Previous Tera Battle raids featured Pokemon such as Blissey and Typhlosion. These battles provide players with a handful of rewards, including Tera Shards, and the occasional opportunity to obtain the Pokemon appearing as part of the event. For example, the Typhlosion raid allowed for people to capture the Pokemon Silver and Gold starter through the event itself. Other starters players could obtain were the standard versions of the three from Pokemon Legends Arceus.
Tera Raid battles are similar to the raid battles found in Pokemon Sword and Shield. Several players can challenge a specific Pokemon to obtain Tera Shards and capture the Pokemon in question. however, these battles have a unique gimmick that will test even the hardiest of teams.
Pokemon Scarlet and Violet are available on the Nintendo Switch, and the Walking Wake and Iron Leaves Tera Raid re-runs will begin on May 1, 2023.
