Soo im realy in doubt about that, i have 15 skill points to distribute between aspersion blessing and sacrament. i Found myself with 3 options:
1- aspersion lv10 (40% physical defense), blessing lv5
2-blessing lv 10, sacrament 5
3- aspersion lv5, blessinc lv5 , sacrament lv5
reminding that blessing had got a little bit stronger after the last update
im tempted for getting the frist option, because i like making my party more tanky, but i dont know what is more useful for late game.
just for information, im clericC2,PriestC2,PaladinC1 (future paladin C3)

Your party can buy max level Aspersion and Sacrement from Pardoners that will last a whole lot longer and be stronger than anything you can provide with the options you have listed above, but due to the new blessing formula that takes into account the caster’s stats you have a blessing that cannot be replicated anywhere else.
