Several of the books have had battles in areas of volcanic instability and we have rules for magma and breaking through into pools of it. Recently I played MWO which had a map with a molten cauldera at the center with paths around it and while trying to figure out why you were on that map except to have damaging terrain and heat burdens . . . it occurred to me, how many folks include that sort of map on TT?
Does it change what you bring to the fight? Does it change how you advance through the terrain?
Also has anyone made a rough copy of that map for MM?
