l am trying to make a homebrew magic item that can  make a shield of light or some kind of energy  Barrier and was looking for a spell that does this but could not find any,so l am posting this for help. edit: i found this homebrew but l am looking for something more official (if there is something.)

 Shield, shield of faith, wall of force. Something like those? You can always change the appearance the spell takes and keep the effect the same.

thanks,l will look into them. edit:shield and wall of force would work great with my  idea,thanks.
