A beam of celestial energy that strikes down anyone within sight. Make a ranged spell attack against a target. On hit, target takes 1d8 radiant damage.

For each 2 points of difference in the Charisma stat between the caster and the target roll an additional d8 dice for damage. Example: (If a creature has 10 CHA and the caster has 16 CHA the caster then rolls 4d8 radiant damage instead instead of 1d8)
