Every time "You would be reduced to 0 Hit Points but not immediately killed", you use the reaction and the entity isn't in control [it can't take control if it's already in control].

I agree but both of those things would normally be spelled out. I also get the feeling that the reaction should have a longer cooldown before it can be used again rather than just a minute when I compare it to other similar abilities.

Still not seen an answer to this so posting here:
What is frequency on dark archives living vessel dedication reaction? Seems like it should be once a day or once an hour but there is nothing. Also it seems like you should get the wounded condition when using it, but that is not stated either.

There are a few monsters where this is not the case, where the natural armor from the template is added instead of replaced, hence why I am confused on it.

How do natural armor change when a creature is reanimated as a skeleton? Does it lose all the natural armor of the base creature or does it get to keep it and add an amount listed in the skeleton template?

As far as I can see there are examples of both happening for various monsters.
