I saw this on fritz40k:
Vect with his Dias, nightshield and flickerfield
His bodyguard, Harlequins, but more importantly a Shadowseer.
Does this mean to shoot at the Dias, you are under the 2d6x2(-6) penalty?
It seems fishy to me, but there is no rule 1.) Stating models who can't pick transports by themselves can't accompany Vect, 2.) Veil of Tears says "any unit she[The Shadowseer] is with".
All this clocks in at 650 points for a 13AV Ravager with 5+ save that can be shot at a maximum of 18 inches.
