Endings
There are four endings. The first two turn on a Relicta choice after the Aurifer. Endings 3 and 4 are hidden achievements, and no method for them is known.
Spare every Relicta and the last fight is Lacuna, ending in SOLVE ET COAGULA.
Kill one Relicta and the last fight is Hermes, ending in MAGNUM OPUS.
| Ending | Steam line | Hidden | Unlock |
|---|---|---|---|
| SOLVE ET COAGULA | Get Ending #1 | Listed | 2.8% |
| MAGNUM OPUS | Get Ending #2 | Listed | 2.4% |
| VIVUS EX MORTIBUS | Get Ending #3 | Hidden | 0.4% |
| RENUNTIATIO | Get Ending #4 | Hidden | 1.2% |
Four names on Steam
SOLVE ET COAGULA is the achievement for ending 1. It is listed, and the global unlock rate is 2.8%. MAGNUM OPUS is ending 2, also listed, at 2.4%. VIVUS EX MORTIBUS is ending 3, hidden, at 0.4%. RENUNTIATIO is ending 4, hidden, at 1.2%. Each description is only “Get Ending” plus the number. The Latin titles are the achievement names.
You play Julia, and Clara Kovacic performs her. The name Julia does not appear in the achievement descriptions. The sparing route is the one described as the good ending. The killing route is the one described as the bad ending.
What the choice changes
The split happens after the Aurifer. One branch is spare every Relicta, then Lacuna as the last fight, then SOLVE ET COAGULA. The other is kill one Relicta, then Hermes as the last fight, then MAGNUM OPUS. The buttons above only switch that pair. Endings 3 and 4 stay hidden because no method is known.
Lacuna and Hermes also have their own achievements outside the ending names. Acrophobia is die by being dropped by Lacuna. Devoured is get eaten by Hermes. Those are deaths, not the ending unlocks. The Lacuna, Hermes, and Relicta entries collect the achievement lines that mention them.
If you are choosing a route for ending 1 or ending 2, use the spare or kill switch, then open the puzzle index at the Desiderium finale. That heading is the last puzzle in the order. Follow the walkthrough when you need the solution steps.
Rates and the two deaths that are not endings
Ending achievements are a small slice of the 24. Ending 1, SOLVE ET COAGULA, is at 2.8%. Ending 2, MAGNUM OPUS, is at 2.4%. Ending 3, VIVUS EX MORTIBUS, is hidden and is at 0.4%. Ending 4, RENUNTIATIO, is hidden and is at 1.2%. Each of those four descriptions is only the phrase for getting that ending number. The Latin titles are names, not a second sentence of instructions.
Two nearby achievements look like ending conditions and are not. Acrophobia is dying because Lacuna drops you, at 0.9%, and it is hidden. Devoured is being eaten by Hermes, at 2.6%, and it is also hidden. Both are fail states with their own achievement entries. Relicta is the creature the spare-or-kill choice is about. The choice comes after the Aurifer. Julia is the player character, and that name is absent from the achievement descriptions.
If you are checking ending 1, spare every Relicta, expect Lacuna as the last fight, and look for SOLVE ET COAGULA. If you are checking ending 2, kill one Relicta, expect Hermes as the last fight, and look for MAGNUM OPUS. The Desiderium finale is the last puzzle heading. Open it for the final puzzle, and open Lacuna, Hermes, and Relicta when you need each creature’s achievement line. Endings 3 and 4 remain names plus hidden flags until a method is known.
Global percents move as more people finish, so they are not a fixed ranking. If you sort achievements by rarest first, VIVUS EX MORTIBUS at 0.4% and RENUNTIATIO at 1.2% land among the harder rows, next to Wrench Queen at 0.2% and Heart of Lead at 0.3%. SOLVE ET COAGULA and MAGNUM OPUS sit higher, at 2.8% and 2.4%, with the listed endings rather than the hidden pair. Open the achievement entry for the icon before you treat a Latin title as a puzzle clue.
Julia is bringing an old apartment key back to a film-maker ex. The Relicta choice is not in that apartment. It waits until after the Aurifer, in Desiderium. Spare every ghost and Lacuna closes the route. Kill one and Hermes closes it. De Relictis, reading every page of the old book, is a listed achievement at 4.1% and is not an ending. Heart of Lead asks you to kill every Relicta ghost and does not, by itself, name ending 3 or ending 4.
