pretty easy but it was laggy so I died alot
but you you will depend on quest mostly and higher lvls lvl up faster than low lvls
but as a beginner its a bit slow... once again...
you need quests to survive at first
or you can enjoy the grind which is fun due to the controls
oh and about skills
you have to buy the skill books even when you start your character at first, and after the job change you're skill points reset but the skills you bought don't go away. you have to buy the new advance classes skills to raise them.
Like trickster 8D
basicly skills = easier grind
I wasn't able to quest due to language so I looked up stuff on LaTale wiki.jp
There is a decent amount or each quest
