Thread Storm is a powerful area-of-effect multihit attack in Hollow Knight: Silksong, acquired in the latter half of Act One in the Greymoor area. To maximize its effectiveness, players should rapidly mash the right bumper to extend its duration without consuming additional silk, though this increases vulnerability to counterattacks. The ability is particularly useful against bosses and in challenging wave fights. To find Thread Storm, players should go east past Shakra, enter a building at a dead end, and complete a wave fight to access a shrine containing the ability.
