The first paragraph of the control winds spell (from Elemental Evil Player's Companion) states that:
You take control of the air in a 100-foot cube that you can see within range. The effect lasts for the spell’s duration, unless you use your action on a later turn to switch to a different effect. You can also use your action to temporarily halt the effect or to restart one you’ve halted.
Does this mean that the spell is limited to the original 100-foot cube for the entire duration of the spell or can you retarget it when you switch to a different effect or halt and restart the effect?
