From Dragon Quest Wiki

Co-Kaswooshle is the strongest Wind pep power, capable of slicing through steel with twin tornados.


Dragon Quest XI: Echoes of an Elusive Age[edit]

A pair of Godsteeds will cast Co-Kaswooshle and deal an average of 350 Wind damage to 2~4 party members in the game's 3D mode and the entire party in 2D. The pep power has a tremendously wide damage range typical of the Woosh family of spells.
