It doesn't make sense for the Cyclops to use Necromancy right now, and the Angel will probably appear by the third night.
Some Necromancy spells aren't displayed, and some are missing. So, I agree that Omega will serve as an indicator the next day. Although there are still exceptions. Mercury and the Angel. This is to say that you might not see death from poisoning, but the probability is low.

Mercury was probably defending, which also isn't displayed.
