Geosgaeno 2 Boss Battle Guide


geosgaeno second battle

Weapons Weapons with elemental modifiers (fire strike, water strike etc).
Armors Stone Proof, Death Proof, Auto-Phoenix.


KO Punch Inflicts instant death to a party member.
Stone Punch Inflicts Petrification.
Swallow Traps one of your party members inside Geosgaeno.
Regurgitate Exhales swallowed target.
Kills the swallowed party member if it doesn't struggle
damages the rest of the party = swallowed party member's HP - 1 if it struggles.

Being petrified while underwater will immediately shatter your character.


Immediately use Chocobo Wing/ Hastega to speed up the party and make Tidus spam Quick Hit. Gaeosgaeno has high defense but low HP so the battle will end quickly with elemental weapons.

Make sure not to kill Gaeosgaeno when a party member is swallowed or Gaeosgaeno will deal 9999 Damage to the whole party. This can be avoided with Hyper Mighty G Overdrive from Rikku's Mix.
