CON: At least 30/35/40 at a multiple of 5 for bonus stat. Add CON until you get 2 CON instead of 1 add certain point.
INT: The rest of your points go here.
You will put all your points in CON from level 1 until you have enough CON, then you go full INT. You may want to invest much more into CON (maybe at least 100) for pvp based build.
Do NOT get SPR unless you want it for different reason other than sp regeneration.
