I don't think it is working as intended and results in me being killed quite often by giving the enemy the advantage in PVE. Example. In Ulfheim I engage a bear and his archer master and a berserker. After applying chaotic poison to me weapon and inflicting all three opponents they proceed to teleport all over the place constantly. The archer keeps appearing off in the distance and a comfortable gap between us that I cant close because the confusion of the poison acts as a teleport for them all. As they start blinking all over the place their attacks still go off as though they were standing close to me. In the end there seems to be no negative effect other than the DoT. The confusion just teleports archers around giving them a gap closure benefit.
