The Spike Trap Puzzles in Resonance: A Plague Tale Legacy test your ability to read the environment and use Sophia's Sphere Key. Some traps require you to match symbols, while others use the Sphere Key to reveal a safe route through the room. There are three main sections to get through, with the first section containing two similar platforms. Here's how to solve every Spike Trap puzzle in Resonance: A Plague Tale Legacy.

Spike Trap Puzzles 1 and 2: Match the Symbols

The first two platforms work almost identically. Each one has a metal floor divided into nine squares, but stepping on the wrong square triggers a deadly spike trap.

Resonance: A Plague Tale Legacy (RaPTL) doesn't immediately show you which squares are safe. Instead, you need to use the Sphere Key to reveal the clues.

How to Cross the First Platform

  1. Before reaching the platform, stand in the area where the sunlight hits the ground.
  2. Pull out the Sphere Key.
  3. Use its reflection to reveal the symbols on the platform.
  4. Look at the symbols displayed on the nearby walls.
  5. Match the symbols on the platform with their corresponding symbols on the walls.
  6. For this platform, follow the left side.
  7. Look for the symbol with a cross and a circle in the middle. It appears on the left column.
  8. Step only on the matching squares and continue to the other side.

Once you reach the end, you'll find another platform that uses the same symbol-matching mechanic.

How to Cross the Second Platform

You can solve the second platform in the same way, but its safe route is different. After using the Sphere Key to reveal the symbols, follow this path:

  1. First row: Use the far-right square.
  2. Second row: Stay on the far-right square.
  3. Third row: Move to the middle square.
  4. Continue forward to safely cross the platform.

You don't need to memorize the symbols from the first platform. The important thing is to use the Sphere Key and match the symbols before moving.

Tip: Don't rush across these platforms. One incorrect step is enough to trigger the spikes, so check the symbols before committing to a square.

Spike Trap Puzzle 3: Stop the Moving Spikes

The next section changes the mechanic. Instead of crossing a platform, you'll need to get past a spike trap that continuously opens and closes.

Six Sphere Key sockets surround the area, but the correct one isn't immediately obvious.

How to Stop the Spike Trap

  1. Look around the room and locate the six Sphere Key sockets.
  2. Pull out the Sphere Key to reveal the symbols associated with the sockets.
  3. Open Sophia's Journal.
  4. Check the extra symbols she recorded during the earlier Maze Symbol Puzzle.
  5. Compare those symbols with the ones revealed around the sockets.
  6. Look for the symbol resembling an old weighing scale, with two triangles and a plus-shaped symbol above them.
  7. Find the socket displaying this symbol.
  8. Place the Sphere Key into the matching socket.
  9. The moving spikes will stop.
  10. Walk through the opening before continuing into the next area.

This section is a good example of why you should pay attention to the symbols Sophia records in her Journal. Some of them aren't immediately useful, but they become important in later puzzles.

Spike Trap Puzzle 4: Follow the Glowing Trail

The final section takes place in a much larger room with a huge metal platform covering part of the floor. Unlike the previous sections, you don't need to match symbols or find a specific socket here.

Instead, you need to use a reflector to make the Sphere Key reveal the safe path.

How to Cross the Final Spike Trap

  1. Find the reflector sitting on the raised platform.
  2. Climb the rubble beside the platform.
  3. Give Leni a boost so she can reach the reflector.
  4. Have Leni move the reflector into position.
  5. Pull out the Sphere Key.
  6. Let the reflector direct the light onto the large metal platform.
  7. Look for the glowing trail that appears across the platform.
  8. Follow the trail carefully from one side to the other.
  9. Stay on the illuminated route to avoid the spikes.
  10. Once you reach the opposite side, look for the wooden plank blockade.
  11. Break the planks to open the way for Leni.
  12. Continue forward to leave the spike trap section.

The key to getting through these traps is to use the Sphere Key whenever the path isn't obvious. It reveals hidden symbols and trails that point you toward the correct solution, while Sophia's Journal provides useful clues for some of the more obscure symbols.
