How to get Hellion/Subject/Hot Rash [HOURS] || ROBLOX (Please read description)

Warning : This is the way of mine.. Using Parting + Zero, but I think theres still others people using Parting too but I don't if the upgrades are the same as other peoples. If you using my way, then It requires you a lot of patience and attempts.
