Upgrading With Skill Points - Assassin Class

I'm wondering what I should use my skill points to upgrade. Strength, dexterity, intelligence, defense, or agility?
Class: Assassin

 

Dex/agi/int it depends on your build. If you don’t know what kind of build you will choose put points into whatever helps you wear armor at your level (and int, I guess. Go for spells (spell cost goes down the more int you have)before finding a build you want to stick to).

 

Keep in mind that intelligence only reduces spell cost at specific skill point amounts: http://www.wynndata.tk/mana/
