I was thinking of Lines of Forbiddance and I realized that they might have the ability to create levitation.
When looking at the wiki, all it says is that they can’t be moved and the wall it creates is perpendicular to its surface. I have questions though. Can the thing the line is on be moved? Can it be rotated? How far does a Line of Forbiddance stretch outward? Does swinging it and hitting something put a force on you or does it just pass through? What if it is initially drawn on the bottom of something or on a slope? Can this make something float in mid air?
Depending of how Lines of Forbiddance work, they could get very powerful, very quickly.
Ps. Does this count as introducing myself?
