I just started a hc solo mage and im wondering how much vit to put along with abilities
Solo Mage is difficult on HC but not impossible.
I'd say at least 75 Vita, and I am even unsure if that's enough. Wearing only robes and being a fragile class will increase the risk, but the reward potential is still nice, Mage can cast like a champ and heal himself so if you are careful it's not too hard.
Try PM'ing
implite and you can tell him I said for you to do so in hopes he has a better answer, he likes to solo mage a lot on HC and would know better than I do as far as how the stat should go.
