If you are lvl 14 orso..
And you just got to the Gates of Kryta..
Go outside and kill those nasty Mergoyle Wavebreakers
They give you.. 80 XP at lvl 14 ( I think.. ) and the items they drop are good for.. 400-500 g. a run..
I did this to get to lvl 17 and got about 20k while only lvling up.
Be sure to avoid the Bog skales.. ^^
