A Technical Record (Japanese: わざレコード Move Record), or TR for short, is a type of item introduced in Generation VIII that can be used to teach a Pokémon a move. They are single-use items that are consumed after use, making them functionally similar to TMs prior to Generation V. However, TRs differ in one respect: once a TR is used to teach a Pokémon a move, that move is added to the Pokémon's move pool which allows the move to be relearned at the Move Reminder for free.
In Pokémon Sword and Shield, TRs are exclusively found in the Wild Area, where they can be received as rewards for completing Max Raid Battles, or can be exchanged for watts with Watt Traders throughout the area.
Fling can be used if the user is holding a TR. Its power is determined based on the TR's contained move. If it contains a status move, it will default to power 10. Moves with variable power will also use 10 rather than any of the move's usual power calculations, except the TR for Stored Power will use 20.
