Also, I read in a "newbs guide to km3" that 4 attack slots is really the best "bang for buck" method.

That heal does save pots but it slows down farming so much that you actually lose out on cash that would make up for the spent pots. By that logic, it would seem that 4 attacks is really the best method for sorc. Heal and shield are a waste...but perhaps that only applies to km3?

Forgive my ignorance...I'm quite new.
