While harpoon is stuck target: 7 (2d6) piercing damage at start of each of its turns marcher can't make Mycelial Harpoon attacks vs. others and target and marcher can't move over 30' from each other. A creature including target can take its action to detach harpoon via DC 13 Str check. Or mycelial thread connecting marcher to harpoon can be attacked and destroyed (AC 12; hp 10; vulnerability to thunder; immunity to bludgeoning poison and psychic) dislodging harpoon into unoccupied space within 5 ft. of target and preventing marcher from using Recall Harpoon.

Recall Harpoon. Pulls on the mycelial threads connecting it to its harpoon returning the harpoon to its empty hand. If harpoon is stuck in a creature that creature must make DC 13 Str save or be pulled up to 15 ft. toward marcher.
