rules questions


I have a few questions:
1. For magical damage (like the blasts a Magician of Dessi sends out with his Wizard's Staff) do I add the Magician's Wisdom modifier? I just thought that made sense because all the other forms of combat have their respective modifiers added to damage.
2. When Willpower is gained by a spellcasting class, is it only the die listed in the chart or do they add their Wisdom modifier akin to the adding of the Constitution mod to Endurance gains
Remember you still add in the +2 to damage from the staff being mastercraft and magical.
