Just the d4 result, but it's added to the normal spell casting time.
Also, SK - you get to throw only one fireball per round. I'll let you keep the rolls for the second one if you decide to fire it in the coming round (also the second one penetrates on damage).
Also I don't think there's any sort of ready action in Hackmaster, at least I found none at a glance. Regardless the Elk decided to go after Jace meaning Sho Lee wasted his turn.
Round post incoming soon.
