Sin Monk capstone ability question

[Natan Linggod 327]

So the capstone for the Sin Monk , I think that's the name, is that if they die and are brought back, they come back as a sinspawn and become an NPC.
(Kind of a crap capstone but anyway.)

Does that include coming back from things like reincarnate, which create a specific body for you?
Does the specific details of the capstone ability trump the specific details of the spell?

And what if someone wished them back or used miracle? Would the class ability trump those two uber spells?

What book is it from?

I tried a keyword search on Archivesofnethys and couldn't find anything.

Apparently its in the "Pathfinder Player Companion: Antihero’s Handbook".

Wow, what an awful capstone. Though immunity to mind-affecting effects is nice to have.

Specific class feature trumps spell, so he'll reincarnate as a sinspawn.

Wish or miracle would just be imitating a lower-level spell to bring him back from the dead, so he'd still be a sinspawn. However, those two spells should IMO be able to turn him from a (living) sinspawn back into his former form; we know they can do that for reincarnate, and the class feature doesn't specify he must remain a sinspawn forever.

If it had something like "Automatically reincarnates you as a sinspawn" then it would be a bit better. You wouldn't have to waste matts on a res AND a wish.
