Tera Shards are items introduced in the game Pokémon Scarlet and Violet that allow players to change a Pokémons Tera Type. To change a Pokémons Tera Type, players must collect 50 Tera Shards of the desired type. Tera Shards can be acquired by completing Tera Raid Battles of at least 3 stars, which may yield Tera Shards that match the Raid Bosss Tera Type. Higher-difficulty Tera Raids tend to yield more Tera Shards upon victory. Tera Shards may also be found occasionally in the overworld as hidden items. In the game, Tera Shards are most commonly acquired by battling Terastalized Pokémon, which can drop Tera Shards of their Tera-Type when defeated. Once a player has enough Tera Shards of a certain type, they can change their Pokémons Tera-Type by speaking to an NPC at the Treasure Eatery in Medali.
