A thistleshrub is a large plant (MG 132) and plant elemental (LoM 60) found in Tanaris. These elementals protect the Thistleshrub Valley - these are creatures of living vines, attacking anything that comes near. (LoM 58) Thistleshrubs immobilize any moving foe with roots, then move in and pound their prey to death. A thistleshrub always attacks the foe with the most fluid -- i.e, usually the largest one. They ignore constructs and creatures with no water content unless such creatures attack them first. (MG 132)
