If two Dazer's Very Difficult Terrain areas overlap and a Trooper without multiterrain moves inside one into contact with the edge of the other, does it immediately end the Troopers movement? In other words, are two overlapping Dazer's Very Difficult Terrain areas still two seperate Terrain areas or effectively one big one?
I mean, I know how I'd play it (they just make one big zone), but I have nothing to show that being the way it's supposed to be played...
I know a particularly janky player in our meta who tried to pass it of to me thusly: Have two dazers deployed next to each other, or close enough that their zones overlap their perimeters almost 25mm of each other. This way, the enemy has to waste 2 orders getting in and out every time. 1) Reach edge, stop. 2) move, reach 2nd edge, stop. This to me seems rather exploitative (given how the zone's rules are not stackable, so no other changes occur), so I wouldn't play it that way. But, just bear in mind some people may rule it this way.
My gut instinct says "read it literally and don't over-analyse it" to which I read that each zone is an individual zone and they do not combine even if they have the same effect.
I would say they don't stack so the overlap is still just Very Difficult Terrain and not the edge of the zone.
