A little dangerous, you may need dex up or def up scroll

Now you are a magician!! Hunt Crawford until you reach 72-73. Move to buy Airrivals Gold Gorge of Silent, hunting apes and golems as you notice that crawfish don’t give you so much exp anymore. AVOID Grand Master Golem (GMG) at early 70.

Hunt Apes collect them and kill them at once with Ice-bang+wind-storm/Tornado. You can also solo Master Stone Golem (MSG) for 11k exp, just stay away from his melee range.

If you are bored, change place to luna and go kill some slags/wolves. You need a tank though, best is a knight or a raider (with high dodge). You can also team up with a cleric (with defense aura), so that both of you can tank. Luna is a good place for making money.

Where I train after level 80:

Goblin cave b3: a little dangerous, you may need dex up or def up scroll, but essences are dropped like rain here

Gorge of Silent (Top north Grand Master Golem Spawn): over 20k exp for 1 GMG and chance to get sporty drawing / unique

Luna: Crystal Plateau/Arumic Valley> Gemstone and refine material

Luna: Temple 1

Pretty pricy, eh? I hear it's pretty hard for muses to collect Union pts. So it "may" be a better idea for them to buy the parts.
