Another technique to level your runecrafting

First you need to get 50 runecrafting the old fashioned way. There are some tricks you can do like have multiple people bring you essences and you just stand at an altar but that was made more complicated by the trade limit. You can still do it if you have a ton of cash on you and pay people for every trip and tip them slightly so it's worth their time.
Another technique to level your runecrafting skill quickly before 50 is to use a ring of dueling. This shortcut was a slight oversight by the makers of Runescape. Go to the duel arena with it and then run to the extremely close fire altar and make your runes then use the ring again to teleport to castle wars, which lands you about 8 steps from the bank chest. You can dump the runes and get more essences there than teleport back to the duel arena and repeat the process over and over.
Once you finally do get to 50, you can do the biggest shortcut ever. Go to the runecrafting guild which you can access via a purple portal on one of the upper floors of the wizard tower near Draynor. If there aren't many people there, you'll have to switch to the official Great Orb Project server. Once there's a enough people, you can join a game. Hopefully your team will win but either way, you'll get some tokens at the end. If you're lucky enough to have some of the other team members quit or disconnect or if they just plain suck, you'll end up with A LOT of tokens.
