This is the solution for the 'repair Faeyan DND player' quest. Although this is not a very hard quest, the translation from russian to english of this quest is quite poor. It took me quite a while just to figure out what the hell the Faeyans even were asking me to do.
The point of the quest is to tune a DND player. This is done by checking two squares on a 3x3 square board. Each square can be either black or white. The manual for the DND player says that there are two possible tune options, either a 3x1 line or a 2x2 square of black. Your task is to check two squares and eliminate one of those two options.
The solution to this puzzle is:
Check box 2 and 8.
This seems kind of weird to me, because if the square was 4,5,7,8 picking 2 and 8 wouldn't reveal that. This is the solution that worked for me however, so if you don't get it the first time keep on trying with the same two boxes.Solution to Repair the DND player quest,
