Zap is learned by The Hero at level 25, though his tutor in Hidden Valley planned to teach him the spell sooner, before the village was destroyed by Psaro the Manslayer. The spell functions identically to its Aliahan counterpart, though it costs only 4 mp to cast.
Zap behaves slightly differently in the series from this installment onwards. Specifically, the spell conjures a small lightning storm that targets all enemies instead of a single bolt. The spell casts a mere 6 mp to cast, and deals between 70 and 90 damage.
Zap is learned by investing 48 points into the Hero's Courage skill. The spell will blast all enemies with 40~56 points of lightning damage, and will grows in power once the Hero's wisdom surpasses 65. The spell will deal 72~88 damage (barring resistances) once the character's wisdom reaches 150.
