From Bulbapedia, the community-driven Pokémon encyclopedia.
Corrosive Gas (Japanese: ふしょくガス Corrosive Gas) is a non-damaging Poison-type move introduced in Generation VIII.
Corrosive Gas renders the target's held item unusable for the rest of the battle (even if switched out). The Pokémon is still listed as holding the item on the status screen and cannot obtain another item, nor can it restore the item with Recycle or with the Ability Harvest.
Corrosive Gas cannot melt an item from Pokémon with the Sticky Hold Ability, or if it hits a Pokémon's substitute. It also cannot melt a Griseous Orb, Drive, Memory, Rusted Sword, or Rusted Shield held by Giratina, Genesect, Silvally, Zacian, or Zamazenta, respectively.
||The user surrounds everything around it with highly acidic gas and melts away items they hold.
