since many sellers are selling individual completions on rs3, would like to know the price of a full 418qp from scratch.

 

I think you're just curious and not some sort of arabian prince, but I'll still quote haha

~5000$ (~3800$ if dying in the process, which should not happen though)

expecting it to take around 3-5 Months with many many hours per day (10-14h a day) + It would be very helpful to purchase a gold membership to gain a lot of loyalty pts for a jot aura so xp gain in herblore/agility/prayer will be easier.
