ハードロック (Solid Rock)

Solid Rock provides valuable defensive utility by reducing the damage of super-effective attacks by 25%, effectively turning what would normally be double damage into 1.5× damage. This damage reduction applies to all super-effective moves regardless of their type or power, making it particularly valuable for Pokémon with multiple type weaknesses. The ability functions identically to Filter, offering the same mathematical damage reduction through a different name.

The ability proves especially beneficial for bulky Pokémon that already possess decent defensive stats but suffer from unfortunate type combinations. Rhyperior, despite its impressive physical bulk, appreciates the cushion against its quad weakness to Water and Grass moves, while Carracosta can better survive Electric and Grass attacks that would otherwise threaten its defensive presence. Camerupt similarly benefits from reduced damage against its Water weakness, though its lower overall bulk means it still needs to be cautious.

In competitive play, Solid Rock transforms potentially devastating super-effective attacks into more manageable threats, allowing these Pokémon to potentially survive what would otherwise be guaranteed knockouts. This can create opportunities for counterplay or simply provide more reliable switching options. The ability works seamlessly with other damage-reducing items like berries or moves like Substitute, stacking multiplicatively to create surprisingly resilient defensive cores.
