Enemy Abilities (GBA)

Monster Skills are various abilities available only to Monsters in the Golden Sun games, which have a variety of effects. Monster skills range from the relatively weak "Rumble", to the incredibly dangerous "Djinn Storm" and "Formina Sage".

Monster Skills do not cause the monster the loss of PP, and therefore are available to the monster at any time other than when it is asleep or stunned. In addition, like Psynergy, they will generally not miss.

The Monster Skills in the Golden Sun games are as follows in alphabetical order, with a list of the monsters that can use them underneath:
