Blood Punch

Make a ranged spell attack with either Strength, Dexterity, or Wisdom as the attack ability (Caster’s choice). All creatures within a 20 foot cone from the caster must make a Constitution saving throw against their spell save DC or take 2d12 radiant damage. Creatures below CR3 have disadvantage on this saving throw.

At Higher Levels. Casting this spell with a slot of 3rd level or higher will increase the damage by 1d12 for every level above 2nd.
  When casting this spell with a spell slot of 4th level or higher, all creatures below CR3 immediately fail this saving throw and are considered critically hit.
