I see some ambiguity with the spell Dancing Darkness. What is the consensus on the following?
I take the usage of each in this rule to mean that the light reduction comes from all four orbs.
You create either up to four spheres of darkness that each reduce the illumination level by one step within a 20-foot-radius
This would mean that in an area on which all four radii overlap the light level would be reduced 4 levels.
The restriction on the relative position of each sphere may make this overlapping difficult to control, which I feel was intended because of this stacking of the orbs. With fine light level control coming from the fact that is up to four spheres. You could choose how many to change the light level from −1 to −4.
