''You see an overaged Thorn Bush.''
This is a very large bush with sharp thorns. Cannot be harvested, and is mainly used as a primitive defense against invaders.
When a thorn bush reaches old age, the thorns will cause cutting [[wound]]s if you go on that tile - be wary of the orange "You are pierced by the sharp thorns!" message.
== Notes ==
* When a thorn bush reaches old age, the thorns will cause cutting [[wound]]s if you go on that tile - be wary of the orange "You are pierced by the sharp thorns!" message.
* 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 fog]] provides some protection to them.
