In theory, the sub-layer of Arc Bahamut is meant to connect with the prongs of a Forge Disc so that as the Arc Bahamut Combination grows three-quarters of the way to Bursting, the sub-layer moves in order to fill in the six gaps in between the blades and reduce recoil. In practice however, the decrease in gap depth is too minuscule to impact performance in any significant manner.
