Sinclair is a tricky Spirit duelist in Deadlock who uses misdirection and ability combos to burst down enemies unexpectedly. Spectral Assistant and Rabbit Hole allow him to control fights at unusual angles and from surprising directions. Best builds prioritize Spirit Power and cooldown reduction to cycle his confusion-based kit as frequently as possible. Sinclair excels in flanking and isolating single targets who are unprepared for his damage windows. He can feel inconsistent against experienced players who track his assistant and pre-position against his angles. A high-upside meta pick for creative players who enjoy unconventional hero designs.
