portable wall

your group are tired and you just lost the barbarian to a horde of goblins and its the 3rd time you had to come back to town your tired and about to give up adventuring all together
maybe you should of been a dentist instead , but as you get into town you see a new shop

"adventuring made easy " inside you see a gnome artificer by the name of fink

"well do i got something for you and may i add i came up with it my self"
this is what i call a portable wall

it acts like a tower shield but the side open up via hinges and your able to use pilons to nail em in to a wall or a cave or a mine

now they have spike on the front so when the little beasties like gobblins or what have you alk try to push on the ones in the back will be pushing them and crushing there own fighters HA also we added port holes this way spell slingers or spear men or what have you can still stab shoot or burn what ever is infront of them

and here is the best part buy one and get one at half price
