Primal magic awakens plants and vines to grasp at the caster's enemies. Entangled creatures suffer a 90% penalty to movement speed, a 50% attack speed penalty, and a -1 penalty to attack rolls, AC, and Reflex. A successful Reflex save negates this effect. Entangled creatures may leave the affected area to escape it's effects, or attempt to make a Strength check every 2 seconds to negate. Area of effect fire spells will destroy these vines and free any entangled creatures. Incorporeal creatures and oozes are naturally immune. Fire elementals and other fire creatures are immune because they burn through the plants.
