Good As Gold

Good as Gold provides complete immunity to all status moves used by opposing Pokemon. This includes every non-damaging move: Thunder Wave, Toxic, Will-O-Wisp, Spore, Stealth Rock, Taunt, Encore, Leech Seed, Haze, and all other status-category moves simply fail when targeting this Pokemon.

The immunity only applies to opponent-used status moves. The Pokemon's allies can still target it with beneficial status moves like Heal Pulse. Self-targeting status moves like Swords Dance and Calm Mind are also unaffected. Damaging moves that carry status-inflicting secondary effects (like Thunderbolt's paralysis chance) still deal damage and can inflict their secondary effects normally.

Good as Gold is the signature ability of Gholdengo, the Steel/Ghost-type Pokemon introduced in Generation IX. This ability is considered one of the most powerful in the game, as it prevents almost all forms of non-damage disruption. Combined with Gholdengo's typing that provides three immunities (Normal, Fighting, Poison), it creates one of the most status-proof Pokemon in the franchise.
