You need 45 ranged as a bare minimum required for mystic chinning. You also require around ~1000-1500+ chins per run. We also advise using BIS gear for the best ranged strength & attack bonuses. For the best ranged gear, check out our ranged gear progression guide.
Per run that you order, you will get around 700K ranged XP. The ranged XP per hour will range anywhere from 800K / 1.7M per hour, depending on your ranged level and gear.
