You can find multiple puzzles and riddles to solve while working your way through the many side quests in Once Human. A particular riddle is available to you as you work alongside Lowe during the Martial God’s Home quest.
The primary task for this quest is to express your respect to the Janitor. As you might expect, there’s a certain act you need to do while next to the Janitor, and if you don’t perform it for them, they’re going to ignore you. Unlike the quest you completed to unlock this one, where you had to give ore to a Deviation, this one requires a specific action. Unfortunately for players, Lowe doesn’t provide exact details on what this action is other than paying your respects in Once Human.
