# [Shadow Mastiff Alpha](Rules\Source\bestiary\monstrosity/shadow-mastiff-alpha-mpmm.md) *Source: Mordenkainen Presents: Monsters of the Multiverse p. 215* Each pack of shadow mastiffs is led by an alpha, the smartest one of the group. The sound of an alpha's howl strikes terror into those who hear it and is a sure sign that a pack is on the prowl. ## Shadow Mastiffs Shadow mastiffs—hounds of the Shadowfell—move invisibly through the shadows, always on the hunt. ```statblock "name": "Shadow Mastiff Alpha (MPMM)" "size": "Medium" "type": "monstrosity" "alignment": "Typically Neutral Evil" "ac": !!int "12" "hp": !!int "44" "hit_dice": "8d8 + 8" "modifier": !!int "2" "stats": - !!int "16" - !!int "14" - !!int "13" - !!int "6" - !!int "12" - !!int "5" "speed": "40 ft."
