Had this come up in a game against ogres the other day. Had terrorgheist infront of a unit of ogres (3 models) ironblaster just behind (very close) . Now I wanted to scream at the ironblaster but due to the terrorgheists head being positioned low my oponent said I could not scream as I could not draw line of sight from the TG's eyes to the iron blaster. Is this correct? In the end screamed at the ogres and caused only 1 wound got charged and no more TG (glass hammer or what)
