You point at a creature within range, unleashing the fury of Chromatic dragons upon it. Make a ranged spell attack roll against that creature. On a hit, the creature is engulfed in multicolored flames, and it takes 8d8 acid damage, 8d8 cold damage, 8d8 fire damage, 8d8 lightning damage, and 8d8 poison damage. If this damage reduces the creature to 0 hit points, it must succeed on a Constitution saving throw or die as its body is ravaged by the spell's energy.
