The Gaia Core is the final boss in Grandia. The core and its component parts form the root of Gaia, as evolved from General Baal. It is encountered inside Gaia itself, the final dungeon of the game. The Gaia Core appears alongside two Mega Gaia. The Gaia Core has the ability to cast Fireburner, BOOM-POW!, Crackling, Zap! All, Quake and Alhealer+.
Possibly the hardest battle in the game which is not helped if your team have depleted SP and MP from the previous battle. The Gaia Core is very durable and has a HP set at the limit of 9999. In addition to this all parts of the final battle have a varied resistance to all magic.
The player will want to throw their best attacks at the boss until it falls, Liete can help with healing when needed. The player should try to eliminate the Mega Gaia before they spawn Gaia Tentacles, when multiples are summoned they can deal devastating damage to your party.
