The Ability Moody will cause its user to increase one Statistic by two stages whilst lowering a different Statistic by one stage at the end of each turn. Any Statistic can be increased and/or decreased, including Accuracy and Evasion, but Statistic increases and/or decreases won't exceed the allotted limits.
Moody doesn't have an effect in the Overworld.
