Adjust reality

You can create a 65 feet long, 0,3 feet wide and 16,5 feet tall wall out of pure energie in an unocciopied place. The wall is transparent, similar to glas but you can clearly see the outline of it. The wall is as strong as steel but can be destroyed with enought force. You can always make the wall smaller and you can create her in the air and turned however you like (similar to a sheet of paper that can hover in the air an you can be 10 feet away from the closet point of the wall at the time of creating it). Once created the wall can`t be moved and until the time runs out, it gets mostly destroyed or the caster ends the spell as an bonus action. You can create several walls at the same time (within the timelimit until the first one starts to disappear). The caster can decide, if the wall is completly smooth or if there are some surface irregularities, which allow creatures to climb or walk over the wall (depending on its positioning).

If you increase the spell level you can increase the length the width and the height by 20% and the duration by 20 seconds per level.
