Entangle

From Ardrana

By means of the entangle spell, the caster is able to cause plants in the area of effect to entangle creatures within the area. The grasses, weeds, bushes, and even trees wrap, twist, and entwine about the creatures, holding them fast for the duration of the spell. Any creature entering the area is subject to this effect.

Note: This spell originally appeared in this form in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
