Entangle

This spell causes tall grass, weeds, and other plants to wrap around creatures in the area of effect or those that enter the area. Creatures that fail their Reflex save gain the entangled condition. Creatures that succeed at their save can move as normal, but those that remain in the area must save again each round. Creatures that move into the area must save immediately. Entangled creatures can break free by making a combat maneuver check, Athletics check, or Mobility check against the DC of this spell every round. The entire area of effect is considered difficult terrain while the effect lasts.
