Death DogMedium monstrosity
Maneuvers. The death dog uses maneuvers (maneuver save DC 12). It has 2 stamina dice which are d8s, a dice limit of 1, regains all expended stamina dice when it finishes a long rest, and regains half its total stamina dice when it finishes a short rest. It knows the following maneuvers:
Two-Headed. The dog has advantage on Perception checks and on saving throws against being blinded, charmed, deafened, frightened, stunned, or knocked unconscious.
Bite. Melee Weapon Attack: +4 to hit, reach 1 m. Hit: 5 (1d6 + 2) piercing damage. If the target is a creature, it must succeed on a DC 12 Fortitude saving throw against disease or become diseased. Every 24 hours that elapse, the creature must repeat the saving throw, reducing its maximum health by 5 (1d10) on a failure. This reduction lasts until the disease is cured. The creature dies if the disease reduces its maximum health to 0.
As an action, you can make a melee weapon attack and a Brawn check to grapple the creature.
You can add the stamina die to the attack’s damage (add half if you miss by 4 or less) for each additional stamina die expended.
As an action, you can use the Dash action. If you move at least 4 meters straight toward a creature, you can make a melee weapon attack against it. Add the stamina die to the attack’s damage (add half if you miss by 4 or less).
You can increase the damage for each additional stamina die expended.
