Where do you draw LOS from? The Character or the Cannon? If you draw it from the cannon is the Ballista attack done with Disadvantage if the character does not have LOS but the Cannon does?
Make a ranged spell attack originating from the cannon
I suppose this should go into feedback.A DM might rule that the artificer cannot order the canon attack a target if they do not know where it is, but RAW they do not need a line of sight.
It’s the same wording as the old version.I suppose this should go into feedback.
