The balbal can spend 1 minute using its razor-sharp tongue to carve a Small or Medium piece of wood into a humanoid shape. This dummy appears to casual inspection indistinguishable from the corpse of a humanoid of the same size (which may resemble a specific individual). Creatures carefully inspecting the corpse dummy can attempt a DC 15 Intelligence (Investigation) check to reveal the ruse. This is a magical illusion effect, and creatures using detect magic to examine the corpse dummy have advantage on this check.
