if you are NOT going the hardcore route......I would build a EARTH MAGE (they're cheap and easy to make) also are you planning to solo the entire time or ould you group catacomb to 65 (this 2nd method is far quicker)

if you are gonna join groups I wouldn't even bother wasting fg on a damage charm...instead focus on good ee HEAL CHARMS.....you can get good exp healing members of the party and it keeps the runs lasting for awhile (just hit the monsters with your staff/dagger when no one needs heal so you can still get the exp)
