At the start of your RuneCrafting leveling journey, you need to finish Rune Mysteries quest that is needed in order to begin RuneScape gold crafting runes. In this manner you skip painful early process of performing atmosphere, water and brain runes. Furthermore, if you've got 46 Magic, 5 Structure and The Grand Tree completed you can do The Eyes of Glouphrie pursuit that will take you all the way to level 23 (if Input the Abyss is finished too ). If you don't need to perform quests you will craft Air Runes.
If you haven't completed The Eyes of Glouphrie pursuit at level 9 you will be crafting Earth Runes that are quickest at this level. Earth Altar can be found north-east of Varrock, only before the Lumberyard. To reach level 14 you need to make around 8 trips. If you would like to earn those quicker you are able to use Varrock teleports and Lumberyard teleports although it is going to cost you a bit more.
Once you reach level 14, you wish to take your rune/pure essences and run to the Fire Altar which is located just north of the Duel Arena. Because of that, you wish to purchase Ring of Duelling which provides you quick teleport into the Duel Arena. Once you run from this location to the Altar and produce your runes you'll be able to teleport to Castle Wars with Old school rs gold the same ring. From the lobby room, you'll find a chest at which you could bank everything you created and choose clean essences for your next excursion. Craft Fire Runes for around 20 excursions and you'll hit level 23.
