Okay so I beleive I got the two endings... basic ritual of dusk that seems to be not good. And the one I believe is true where there are two pictures: Elsbeth in common clothes and Elsbeth in Landskneht clothes. That seems to be the true one. Thought it is interacted with flame and you marked flame as different ending. So IDK. Third one needs interaction with sword that seems like kinda boring stuff to do. And what is fourth ending?
P.S. Thanks for all advices!
Yup, you got Age of Dusk ending and true ending, third one is that Esbeth gets out of dungeon but "darkness may come back" (it's sane picture as Esbeth in common clothes) and the easiest one is just at the start of the game go to the exit of dungeon while not finding idol and just running away.
There is one with sword and I found another one in game files named marriage. I dunno how to get both of them tho.
