Pheromone trail

Lictors release a trail of potent pheromones that guide fresh waves of bioforms to the slaughter.
Use this Stratagem when a TYRANIDS
INFANTRY unit from your army is set up
on the battlefield as reinforcements if there is
already a LICTOR from your army on the
battlefield. You can set up the unit wholly within
6" of the LICTOR and more than 9" from any
enemy models, rather than following the normal
rules for setting up the unit.
