I think we might have a different definition of "friends."
S'Mon- "Nunly the half-wit... My friend, these shadows may be ravaging us, but you shall lay down your life that I might escape. Whilst they are feeding on your lifeless corpse, I shall drink ale and recount your glories!"
Nunly- "Ummmmmmmm .... okay."
If the other two hadn't fled it would have been a TPK and killed the campaign. They'd already
lost too much STR drained to have much chance. The barbarian tried to carry his friend out, I ruled he could carry him with STR 9+, the shadows' opportunity attacks then drained him to STR 8. It was not their day.
