Garlycanthrope

Wondrous item, uncommon
  Originally commissioned by an infamous vampire huntress, Dr. Francis N. Stein’s garlycanthropes have proved themselves the ‘must have commodity’ of the season for monsters hunters everywhere. Their ability to detect undead and shapechangers has saved many potential victims from the jaws of a mimic, or from walking into a vampire’s lair.
  At your command, this inanimate bulb of garlic comes to life, sprouting little legs, eyes, and a panting muzzle for one hour, and gaining the stats and features in the associated statblock. It is extremely friendly to you and your friends, but is skittish if any of them are undead or shapechangers.
  In combat, the garlycanthrope shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take one of the actions in its stat block or the Dash, Disengage, Help, Hide, or Search action.
  Once you activate the garlycanthrope, you can’t do so again until you finish a long rest. Be careful not to eat it in the meantime!
