Treason of Tzeentch

The psyker reaches his thoughts into the minds of his victims, turning them upon their own allies.
Treason of Tzeentch has a warp charge value of 8.
If manifested, select an enemy CHARACTER
within 18" of the psyker and visible to him (not
the opponent's Warlord) and roll 2D6. If the

phase treat that character as if it were a model
from your army in your Shooting, Charge and
Fight phases.
