persona window Spell Mod amount
 

The spell mod amount doesnt include the + spell dmg from the SK buff unhallowed strength.

A considerable number of this data is not exact/does not take into account all modifiers. I just display the data as supplied by SOE, I have no influence over the actual values. Since they chose to not display this data on the Default UI it may never get fixed, but since it's there, I added it.
