The Ruin Guard is a boss from Grandia. It is encountered in the Zil Padon Ruins. The Ruin Guard appears alongside Ax and Boomerang which together form the whole monster. The Ruin Guard body has the ability to cast Healer and Zap!.
Ruin Guard will use Zap! with the main part of his body which can deal heavy damage but this can be cancelled easy enough. The Ruin Guard has a small resistance to all magic varieties but this will not effect damage values that much.
