Tenebris Somnia has four numbered ending achievements. Endings 1 and 2 split after the Aurifer is complete; the two hidden endings become available on a fresh run after both have been recorded.

SOLVE ET COAGULA

Spare every mercurial Relicta after obtaining the Aurifer, then finish the theater route.

Keep a save before the Relicta corridor so the same completed route can also produce Ending 2.

MAGNUM OPUS

Kill at least one mercurial Relicta with the Aurifer, then finish the alternate theater route.

A kill remains recorded for that run; reload the earlier save for the non-killing branch.

VIVUS EX MORTIBUS

After Endings 1 and 2, start a fresh game, use the Bible to win three optional challenges and place the three Iron Crosses on the third floor.

The Bible interactions occur before nearby ordinary puzzle solutions, so save before each one.

RENUNTIATIO

After Endings 1 and 2, start a fresh game and use the Apartment Key on the lobby entrance before taking the elevator.

This is the shortest ending and does not require replaying the building.

Ending 3 · Bible and three Iron Crosses

The Bible appears on the lobby table in the unlocked fresh run. Complete these interactions before solving the nearby ordinary puzzle.

  1. Second-floor apartment: use the Bible in the living room. Start from the Mars symbol and follow the diagram for six laps; defeat the enemies for the first Iron Cross.
  2. First-floor projector lock: use the Bible before opening it normally, enter 6666 and win the fight for the second Iron Cross.
  3. Cinematography room: use the Bible, connect the yellow RCA cable to the camera and change channels until the encounter begins. Win for the third Iron Cross.
  4. Third floor: enter the blue door left of the elevator, place all three Iron Crosses in the wall and follow the newly opened route.

For the six-lap direction, follow the arrows shown in the in-game diagram.

Fastest save plan

Keep one save immediately before the late Relicta corridor. Finish the no-kill route, reload, kill a Relicta and finish the second route. After both ending achievements register, begin a fresh game for Endings 3 or 4.
