Should you run the Garchomp / Sylveon Raid Challenge in Pokémon Scarlet & Violet?

Though Pokémon Scarlet & Violet already gave us mice for Valentine’s Day, it hasn’t slowed down in rolling out its weekly Tera Raid spotlight events. Case in point: Garchomp and Sylveon are currently featured as blue star Tera Raids from now through February 19th.

If you’ve been following these events as they’ve gone live, you know what to expect. Garchomp and Sylveon will have boosted appearance rates in Tera Raids at either 4 or 5-Star difficulty. They will spawn as any Tera Type in the game, so it’s impossible to choose a dedicated Pokemon to counter them like in 7-Star raids. That said, Sylveon will more commonly appear with the Fairy Tera Type, while Garchomp will commonly sport the Ground Tera Type. These events typically don’t boost the the appearance of Tera Types that correspond with a Pokemon’s natural Type, so both these monsters may hit you harder than other 5-Star raids. Here’s what to expect.

While both these monsters are strong attackers, their stats and moves are dramatically different.

Sylveon is the easier foe of the two. It’s offenses can be hard to predict, as it knows Hyper Voice, Moonblast, and Tera Blast. Hyper Voice is typically Normal-Type, but if Sylveon has its hidden ability Pixilate, it will deal Fairy-Type damage instead. Similarly, Tera Blast’s Type corresponds with the user’s active Tera Type, so there’s no “safe” Type to always use. That said, Steel shuts down Fairy and Normal moves handily, and it deals Super Effective damage to Fairy Pokemon. Considering Sylveon’s boosted appearance rate as a Fairy Tera Type, monsters like Perrserker and Magnezone can perform particularly well here.

Sylveon’s other notable move is Yawn, which it is prone to use near the start of the fight. This is
