It is hard to write a guide without spoiling the whole final before the STEPS????. Oh my god, with the new From Software game releasing later this year (Armored core) please, just write a generic description before the steps, and AFTER THE STEPS the full final. I love this site, but i'm disappointed with this specific page.

try finger
but hole

Got all 4 of the endings. That means 4 playthroughs. I'm happy. The Return ending is definitely the best as it shows Wolf alive, the Divine Child is pregnant with Kuro from the way she dresses and how she walked ('cradle' literally means a baby's bed after all) and they are about to embark on the journey west to return the Dragon's Heritage to its home. The text and dialog further implied that returning the Dragon's Heritage does not mean Kuro dies at the end so it's quite likely he'll be born normal. As for Wolf, he'll still remain undying throughout the journey enabling him to protect both his charges until the Dragon's Heritage is returned and his immortality is presumably ended. Other than the above, why this is best ending? Sequel hook!

The Purification Ending is arguably the best outcome. Sekiro’s purpose is to protect Kuro no matter the cost, meaning that it will eventually result in his own demise. In any other outcome, Kuro is either killed or consumed and therefore ceases to exist. If you want to do Sekiro’s character justice, go for the purification ending.

I got the "Do what needs to be done" line from Kuro but Emma isn't moving to the top of the stairs. Is that ok or should i just go get the shelter stone?

(For the person below me) It's considered the best one because even if Sekiro sacrifices himself to sever Kuro's immortality, someone else might be chosen by the Divine Dragon to become the next Divine Heir like Kuro was as Sekiro never killed the Divine Dragon, only took it's blood/tears. In the Return Ending, Sekiro and the Divine Child leave Japan with the essence of Kuro to return the Dragon to it's original location somewhere west meaning all this fighting and greed for eternal life for Divine Heritage will finally leave Japan upon achieving the Return Ending, in a way serving the greater good for the people of Japan, hence why it is considered the "best" ending

How is Dragon's Homecoming ending the good one? Kuro still dies, well technically the Divine Child eats him, but still he is not alive.
Imo the good ending is the one where Sekiro sacrifices himself for Kuro to live.
And the default ending where Sekiro becomes the Sculptor is the more poetic one.
Dragon's Homecoming is just meh.

Im trying to do the return ending but the door to the inner sanctum wont open when i've got the snake visera. Have i done something wrong?
