Desna's Shooting Star and Arcane Insight

[Jurassic Pratt]

So I've got an interesting quandary for the rules forum tonight.

Would the divine fighting technique feat Desna's Shooting Star and the Magus Arcana ability Arcane Accuracy stack?

Desna's Shooting Star wrote:

You can add your Charisma bonus to attack rolls and damage rolls when wielding a starknife. If you do so, you don’t modify attack rolls and damage rolls with your starknife with your Strength modifier, your Dexterity modifier (if you have Weapon Finesse), or any other ability score (if you have an ability that allows you to modify attack rolls and damage rolls with that ability score).

The magus can expend 1 point from his arcane pool as a swift action to grant himself an insight bonus equal to his Intelligence bonus on all attack rolls until the end of his turn.

I'm of the line of thought that since Arcane Accuracy is not directly modifying your attack rolls with an ability score (like weapon finesse), but is instead granting you a insight bonus equal to your INT score that it would indeed stack.

However, I'm curious to see what the majority opinion of the board is.

I would agree that the text of Desna's Shooting Star is referring only to direct modifications, such as Elven Battle Focus or the 3.5 guided weapon special ability. Arcane Accuracy is easily far enough away from that for me.

However... expect table variation. The pedantry is real. ^_^

They would stack. The magus ability is not adding an ability score to the roll but rather adding an insight bonus equal to the modifier.

I would say they stack because Arcane Accuracy is meant to stack with Strength/Dexterity bonuses to attack.

RAW you could argue that Desna's Shooting Star bars any other ability score from being added to attack or damage, but you could also argue that since it is worded as "attack and damage" only effects that modify both would be barred.

You're adding an insight bonus. Insight and Charisma are different types, thus they stack.
This example was shown to work in the FAQ when they reference the paladin and how getting a deflection equal to cha would stack with cha to AC.
