The Sica blade sits behind a sealed tomb in Chapter 6 of Resonance: A Plague Tale Legacy, hidden just off the critical path during the “The Architect” sub-chapter. The door carries an axe sigil, and it only opens once you refract the Sphere’s three colored beams onto three matching gems. The catch is that you have to stand in one exact spot, because only that pillar lines up every beam correctly.
Quick answer: After you get Daedalus’s Key, take the small left-hand opening in the tunnel to reach the tomb room. Climb the near-left pillar with sunlight shining on it, then cast the Sphere’s tri-colored light so green hits the gem below the bull pillar, blue hits the gem below your pillar, and red bounces off the mirror into the gem at the back right. All three gems lit opens the axe hatch.
Where to find the tomb in Chapter 6
The tomb is tied to the “The Architect” portion of Chapter 6, right after you collect Daedalus’s Key in the room with the model labyrinth. Use the key to open the door, then head into the tunnel that leads away from the area overlooking the maze.
As you move through that tunnel, watch the left wall for a small opening. It splits off from the main route and drops toward the tomb chamber, so take the left path instead of continuing up the stairs. Inside, you will see a bull pillar in the center and several stone pillars with shafts of light shining down on them.
How to align the Sphere’s three beams
Only one pillar gives you a clean angle to every gem. Climb onto the first lit platform on the left side of the room, the near-left pillar with sunlight coming down on it. From there, pull out the Sphere and cast the three colored rays.
Set the green beam first, since it points at the most obvious gem. Then rotate the blue and red beams into place. The red ray is the tricky one, because it has to bounce off a reflecting plate in the room before it reaches its gem, rather than travel there directly.
| Beam | Target gem |
|---|---|
| Green | Gem below the bull pillar |
| Blue | Gem below the pillar you are standing on |
| Red | Gem at the back right, reached by reflecting off the mirror |
Note: several extra gems are scattered around the room as red herrings, and there are other platforms you could stand on. Ignore them. Standing anywhere other than the near-left lit pillar will leave at least one beam unable to reach its gem.
Solving the puzzle
Confirming it worked and claiming the Sica
Once all three red, blue, and green gems are lit at the same time, the hatch door with the axe sigil slides open. That is your confirmation that the alignment is correct. If the door stays shut, one beam is missing its gem, usually the red one failing to catch the mirror, so nudge the rays until every gem glows together.
Head down into the crypt and open the chest to receive the Sica. Its technique, Focus Rush, increases the Focus Gauge whenever you kill an enemy with the blade. There is also a single Resonance Point tucked just to the left of the chest, so grab it before you climb back out to the main path.
