Does the spell's zone of control move with the caster for the duration of the spell or is it stationary where the caster originally finishes the spell? If it does move with the caster, then wouldn't the caster be stuck in whatever awful weather they try to inflict on someone else?
With regards to the Weather Control Witch Hex, does the hex function exactly like control weather but it takes an hour to cast? Can a witch change the weather after a first type is chosen by spending an extra 10 minutes dancing? Does a witch retain control of the weather for 4d12 hours?
