Maybe I'm just tired, but I'm struggling with a concept here. If I cast an attack spell that has the additional effect of lightning, and choose to add the autofire quality to it, my spell difficulty is 3 purples.
Do I need just 2 advantages to activate all the elements of lightning (i.e stun AND one extra hit of autofire), or do I need 2 adv for lightning, (which gives the spell the stun quality), and 2 adv per extra hit of autofire?
Or something else entirely?
My sleepy brain thanks you in advance.
