Good exp here you will find alot of groups at Qufim Island… you need to get to Jeuno at level 20 if your not already there.. At the bottom of port jeuno is Qufim Island here is what you do

you will need a full group for this

WHM, BLM, 3 Bashers(1 thief), RDM

Do's:
-Goto Qufim Island and only fight Worms nothing else, everything else will kill you or give you bad exp
-If you don't have a map it is relatively easy to find the pond just head straight out of the canyon and you will run into another canyon follow that to the pond
- The pond will be loaded with worms and clippers watch out worms are aggro don't take one more than 1 at a time
- Good skill chains are Liquification and Fusion
- Make sure to cast signet^^

Don'ts:
-Don't get close to the following monsters Giants, Wights, Banshees, Acro(leech looking dus), and Dancing weapons. If you get near they monsters they will all kill you really fast.
-Don't goto the pond during 20:00 - 4:00 during that time is night time and you will surely die..
-Stay in the pond area during the day because there are random spawns that will own you..

good luck
