== Notes ==
* It seems that reaching old age is not enough for thorns to become effective. It doesn't start functioning at the start of old age, but after about a week of being old.
* Player with at least 40 [[faith]] in [[Fo]] will not be harmed by the thorns, and the Fo spell [[Morning Fogfog]] provides some protection to them.
* [[Enchanted tree|Enchanted]] thorn bushes do not hurt either.
* Axes do 50% lower damage to these bushes than other bushes and trees.
