Heat Wave and Liquifier (sic) are two of the more powerful single-target Psynergies available. They are usable only by Garet in his Guard Class series, and are generally considered to rival Ragnarok and Odyssey in usefulness. It is utilized in Golden Sun: Dark Dawn by Garet's son, Tyrell, in his base classes. The word "Liquefier" is meant to be spelled with an E; it is misspelled with an I in Golden Sun: The Lost Age. The spelling error was corrected in Dark Dawn.
