The Mammon Machine's stats change based on the attacks that hit it. Players will have about two rounds to damage it before it begins unleashing attacks. It is ultimately best to defeat it before it can use its first attack (an Energy Release that is far more powerful than in vanilla, so be careful), but that's not always feasible.

Hitting with physical damage will raise the machine's physical defense, while magic will raise its attack power. If Frog has the Grand Leon, auto-attacking with it will reset the machine's stat changes.

After the Energy Release, the Mammon Machine's stats will remain reset and it will attack with a very powerful single-target Point Flare, which can down most characters even at full health. Then it will begin its cycle again. While this can be a quick fight that players survive by narrow margins, doing so can prove problematic because there is no chance to use the menu or heal between this fight and Zeal 2, and she will immediately start damaging characters. Try to finish the fight with high or full HP.
