What happens if a Sphere of Annihilation touches another Sphere of Annihilation? I see a few possibilities:
- They destroy one another
- The universe turns inside out
- The effect of hitting one with Gate or a Rod of Cancellation occurs
- They merge together into a possibly larger sphere
- One or both silently vanishes
- They ignore each other and phase through one another like nothing happened
Which of the above (if any) is most correct?
