It has been quite a while since I have tried to cast it, has it changed in recent times?
I don't recall that it offered an option to cast it on someone else the last time I tried.
On a separate note, WHY would any noble take the time to cast a scroll on "a lowly commoner"?
Seems to go against the general feeling of how commoners should be treated.
Think of how commoners should be treated, and then try to reconcile that with nobles giving a handful of them dozens of scrolls to go blast another realm from existence.
How commoners should be treated and played has little to do with how they actually are.
