I am going to make the Dexterity roll here, and ask a quick question. Daishain, if Poljen runs through and gets far enough away, will he take more damage this round from the wall? Also, what is the target for the Dexterity save? Thanks.
EDIT: I just spotted the note about passing through it. If he runs to either end of the wall, using his Dash can he reach any enemies?
