1. Can Eldrad can use his divination even if he is deployed in a vehicle? I see no reason why not.
2. What limitations are on his psychic powers from inside a vehicle? I gather he can cast fortune on himself & anyunit he is attached to . Or guide on himself & any unit he is attached to, or even on the transport he is inside of. But as there are no firing ports on eldar vehicles he can't use his abilities thru the vehicle to affect other units that require a target or los. So Doom and Eldritch Storm are not usable at all, and others function with the as before noted limitations?
3. What limitations exist for Eldrad with divination? Can he reposition himself away from a unit he is attached to? Move a unit in or out of a transport?
