After a few weeks of theory crafting Squeak was nice enough to give me 2 celestias on Lamannia.
The results were sad.
First No AP spent on boosting weapon properties & Celestia working properly with only light damage
Second, Drow AP spent on boosting to hit / damage with racial weapons, Celestia still working properly, only dealing light damage.
Third Warpriest +enhancement bonus to favored weapon, this has broken the Celestia by adding Magic as a damage type.
