Thunder Stone Shard
A Thunder Stone shard is a piece of a Thunder Stone, a stone used to evolve certain Electric-type Pokémon. It can be mined from Thunder Stone ore, found in places with stone at high heights such as Extreme Hills biomes. It can also be obtained as a drop from certain wild Pokémon or by using Forage on stone-based blocks with an Electric-type Pokémon. Nine Thunder Stone shards are needed to craft a Thunder Stone.
