The second tip, to learn how to get to 99 Runcrafting, is introducing runecrafters into the Abyss. You have to do the Zamarock mini-quest in order to use it, but that should not take long. The Abyss is a large, underground cave. You can teleport to it by going to the man in the red robe, in around 6-8 wild, northeast of Edgeville. Inside the cave are many creatures of the Abyss. They can do very harmful damage, so it is recommended to pray or bring good armor. These are the creature you can kill to obtain the pouches!
There is a ring center in the middle of the cave. (Take a look at your mini-map.) To get into the center ring, you have to bring the necessary tools to perform a skill. The easiest way is to wood-cutt, thieve, or mine. Once you are in, you will be able to enter one of the rune portals. Every portal is around the inside wall of the circle tunnel. In the middle of the entire cave is a man. Talk to this man and he will repair the pouches for you, as they will degrade and hold less from time to time.
Once you have made you runes, simply teleport back to as close as you can to Edgeville and do it gain, until you reach your goal or even to 99 Runecrafting. The best way to teleport is to use glory amulets and teleport back to Edgeville. If you have ancient magic spells, you can use the teleport to go back to Edgeville with your spells.
Hopefully, with these two tips of this 99 Runecrafting guide can help you learn how to get 99 Runecrafting fast and efficiently. With these tips, there is chance to doubling, tripling, and even quadrupling your experience per hour Runecrafting.
