A thorn bush is a bush that, when touched, deals damage for several seconds in Grimm: Dark Legacy. After it has been touched once, the character may pick the thorn bush.
- Thorn bushes can be helpful with hunting, since they damage animals as well.
- Finding dead animals you never engaged is a strong hint there is a thorn bush or other dangerous plant nearby.
- To pick thorns, throw a rock at the base of the thorn bush to destroy it so you don't prick yourself.
