Ok so basically there is pure vit which is a known value of about like 14 hp per point so most people go full vit. Strength gives I think about 3.6% damage boost so most people will take it for the parry increase and to help buff attack power which scales some of our heals. And then lastly based on your race for example if you were a highlander u could go the 10Dex and 20 vit or 20 strength option. There is a poster that has a guide on here about mining and maxing based on when you have all your gear. Just remember you can always go and reset your stats for 10000seals from your grandcompany so don't sweat it. So for now I would go pure strength or pure vit like 600 more Hp.
