Scarmiglione's first form is relatively weak. He will only use Thunder. The player may want to cast NulShock to protect against this, but do not waste more MP than necessary. The party should be at optimal HP and MP levels when they combat his second form, and no positive status effects such as Haste will carry over to the second battle. When he falls, he will taunt the party and reveal his true form.
“You've given me a fine death! Fine indeed! And only in death you'll know the true terror of Scarmiglione!”
Scarmiglione's second manifestation can be a challenge. He comes with a 3,000 HP boost and the dreadful Poison Gas attack, which can do over 400 damage to the party. He does this often, and the player should remedy it immediately with Healaga. Haste, Temper, and Saber will be of utmost important in this fight, as physical attackers are more effective against Scarmiglione than magic. Since he is undead, Fire and Dia spells will hit his weak spot, but because of his high Magic Resistance, will usually not inflict more than 500 damage. Make sure to heal against Poison Gas and the party should be victorious.
