Discus of light (Andy)

 "Where light begins it shall return, all things return."

You launch forth a holy disk of light, piercing foes but stopping on physical objects. All creatures that the line crosses must make a dexterity saving throw or take 1d6 radiant damage. On initiative count 20 the disk returns, hitting creatures again in that line.

*Note from creator. The (Andy) is in reference to a character that created this, be sure to talk to your dm if you can use these as they are incredibly untested!
