This spell causes grasses, weeds, bushes, and even trees to grow thorns and wrap and twist around creatures in or entering the area. The spell's area becomes difficult terrain and creatures move at half speed within the affected area. Any creature moving through the area or that stays within it takes 6 points of piercing damage.

A creature with Freedom of Movement or the woodland stride ability is unaffected by this spell.
