Again, very helpful. Now I have a somewhat conclusive idea on turning Shadowheart into the holy assassin and face of the party that she wants to be:
8 15(+1) 10 8 15* 14(+2) with * Observant Feat adding +1 to wisdom and +5 to perception
(using respec to change initial attribute scores if necessary)
Cleric(Thievery) 4 / Rogue(Assassin) 3 / Ranger(Gloom) 5
