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:

Angry Mine
User self-destructs to cause moderate damage to the opposing party.
 * Anger Ball

Adepts are hit by a barrage of black dust. Resembles the Dark Blessing monster skill. Since the damage is Venus-based, it is likely that the name is actually supposed to be "Black Earth".

Bone Charge
User suffuses itself with an aura of blue energy and charges a target to inflict moderate Venus damage.
 * Skeleton

Breath/Blessing series
Blessing, in this case, is actually a mistranslation of katakana for "breath"; the mistake was corrected in The Lost Age.
