When joined to a unit of Temple Guard, a Slann is always placed within the second rank. See Different Sized Bases within Units for further details of how to handle this. A Slann placed in the second rank may still act as normal (he may cast spells, use magic items, act as a general, army banner bearer etc). The Slann Magwe-Priest's palanquin allows it to float up to cast its powerful magic before dropping back within the protection of its unit. Because of this, the his line of sight is worked out as if the Mage-Priest himself was a large target. In addition, as long as the Slann has no enemy models in base-to-base contact, it may still cast magic missiles even if his unit is engaged in close combat. If the Slann joins any unit other than Temple Guard, it is placed in the front rank as normal.
