Offensive Casting and Accuracy of equipped weapon

[claudius]

Do offensive casting spells use the accuracy of the weapon equipped?  So if you have a feat that adds a bonus to wands then your spells are more accurate with a wand equipped than a bow?  Or a different example if you have a weapon that is enchanted to be more accurate will that also make your spells more accurate or is it only when using the weapon in weapon attacks?

They do not.

[Boeroer]

Only weapon attacks.

 

Medium and large shields however will reduce your spells' accuracy.

Thanks for the responses.
