Terastallizing is a phenomenon in the Paldea region that makes Pokémon shine and glimmer like gems. Terastallized Pokémon shine during battles, too.
Change your Pokémon's type and turn the tables!
The primary feature of Terastallizing in battle is that it changes your Pokémon's type to its Tera Type. Pokémon don't outwardly show what their Tera Type is until they Terastallize—a fact that you can use to take opponents by surprise in battle. Combining Tera Types with different moves and Abilities can open up near-infinite strategic possibilities.
This Tyranitar, which is normally Rock/Dark type, became Ghost type after Terastallizing.
If a Coalossal combines the Steam Engine Ability with a Water Tera Type, the Pokémon can take less damage and receive a boost to its Speed when it gets hit by a Water-type move.
Tera Blast, a new move that shows its power when the user is Terastallized
Tera Blast is a Normal-type move that can be learned with a TM. When used by a Terastallized Pokémon, it becomes a move of the same type as the Pokémon's Tera Type and displays its immense might. Use it at the right moment to change the flow of the battle.
Tera Blast inflicts damage using the Attack or Sp. Atk stat—whichever is higher for the user.
