You seem to be stuck in a nasty patch of thorns sprawling all about the
trees in this part of the forest.  The six-inch barbs effortlessly catch in
and pierce through your armor, boots, leggings, sleeves, and other
equipment.  As you struggle to free yourself from the prickly things, you
fervently hope that no one comes along and spots you in here.  
A thorny, red-veined vine twines its way around your feet.
