Quake Psynergy series

Quake, Earthquake, and Quake Sphere are a series of Venus attack Psynergy featured in both games. They are among the earliest Psynergy spells the player encounters and masters. It is available to the Squire Class series (Squire onwards). Hence, only Isaac and Felix can use this series of Psynergy.

Psynergy spells
Quake: “Attack with a powerful quake.”: This costs 4 Psynergy Points, has a base power of 12 and has a range of three targets. Three rectangular sections of ground underneath the enemy party jolt upward and retract into the ground quickly, bouncing each enemy once. It is available at level 2.

Earthquake: “Attack with a mighty tremor.”: This costs 7 Psynergy Points, has a base power of 35, and has a range of five targets. Three rectangular sections of ground underneath the enemy party jolt upward and retract into the ground quickly twice in succession, bouncing each enemy twice. It is available at level 4.

Quake Sphere: “Attack with a massive quake.”: This costs 15 Psynergy Points, has a base power of 65, and has a range of seven targets. Three rectangular sections of ground underneath the enemy party jolt upward and retract into the ground quickly thrice in succession, bouncing each enemy three times. It is available at level 14.

Analysis
Quake is among the earliest Psynergy spells the player can try out in either game; it is in both Isaac and Felix’s Psynergy inventories at the start of each game. Earthquake is quite useful very early in both games; it can be put to good use in the Lunpa Brigands boss fight in Vault in Golden Sun and the Chestbeater boss trio in the Kandorean Temple in Golden Sun: The Lost Age. When Quake Sphere is first attained, it is viewed as merely a somewhat strong, cheap, and wide-range Psynergy; it is not as widely used as the far stronger and more expensive Grand Gaia of the Gaia Psynergy series, also available in the Squire Class series.
