Focus on MND/CRIT/Determination.
Your 30 character points vary. Some end game SCH just dump all into 30 vit because its better overall than what 30 mind can give you (about 30-40 heal potency.) You can also go 15/15 but the vit is really only "needed" on t5 of coil. I use that term loosely of course but who knows how the class changes will effect the "need" of a certain hp area for that fight and extreme primals.
