Resonance: A Plague Tale Legacy – How to Cross the Chapter 4 Spike Traps

The spike traps in Chapter 4, “From Hell It Rose,” are the first puzzles in Resonance: A Plague Tale Legacy that can kill Sophia instantly. Step on the wrong floor tile and spikes shoot up; pick the wrong wall socket and you get skewered. The whole sequence hangs on one tool you unlock earlier in the chapter, the Sphere’s Light Reveal ability, which exposes hidden symbols and glowing paths only while you stand in light.

Quick answer: For the corridor, walk the far-left tiles straight across the first trap, then start far-right on the second trap and go forward two tiles, left one, forward one. At the spike wall, insert the Sphere into the socket marked with the scales symbol on the left. In the large room, boost Leni to the lens and follow the blue floor line one segment at a time.

How Light Reveal decides the safe tiles

Hold R1 (RB) while standing in a light source to make the Sphere reflect light and expose the hidden markings. When you reach the first trap, this shows four symbols on the walls to your left and right. Those four are your “safe” symbols. Any floor tile stamped with one of them is safe to stand on; everything else triggers the spikes.

Sophia copies the four symbols into her book automatically, so you don’t have to memorize them perfectly. The important limit is that Light Reveal only works while you are lit. Once you step onto the trap tiles you lose the light, so read the path first, then move by memory.

Spike trap corridor: the three safe routes

The corridor has two floor traps followed by a set of spiked walls. Check the wall symbols with Light Reveal before each one, then follow the routes below.

At the first floor trap, move to the tiles hugging the far-left wall and walk in a straight line across. These are marked with the circle-on-a-stick symbol, and following them takes you across untouched.

At the second floor trap, start on the far-right tiles. Walk forward two tiles, turn and move one tile left, then step forward one tile to reach the exit. This zigzag keeps you on the panels shown in Sophia’s book.

At the spiked walls, do not insert the Sphere randomly, since a wrong socket is an instant kill. Six symbols sit above six holes, and only the scales symbol matches your safe set. Use Light Reveal to find it, then place the Sphere in that socket on the left side to shut off the spikes and open the way through.

Note: The scales socket is the safe one, sitting among the holes on the left. If you are in a rush, aim for the scales symbol rather than counting holes, since the symbol is the reliable marker.

Trap	Safe route
First floor trap	Far-left tiles, straight across
Second floor trap	Far-right start, forward two, left one, forward one
Spiked walls	Sphere into the scales-symbol socket on the left

The large spike-trap room with Leni

The next room is a full floor of spike traps with a single manual light source. You cannot brute-force this one, because Leni has to aim the lens at you so you can use Light Reveal on the move.

Follow the platform around to the left of the room and drop down beneath the lens. Boost Leni up to it when prompted so she can shine the beam onto Sophia.

Move carefully to the ground beneath the entrance without stepping on the trap tiles. Activate Light Reveal and look for the blue-green line, which begins near the tile where the trail starts.

Walk forward only on tiles the blue line crosses. Stone tablets hanging from the walls will block Leni’s light at several points and cut off Light Reveal. When that happens, memorize the next few tiles, step back if needed, and re-read the line once the light returns. Repeat until you reach the far side.

At the end, clear the wooden blockade to help Leni across, then open the door to continue. Watch the exit passage too, since a ceiling spike trap drops down as you pass through, so sprint straight across it.

How to know you cleared it

You have solved the corridor when the spiked walls retract after the Sphere locks into the scales socket, letting you walk through unharmed. You have finished the large room once Leni rejoins you and the door past the ceiling spikes opens. If you keep dying, the cause is almost always the same: you either stepped on a tile without a safe symbol, or you moved while out of the light and lost track of the path. Reset to the last lit tile, re-check the symbols with Light Reveal, and advance one confirmed tile at a time.
