Scientific Data

Exploration Stage: Lamplighter's Workshop
From: Carlos Light
Description: You see, I don't only clean the lamps, I also do some research. I'm trying to find out how to replace the crystals. Their stock is stolen, and the remaining crystals in the lamps are gradually dying out. In the observation diary, I wrote that yesterday I investigated some kind of radiation. Let's look for the device I used.
Completed: You're a genius! I used the Polariscope to study the properties of a certain light source. I'll check the testimonies now, they might be imortant.
