Haven't played much since the updates rolled out. But I heard that the EX rings only work against certain explosives? Like they don't reduce against flamethrower, mines, etc? Haven't tested, but I'd love for the EX rings to at least reduce damage against ALL explosives. If the item in question can NOT be used in an EX room, then EX rings should reduce their damage.
Didn't realize the buff in nades. It does seem kind of "neutralized". In the sense that the extra damage given to the nades basically equals out to the reduction from the rings lol. I tried double stacking the EX rooms in an A&D where the majority of players were using explosives and didn't see much of a difference?
