Luck

Luck is a character stat in both Golden Sun games. It decreases your chance of being inflicted by a status inflicting problem attached to an ability used against you, such as Sleep and Stun. However, it does not increase your own chance of inflicting said status effects onto opponents, contrary to common belief.

Unlike your other Statistics, Luck does not increase as you level up. Luck cannot be temporarily changed during battle as well. The only way you can permanently boost an Adept's Luck is by using Lucky Pepper on them. That or setting a Djinni on them or equipping luck-boosting equipment that boosts luck.

Having a luck rating of 40 or higher provides immunity to Poison, Venom, Haunt, Death Curse, the target's HP being instantly reduced to 1, and being forced out of battle (Like the Djinni Gale's attack would otherwise have a chance of doing).
