I recently played in a session where Gust of Wind was used in a way I had not seen before, and I wanted to see if my gut instinct on whether that was actually how Gust works.
Gust of Wind states:
As a bonus action, you can change the line's direction.
The line is established in the casting, but I am wondering what the valid choices for direction are. In the session I played, the caster changed the direction of the wind to perpendicular to the original line. See below:
I had been operating under the impression that you could only change the direction the wind emanates from you (the caster). I.E. move the wind from coming out your front to coming out your back.
What are legal changes to Gust of Wind I can make using the bonus action clause?
