Horrific Bite

Melee Weapon Attack: 1d6+4 piercing, disease infection happens when attack roll is 4 higher than target AC. This does require a successful grapple check, with advantage when the target is flanked. The infection inflicts 6 disease damage per day for 3 days, long rest is impossible, only a Greater Restoration spell can remove the disease. If the target dies during the 3 day period, they will rise as a Shambler and attack any living creature in their vicinity. On the third day, if untreated, the victim is human, and they had to make death saves over the recovery period, there is a chance to transform their race to an Ender (players can make this choice, NPCs are 50% chance or at discretion of the GM).
