the other combo with this is marcus' howl, which is one of his best and most overlooked abilities imo, since shikome can attack agaisnt your Df OR Wp this is a free 8" willpower drop, you also can add the winged nightmares trigger for an additional -2Wp and crush the crap out of whatever you want.
this combo gets really crazy when you have a lawyer force a living model to take a Morale test at a potential -8 then have the cerebus thats linked to the shikome use smell fear and jump that sucker.
so good....
