As with Gades on Shuman Isl., hit the light weakness with Arty's Fry or Zap, Maxim's Silver sword, or Selan's Super sword or Holy whip
Uses Chaos wave on turn 1 and every 4 turns after. It's a non-elemental attack on the whole party (power 350) with a 35% chance of confusion.
Confusion is prevented by the Jute helmet (Maxim, Guy), found on Tanbel Southeast Tower 5F, the Power brace (Maxim, Selan, Arty), found on Alunze Northwest Cave B3, and the Ghostclothes (all 4), found on Tower of Truth 4F. If confused, cure it with Shriek or the IP skill Revival sleep on Arty's Silver robe.
On the 3 turns in between, it uses Thunder (thunder) or Ice Valk (ice) on the whole party, Galactic lancer, a non-elemental attack on the whole party (power 600), or a normal attack
Chaos wave, Galactic lancer, and normal attacks are reduced by the target's DFP and by Defend. Raise DFP with Courage or Forcefield on the Zirco gloves, and reduce the 2 non-elemental skills with Power guard on the Gauntlet (user only)
Spells aren't reduced by DFP or Defend. Thunder guard on the Plati gloves (Selan, Arty) from Barnan's weapons shop reduces Thunder, and Ice guard on the Plati shield (Maxim, Guy) reduces Ice Valk (user only)
