Vertas pass control point locked rooms

At least one of the chests in vertas pass is possible to loot even when the room is "locked" by the control point. If you stand at the door, open it, and open the chest before the door closes, you get the full loot. You do not need to enter the room (and will be teleported away if you do). This gives easy access to the reward loot which is only meant to be accessible by defeating a wave at the control point.
