Once you get the Veil Sight and Mire power, progress until you are able to play 
the Farm mission. If you have already completed the mission, select "Replay 
Mission" from the journal page. Go through the farm and underground base until 
you get to the room that contains the Shield power crystal. Once here, since you 
are in a room surrounded by crystals, when you activate a power you do not lose 
any Veil Energy. Simply place a rubberband around one of the Analog-sticks or 
any other method that keeps B.J. moving in the room, and leave the controller 
and console alone for the necessary amount of time to get the "Honorary Geist" 
and "Time Out" trophies.
