Stellar Tera Shards are a key item connected to the new Stellar Pokémon Type in Pokémon Scarlet & Violet's latest DLC, The Indigo Disk. The Stellar Type is a new and unique Pokémon Type that only appears when you Terastallize other Pokémon with 50 Stellar Tera Shards. A Stellar-type Terastallization will make your Pokémon super effective against other Terastallized Pokémon, making Stellar Tera Shards a game-changing addition.
