Am I missing something here, or are there no rules in ArM5 for determining when magi cast spells in a combat round, with the exception of fast-cast spontaneous spells? At the moment I'm assuming that getting magi to roll Qik+Finesse for formulaic/regular spontaneous spells while everyone else rolls Qik+weapon Init bonus is the way to do it, but should it be handled any differently?
EDIT: The answer in on page 174 upper right column. Magic and enchanted items use Qik + Stress Die only. Fast Casting and certamen are special cases where one adds Finess.
Whoops!
Can't imagine how I missed that.
