Fletching darts has to be the fastest way to get a 99 in Old School Runescape. Fletching really picks up the pace once you reach level 37 Fletching, which really isn’t hard to get. It would take you about an hour to get to that. From there you unlock Steel darts, and it takes only 20 minutes from level 37-52, and it will cost you about 400 000 cash. With steel darts you get about 300 000 Fletching XP per hour on average. For those that don’t know, darts are so fast because you are literally the determinant of how fast you get XP. You simply just have to spam click each action, and the faster you click, the more XP you will get. So, with a lot of focus you are going to get a lot of XP per hour. From level 52-67 Fletching, the next thing you can do is Mithril darts, and they give you about 900 000 XP per hour, provided that you’re clicking the whole time. But, more realistically, you’ll probably get about 550 000 XP per hour because you will want to take breaks, and you are not going to be fully focused for that whole hour. Getting form level 52-67 with Mithril darts will take you approximately 45 minutes, which is no time at all.Since Rune Darts are so expensive, I would consider them as one of the unreasonable methods. So, instead, from level 67 all the way to level 95 Fletching, Adamant Darts are the way to go for very fast XP. It’s going to cost you 42 000 000 to get to 95, but you’ll be getting about 750 000 XP per hour, and that’s even considering a few breaks in between. If you were sitting there spam clicking for hours and hours, you’d probably get about 1 100 000 – 1 200 000 XP per hour. But, judging from the 750 000 XP per hour average, it’s going to take you about 9-10 hours to get form level 67-95 Fletching. At level 95, you will unlock Dragon Darts, and from 95-99, it’s going to cost you about 50 000 000, which is kind of expensive. So, for a cheaper alternative, stay with the Adamant Darts. But, for the sake of the fastest XP per hour, you will be getting about 2 000 000 XP per hour doing Dragon Darts. But, it’s usually about 1 000 000 XP because you will probably be taking breaks, unless you want to get Carpal Tunnel Syndrome. From 95-99 with Dragon Darts, it will take you about 3 hours, which is insanely quick for a level 99. So, all in all, you can get from level 37 all the way to level 99 Fletching in only 15 hours, which probably makes it the fastest and most practical level 99 to get in Old School Runescape.
