I thought we did just a couple of days ago. The Crucible is negating all energy:  DE, ME, SE, magic, everything. Even LE, once depleted, isn't replenished. The influence of the heavens and hells is cut off. Thenlines between dimensions and planes are blurring. The entire slate is being wiped clean.

You can physically fight all day long. Throwing a punch won't make a difference. But try and toss a fireball, nothing is going to happen. Use an attack that depletes your own LE, it's not returning. Lucida is the exception to that rule; whatever phenomena that is keeping her alive is able to create a field that allows for that exception. Ibrahim can siphon from her to use magic, Praetor can siphon from her to use pyromancy, and so on. But she can't be tapped by everybody all at once.
