I got my hands on Chaos Moliri walked right out after doing the trick

, teleported to Umpani base then back to Arnika, SURPRISE an auto ending said 'game over' assuming that the bomb have been tricked, so I reloded and decided that it could wait to later.
Now I found the Destinae Dominus, the bomb hasent been tricked yet, is it safe to keep it? or should it be one of the last thing I pick up? maybe I just could hide them somethere ontil later?
