Time For A Raid
Players who have already used their Dusk Stones or cannot quickly get another can still catch one in 5 and 6-Star Tera Raid battles in Kitakami. However, This is more difficult since 5- and 6-StarTera Raids inPokémon Scarlet & Violetare only unlocked after beating the main game, followed by the post-game tournament. Even then, the featured Pokémon in Tera Raids are usually random, so finding a Chandelure ultimately comes down to trial and error.
