Hi Leet! Today im going to teach you how to get to level 99 Runecrafting and get that pretty RC skill cape.
First thing you want to do is travel to Bob at the Skills teleport and purchase a good amount of rune essence.
Next you need to tele back to home because the Zamorak Mage is in level 5 Wilderness.
Grab your full inventory of Rune Ess and away we go! Leave Edgeville via the Wildy. And follow this route.
Next talk to this dude!!
Once you get to him and talk to him (trade does nothing!) and click AIR. Avoid the pesky Skeletons as they make it where you cant talk to mage.
This will teleport you to an air altar. Click on the Altar to turn essence into runes.
BAZZAM! Congratulations,you have advanced a runecrafting level. Level 28!
Teleport back to home and bank your runes and withdraw another load of Essence.
After this you can proceed by leveling up through the runes. Cosmics at level 37, Natures at 44, Laws at 54, Deaths at 65, Bloods at 77, and so on and so forth!
Good Luck on your 99 Runecrafting!
