A354: Entangle both secures the target to the ground by description (the weeds and plants are attached to the ground, and are now wrapped around the target) and by text implication (targets "end their movement" and may "break free" with a Str or Escape Artist check after a failed save, and may "move normally" on a successful save).

An example of an Entangled effect that does not necessarily anchor the target is the effect of a successful Net toss.
