Please Help with shield wall build

Do the shield wall explosions overleap (with ahn`s citadel + kaon`s madness gems)? The fissures can shotgun monsters?

Cant find this information anywhere in any guide. =/

I tested it as I never think of this interaction and... Unfortunately, no they don't overlap. I was even doing a bit less with Kaon's Madness because of the 20% less damage.

That being said, it make Shield Wall a surprisingly "good" clearing skill as it cover the whole screen (and even beyond). I still prefer his ability to nuke Boss and clearing with Resonating Shield but it's an option. ^^
