Forest Nocturne's first appearance is as a Dance command used by Mog, and once used, can during the Dance duration use the Leaf Swirl (unblockable non-elemental damage to all enemies ignoring split damage reduction, and with a spell power of 50), Forest Healing (recovery from Blind, Poison, Petrify, Silence, Confuse, Sap, Sleep, Slow, and Stop) and Wombat (non-elemental damage to one opponent, unblockable, spell power of 88). As a Dance, it is learned when Mog fights in a particular location. The dance is associated with three battle backgrounds and it can be learned in the following locations; Forest, Phantom Forest, Phantom Train's battle background, Bomb forest, and Dinosaur forest.
