Players undertaking Amicia and Hugo's journey in Chapter 4 of A Plague Tale: Resonance will encounter their first symbol code puzzle when attempting to unlock the trial door. Successfully opening this door is crucial for progressing toward a treasure before the army arrives.
The puzzle requires the use of the orb's 'Light Reveal' function, a new ability introduced to help players discover hidden elements in the environment. To utilize this, the orb must first be placed on the central pedestal and upgraded.
Once the 'Light Reveal' function is active, players can hold the orb up to expose hidden paths. For this particular puzzle, a light blue path will appear on the ground, leading from each pedestal to a symbol on the wall. Following this path with the orb will reveal the correct symbol for that pedestal.
After finding the symbol, return to the corresponding pedestal and input it. This process must be repeated for all three pedestals. Upon entering the correct symbols in the right sequence, the trial door will open, allowing players to continue their path.
For those encountering difficulties, the correct symbol sequence from left to right is: Y shape, C shape, and an upward arrow shape.
