Level up Fast in Dragonfable

At first, getting EXP (experience points) is easy - killing Sneevils will do. But by about level 15, you need a new way to level up quickly.

Steps

In Falconreach's main screen(the one where twilly is), go Far Left.
Pass the Serpent bridge, until you reach the gates of Oaklore.
At the gate, Sir Ano will be standing, talk to him and go over the quest.
Go inside the gate and go to the left.
Talk to the knight standing and do the 'Explore ruins' quest.
Go through the quest, defeating all the vurrman and tuskmongers then the boss.
Go back to middle of Oaklore(where you entered from the gate). Talk to the knight on the right.
Do Rolith's Quest.
Repeat until satisfied with level.

Need a heal? The Doorway to the left is a doctor's surgery. Talk to the guy there and he'll heal you.
Going through the Oasis Inn mini-quest also levels you up in a similar way. (Talk to Zhoom in The Sandsea.)
Do take friends (Artix, Robina, Valencia) if necessary, but they are quite weak and slow down high level characters, Rolith from oaklore is the best to have around as his hits are strong and he will attack stronger if you are a higher level

This will not get you to level 40 straight away. You'll need patience and time on your hands.
