Vault has the right idea.
Vitality: 0
Strength: 0
Dexterity: 0
Intelligence: 2
Wisdom: 2
Chance: 8
Given that these stats are only improving the stats we already have, Chance gives the biggest gain in improvement of life per point spent and one could say that the value of each point of Chance increase with each point added due to the increased luck. Next I would say Intelligence and Wisdom are tied in value, in some cases I might want one more than the other, but over a long period an even spread probably works best. Vitality would probably be worth putting a point or two in at some point just to insure a decently healthy life, but then I would go back to Intelligence / Wisdom. Strength and Dexterity offer the least value per point.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
