Prerequisites: 5th-level contractor.

When the contractor projects her barrier, she can choose for magical vines to burst from the ground within it. This does not permanently damage the soil or floor—when her barrier is dismissed, the vines disappear and the ground repairs itself.

The contractor can select any number of creatures within her barrier when she creates this effect. Those creatures must make Reflex saves or become entangled by thorny vines, as the spell. They remain entangled until they break free or the barrier is dismissed, whichever comes first. Creatures that enter the area after the barrier is projected do not risk becoming entangled, but the entire barrier is considered difficult terrain while the effect lasts.
