Clot Snake

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 2 (1d6 - 4) piercing damage. If the target is a humanoid, it must succeed on a DC 14 Constitution saving throw or be infected with a disease—Bloodphage.

While infected, the host starts to feel unwell and its speed is halved. When the host's blood is spilled (by receiving piercing or slashing damage), the spray of infected blood gives birth to 1d4 Clot Snakes that spawn 5 feet from the host. This effect triggers only once per round.
