Hullo. I was was thinking, if WALL blocks everything as it says in it's description. Would it be possible for it to block EMP as well? I was originally going to suggest a new wall type, but I realised that it would probably be better to add the feature to the original wall instead :P
I think it should be better as an element, *could* block EMP blasts in a 4x4 radius, though, pretty much the same as TTAN blocks air.
But that would be an element with only one purpose. Surely that's a lot less likely to be considered than an addition to an already existing element? It kinda makes sense, wall is supposed to block everything right?
I don't think normal walls block EMP blasts.
I like this idea.
Maybe TTAN with a tmp of 1?
