Bite of the Cobra

5th-level transmutation

Casting Time: 1 bonus action

Range: Self

Components: V, S

Duration: Concentration, up to 1 minute

Venomous fangs sprout from your mouth, granting you a bite attack with which you are proficient. The next time you hit with the bite attack, you deal 1d6 piercing damage and the target must make a Constitution saving throw. On a failed save, they are poisoned for 1 minute and must make a death saving throw at the start of each of their turns, even if they have more than 0 hit points. If the target fails three death saving throws during this time, they die from heart failure. A successful Wisdom (Medicine) check against your spell save DC made prior to death stabilizes the target.
