Page 143 of 1st Age, the Dimensional Walk Power. It says: "A number of models equal to the strength of the power..."
Does this mean you can also drag enemy models with you trough the dimensional portal?
If so, that could be awesome for Insekt Domain. Give "Holding Grasp" ability and teleport to your own guys away from his. What can I say, I've been a Dark Eldar player for years. I fight dirty. ;)
