Unlike at Gordovan West Tower, losing here means total defeat
Half of its actions are Destructo-wave, a non-elemental attack on the whole party (power 350), and the rest are normal attacks. Uses no spells.
To hit its light weakness, Arty can learn Fry (40000G) at Eserikto's spell shop or Zap (65000G) at Durale's spell shop
Give Maxim the Silver sword from Durale's shop, and Selan the Super sword, found on Tower of Truth 2F, or the Holy whip, found on Divine Shrine 3F, to make normal attacks light-element. Arty can also make her normal attacks light-element with the Silver rod from Durale's shop.
Both Destructo-wave and normal attacks are reduced by the target's DFP, and damage to party members using Defend is also reduced. Raise DFP beforehand with Courage (5000G) from Dankirk Kingdom's spell shop or the IP skill Forcefield on the Zirco gloves (Selan, Arty) from Narvick's shop.
The IP skill Power guard on the Gauntlet (all 4) from Durale's shop reduces the non-elemental Destructo-wave (user only)
