Aurora Beam

You fire a beam of brilliant, multicolored light in a 5-foot-wide, 60-foot-long Line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 2d12 radiant damage, 2d12 cold damage and is outlined in multicolored light. On a successful save, it takes half as much damage only. Until the end of your next turn, affected creatures shed Dim Light in a 10-foot radius and can’t benefit from the Invisible condition.

Attack rolls against an affected creature have Advantage if the attacker can see it.

Until the spell ends, you can take a Magic action to fire a new beam of light.

At Higher Levels. When you cast this spell using a spell slot of 5th or higher level, the radiant damage increases by 1d12 for each slot level above 4th.
