Cobra Strike

A spectral cobra appears above you and spits a
stream of poison at the eyes of a creature you can see
within range. Make a ranged spell attack. On a hit, the
creature takes 4d10 poison damage, and it must make a
Constitution saving throw. On a failed save, the creature
is blinded and poisoned until the end of its next turn.
On a successful save, the creature takes the full damage,
but isn’t blinded or poisoned.

At Higher Levels. When you cast this spell using a
spell slot of 4th level or higher, the damage increases
by 1d10 for each slot level above 3rd.
