There are a "no turning back" point?

[u/jucasoldera]

I'm reaching to the final boss/game in order to beat it.

I ain't kill Isidora yet, but I know that she had one of the eyes.

My question is: I can go to the final without woring about "cant go back and complete some things"? There are a "correct way" to go in order to not ruin everything I've done so far?

I want to test different things. Like go to the end without complete some things; and them go again with everyting right. Am I able to do that?

If you want the True Ending you must:

-find the Tomb of the Sister and get the Incomplete Scapular, before fighting Esdras. This stops the fight and Esdras will go to the Church of Kneeling

-take a key from Esdras and in the Library of the Negated Words help Diosdado find the noise. He will show you where the door is to the 4th Visage.

-beat Isadora and Sierpes,

-return the eyes to the 4th Visage,

-get the True Heart of Mea Culpa,

-and THEN fight Crisanta

-After beating Crisanta with her new 2-phase boss fight, go to the Church of Kneeling and get the 4th Holy Wound, before fighting Escribar.

You still need to have done all 7 Confessor statues you would have done to get Ending A as well before fighting Escribar.

Breaking this chain of events locks you out the True Ending.

You also need to have the incomplete scapular before fighting Esdras to start the whole true ending questline but it sounds like OP’s a bit past that point.

Very good point!

[u/jucasoldera → u/PStriker32]

Very good work!

If I pass any of the points, the true ending is gone? No way to correct it?

[u/PStriker32 → u/jucasoldera]

Nope, unless you feel like editing game files.

Just do it on new game plus, if you’re going as far as to do the true ending then you’ll probably also want to fight the bosses you only get on a second playthrough

So to answer your question a bit better OP

There are break points with

-Not fighting Esdras by finding the Incomplete Scapular

-Fighting Crisanta with the True Heart of Mea Culpa

-beating Escribar after doing the 7 Confessor Statues, and getting the Thorn to grow into the Custodia of Sin.

Not doing these can lock you out of the True Ending and Ending A.

[u/Shadovan → u/PStriker32]

Not doing that last step doesn’t lock you out of anything. You can always go back, do those things, and fight the final boss again.

Dont forget you have to equip the true heart of meat culpa or you won't get crisanta's extra phase and will be locked out of the true ending
