The Blood Lance

Select a visible enemy model within 12" and draw
a line between them and the psyker. Roll a D6
for each model the centre of the line passes over.
For each roll of 5+ that model's unit suffers
a mortal wound.
The Librarian conjures a mighty lance, infused with
his innermost rage. Hefting this empyric projectile, the Librarian hurls it with all of his psychokinetic might, sending it hurtling through the enemy ranks to maim
and impale.
