Blessing (3/10): Some people might disagree with putting so many points in Blessing. So let's me explain my reasoning. If you read through this guide, you will see that the points distribution for Aspersion, Monstrance, Resurrection, Revive, Mass Heal, Exorcise and Stone Skin is good as it is. So the decision here is between Blessing and Sacrament. Since Blessing > Sacrament even later in the game, the obvious choice is Blessing (you will see the reason for Sacrament below). Besides, classes with huge aoe will burn through your Blessing really fast (each mob count as one hit), so having Blessing at high level is very beneficial for them.
v0.5: After spending more time partying with different classes, I feel a level 10 Blessing is overkill in most cases. 60 hit counts (with attributes) is sufficient even at late game. And also you have 7 free points to spend in better skills.
