Arcane Vassal

A Slann Mage-Priest can choose to cast any magic missile or direct damage spell through an Arcane Vassal within 24" of him. If he does so, measure the spell's range from the Arcane Vassal and use that model's forward arc and line of sight for the purposes of casting the spell. If using an Arcane Vassal, a Slann Mage-Priest can cast magic missiles, even if his own unit is engaged in close combat (provided that the Arcane Vassal's is not). If a spell cast through an Arcane Vassal is miscast, the result of the miscast is applied to the Slann Mage-Priest, but the Arcane Vassal suffers a S 3 hit.
