it depends cause if you start to pass master quest and want to play higher chars
then i would say get some swords and str gear (robes / charms with str)
so that way you can use on
feeder
samurai
paladin
for the rest caster gear would work high EE charms and int gear (staff or daggers and robes)
monk
ninja (cant use staffs)
warlock (cant use daggers)
alchemist (cant use wepons)
then for the only class that those 2 set ups wont work for is HeadHunter (the second to last class you get which takes along time to reach)
axes / EE scales / dex+str wild heal/light charms (they can only use certain armors and charms like other classes)
samurai and paladin and monk dont take long to get to IMO for most people just depends sometimes really after that they take awhile to pass
