I was reading through this question and basically any answer can be undone by most if not all of these things:
- the Wish spell
- the Fates card from the Deck of Many Things
- a cleric's Divine Intervention
So I was wondering, is there any effect in official D&D 5e material that can actually not be undone by any of the methods listed above or in any other way? Unearthed Arcana and such included; no homebrew.
The effect doesn't have to be death. It can be an effect with a non-permanent duration, like an Antimagic Field - though Antimagic Field could be undone by any of the above, so it's not exactly an example of what I'm looking for.
