Analysis
Being available early in both games, thorn can prove to be a valuable Venus-based multi-target Psynergy, as it is more powerful than the Quake Psynergy series and available earlier than the multi-target variants of the Spire Psynergy series. Thus, especially in The Lost Age, where the player has access to a Mercury Djinni well before they have access to a Mercury Adept, practically forcing a class-change, this series may see some use.

In Dark Dawn
One of the battle scenes showcased in Golden Sun: Dark Dawn shows Matthew using a Psynergy spell that appears to be a Psynergy from this series in full 3D.
