The value for Void Ray’s movement speed during Prismatic Alignment, after Flux Vanes has been researched, as not been updated to reflect the latest’s patch’s changes
Values before Flux Vanes
Default: 3.85
Prismatic Alignment: 3.85 (-0.96) = 2.89
Values after Flux Vanes
Default: 4.65
Prismatic Alignment: 4.65 (-2.03) = 2.62
The speculation is that the 10% speed increase for the base movement speed increase was not accounted for after the movement speed increase to Flux Vanes was reverted.
