Copied from my question on the Pathfinder Society Facebeook group, which I was unable to get a confident answer. Correct me if I'm wrong, but the Feat Noble Scion: Scion of War lets you use your charisma bonus in place of your dexterity bonus for initiative. This should stack with the Paladin Archetype: Sword of Valor, which at level 2 adds your Charisma Bonus to your initiative. These stack, right? As one changes your base Initiative and the other adds a bonus to the base initiative?
This is in the FAQ already:
"Do ability modifiers from the same ability stack? For instance, can you add the same ability bonus on the same roll twice using two different effects that each add that same ability modifier?
No. An ability bonus, such as "Strength bonus", is considered to be the same source for the purpose of bonuses from the same source not stacking. However, you can still add, for instance “a deflection bonus equal to your Charisma modifier” and your Charisma modifier. For this purpose, however, the paladin's untyped "bonus equal to her Charisma bonus (if any) on all saving throws" from divine grace is considered to be the same as "Charisma bonus (if any)", and the same would be true for any other untyped "bonus equal to her [ability score] bonus" constructions."
I'm particularily focused on this sentence: "However, you can still add, for instance “a deflection bonus equal to your Charisma modifier” and your Charisma modifier."
I feel that this is what this combination is doing, and should be perfectly legal, thoughts?
