thunderhead looks similar, Spark Plasma is weaker than Thunderhead. However, Wind Seers have more buff and debuff Psynergy than the Ninja, which can help to compensate for the difference in power. Which one players use is largely a matter of preference.
