Lucifer (The 4 Heroes of Light boss)

Lucifer's normal attacks are light-element, while the Thunder/aga and Aeroga spells are light and wind element, respectively; hence the need for the two capes mentioned at the beginning of the section. Buff up resistances using Mysterio, but do it often while Lucifer is in the air. Reason being is that Lucifer loves to spam Judgment Bolt, which hits the entire party and drains everyone of 5 AP. Keep your HP totals healthy and go ahead and use up most of your AP, rather than saving it up for future turns, since AP might just get wiped out with a single attack. Focus more on offense, pretty much.
