Black Crystal Tera Raid Battles contain much stronger Pokémon than those appearing in ordinary Tera Raid Battles, and give out better rewards. To encounter these Pokémon in Black Crystal Tera Raid Battles, players will need to download the latest Poké Portal News. If players have connected their Nintendo Switch system to the internet while playing Pokémon Scarlet or Violet, this will happen automatically. Players can also manually download the Poké Portal News by selecting Poké Portal from the X menu, and then selecting Mystery Gift, and then Check Poké Portal News. After that, players who have completed certain post-game events will be able to start the Black Crystal Tera Raid Battle simply by walking up to and interacting with the Black Tera Crystal in-game. In the overworld, the Black Tera Crystals associated with these raids can be differentiated from other Tera Raid crystals by their aura and black sheen. Both are also clearly visible when looking at crystals on the map. Players who haven't yet completed the required post-game events can still participate in these Black Tera Raid Battles, but only by joining with other Trainers in multiplayer, such as by using a Link Code. A paid Nintendo Switch Online membership is required to participate in Tera Raid Battles with other Trainers online.
