Hmm this is what i should do if i where you,
I've had a full int spear nuker with the same build as yours and i know you'll die pretty easily before you reach 70. I would suggest you to wear armor or prot until you get to d10 then you should wear garment. Spear nukers with garment on d10 are op believe me

the damage from other nukers will be weak on you, you can also grind on higher lv mobs because you got a decent amount of hp. So choose prot until d10 make the other stat points full int. and you'll have a pwner build later on trust me
