Unlike most role-playing games, status effects are based on a three-pointed emotion system.[8] A party member or opponent's emotion can change throughout the course of a battle, usually due to moves by another party member or enemy.[5][2] Neutral is the baseline and has no effects, Angry increases attack but lowers defense, Sad increases defense but lowers speed, and Happy increases speed but lowers accuracy.[6] Emotions are either strong or weak against each other – Happy beats Angry, Angry beats Sad, and Sad beats Happy. Additionally, higher-intensity variants of each emotion also exist.[1]
