Ayailla's radiant burst

Shards of holy energy shoot out from your finger tips in a 60 ft cone each creature within the radius must make a Constitution saving throws or  take 3d6 radiant damage half as much on a successful save and creatures of evil alignment that fail the save are blinded for one minute and can remake the save at the end of their turn. 

Any evil aligned creature that casts this spell takes 1d12 radiant damage. 

At higher levels above 2nd level deals an extra 1d6 damage per spell slot higher.
