Iron Leaves, a Paradox form of Virizion, is one of the two Legendary Pokémon recently introduced in Pokémon Scarlet and Violet. While Iron Leaves is exclusive to Pokémon Violet, players of both games can join forces to participate in raids and catch this new Pokémon.
Although a five-star raid can still pose a challenge, it is not as difficult as the occasional seven-star event raids. However, Iron Leaves is still more challenging than its counterpart, Walking Wake.
Defeating Iron Leaves in a raid will yield standard rewards such as Exp. Candy, Tera Shards, Bottle Caps, and valuable treasure items that can be sold for money. The complete list of drops can be found on Serebii.net. It's worth noting that Iron Leaves raids do not have a chance of dropping Herba Mystica.
Iron Leaves is a level 75 Legendary Pokémon with a Tera Type and Psychic abilities. Its moveset includes Psyblade, Leaf Blade, Megahorn, and Swords Dance. In battle, it will initiate Electric Terrain, triggering its Quark Drive ability that boosts its most proficient stat in electric terrain.
The usual counters for psychic-type Pokémon, including bug, dark, and ghost-type moves, are effective against Iron Leaves. However, its Megahorn move can be super effective against dark-type Pokémon, so caution should be exercised when using them.
Iron Leaves is a formidable opponent, especially when it uses Swords Dance to increase its damage output. Consider using a Pokémon with Clear Smog or Chilling Water to debuff Iron Leaves and bring it back to normal damage levels.
A maxed-out Pokémon is not necessary to defeat Iron Leaves, as long as your Pokémon can either withstand a few hits or debuff it. A Skeledirge with its ghost- and fire-typing proved effective against Iron Leaves. Other players have reported success with Ceruledge, a fire- and ghost-type Pokémon, and Gholdengo, a steel- and ghost-type Pokémon that is resistant to all of Iron Leaves' moves.
