Use in the shooting phase instead of firing a weapon. Nominate a direction from the Librarian and draw a line 3D6" long in that direction. You cannot choose a line that might pass through a unit in close combat. Any model (friend or foe) which the line crosses over takes a Strength 5 hit; normal saving throws allowed. A unit suffering any casualties from this attack must take an immediate Morale check or fall back. If the unit passes, but loses 25% or more of its models in that Shoot phase, it must still take the Morale check for casualties as normal.
