Heartseeker is a powerful Marksman ability for Rogues in Diablo 4 and the centerpiece of the classs most popular current build. After the Twisting Blades nerf before the launch of Loot Reborn, it appeared that Rogue players had fewer endgame options than ever, but Heartseeker has quickly emerged as a premier build. With the right gear, aspects, items, and rotation, Rogue players clear out enemies and bosses faster.
