Ok so my question is this, I cast chill touch as part of my spell strike. It has multiple charges i dont use all of them in this turn. Next turn can i use spell strike again to also then cast Shocking grasp and hit with both my remaining charges of chill touch and with my shocking grasp? Or can i only have one of the two spells active at a time? Meaning casting Shocking grasp dispels chill touch or i just cant cast shocking grasp until my chill touch charges are spent?
