It would be 6P standard for an improvised thrown shot. No AP mod.
Using spread rules, medium spread does -2DV +2AP gives -2 to dodge and can hit two targets within 1 meter of each other.
So, that would be 4P +2ap with -2 to dodge vs. a couple guys.
Wide spread is -4DV +4ap gives -4 to dodge and can hit 3 guys within 1 meter of each other.
So, that would be 2P +4ap with -4 to dodge vs. 3 guys.
Anyway, on with der show.
