Zidane: As I mentioned before, one of the grimoires posions EG, and EG's 200,000 HP means the gradual poision damage factor is 9,999. And perhaps it's because the grimoires' powers are altered with EG because they are meant to be used to make EG an easy battle. I honestly don't believe Square goofed up. Rumor used to have it that the grimoires did that because originally Square planned to have it where if you use all nine grimoires on Zeromus EG, after death he turns into Zeromus XG which was suppose to be where the REAL fun began, which may explain it.
