Terastallization: offensive plan, defensive consequence
In Scarlet and Violet, ordinary Tera Types replace the defensive battle type. Stellar is different: original types still determine matchups, while moves gain type-by-type boosts under separate rules.

A separate type field
Record the individual’s Tera Type separately from its species types. For an ordinary Tera Type, the transformed type determines matchups. Stellar preserves the original type or types for that purpose. A default-form chart and an ordinary Tera assumption can therefore both give the wrong answer if the actual battle state is Stellar.
One resource, several possible turns
The base mechanic allows one Terastallization per battle. Consider whether to use it to strengthen an attack, change a damaging matchup or preserve another option for a later turn. A clever type choice is not enough if the timing leaves the rest of your team without a plan.
Scope of this explanation
The linked official announcement explains the base mechanic, including enhanced same-type attack power. Later DLC interactions and special types need their own current documentation. This article deliberately does not turn an older announcement into a complete rules reference for every expansion or tournament regulation.
Stellar has its own resource rule
The official Stellar explanation describes a boost once for each move type: after a type has been used, another move of that type does not receive that boost. Tera Raid Battles are explicitly different and permit unlimited boosts. This is a battle-state rule, not a permanent nineteenth row added to the ordinary species type chart. Read the specific mechanic before planning damage or defense.
