After succeeding in the DC 25 Arcana check, how long does a character control a Sphere of Annihilation? I see two different ways that the Sphere's control is decided.
- A character controls the Sphere for only a single movement of the sphere of 5 x Intelligence
- A character in control of a Sphere can move it with an action as long as no one else attempts an Arcana check to wrest control of the Sphere from the original controller.
I ask because the rules are not clear regarding how long you control a Sphere after the original successful Arcana check, and the mention that a creature can 'control' a Sphere per this relevant text.
If you attempt to control a Sphere that is under another creature's control, you make an Intelligence (Arcana) check contested by the other creature's Intelligence (Arcana) check. The winner of the contest gains control of the Sphere and can Levitate it as normal.
