Legend of Legaia Lapis Secret Boss Battle

Secret or optional boss in Legend of Legaia, and the hardest boss in this game. Maybe this is the minimum level to survive its attack, and you have to equip accessories that defend against Light (such as Luminous Jewel or Light Talisman, you can see the beginning of the video) to decrease the damage from Lapis (thanks to the walkthrough from GameFAQs by Meth962). So with this, you can see Vahn survive (almost die) from Lapis's attack even without spirit. Other than that, just my usual strategy when fighting the boss.
Also, this battle without using Point Card, War God Icon, and run away first using something fish (I dunno never get that "fish" item) so you can get back the MP when encounter Lapis again.
