Viper Strike

You reach out and cause a spectral viper to strike at a creature you can see within range.

Make a melee spell attack. On a hit, the target takes 1d8 piercing damage and 2d8 poison damage, and the target must succeed on a Constitution saving throw or have the Poisoned condition for 1 minute. A poisoned creature can repeat it's saving throw at the end of each of it's turns, ending the effect on itself on a success.

Using a Higher-Level Spell Slot. You can make additional attacks with this spell when you use a higher-level spell slot, either at the same target, or another target within range. The number of attacks you can make increases by 1 per level of spell slot above 2.
