As you can see its magic related so you should put wizard on full set or just mix with luck but personally i got wiz on weapon and rest luck.
Anyway to use this class you got to start in this order you can change it but this is my personal one.

Skill 1, 2 ,3,5
Skill 1,5,3

The skill 1 increases your magic damage so that should always go first then you can go 2 ways you can use rank 2 with is just does damage to 1 person when skill 1 is active then 3 to regain hp dmg into mp regain and then go off with skill 5 with is a nuke . I use that just for PVE. The second one is basically raw damage increased damage then drop a nuke and mp regain you could add skill 2 after 3 but its somewhat not really trustworthy because you could end up only hitting maybe 1k or even less at times or even 2-3k it depends on luck. With that i use that if im in PVP or in a group with a healer because it cant heal.

Its a ok and to some people to be a little op (not me) but on bosses like mana golem if used correctly u can rape him with ease but the higher the hp the less likely you will win because no heal and even though the skill 3 converts damage into mp it wont save you from someone like Doom Overlord because of its insane hp bar. Its good at farming as long as you dont use skill 1.

Rating: 7.5/10

Its an ok class and their is alot of better classes that can do its job better but dont get me wrong it can hold its own ground but for 2k not worth it better just bot it and if you do it (legit) dont bother only thing that really makes its higher than a 6 is because of its skill animation

Well this took no real work at all only thing i did was give my personal opinion but besides that if you like it i dont mind doing another class
