Diviner's Ray

You create three simmering rays and hurl them at targets within range. You can hurl them at one target or several.

Make a ranged spell attack for each ray. On a hit, the target takes 2d4 radiant damage.  If the spell hits, shadows gather around the target allowing others to see a few seconds into the future of where the target will be moving giving advantage to the next attack.  The shadows immediately dissipate once the target is attacked. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you create one additional ray for each slot level above 3rd.
