Nau is a recruitable character in the game "Sword and Fairy: Fate of the Clouds." Players can increase her affection through completing quests and interacting with her. However, the ways to boost Nau's affection are scattered across various main and side quests. To prevent players from missing out, this guide on how to raise Nau's affection in "Sword and Fairy: Fate of the Clouds" is shared. By following the methods mentioned, players can easily increase Nau's affection to 100%.

After receiving information about the exotic golden scorpion from Liu Mayi, players will go to find it. Upon acquiring it, they will meet Nau for the first time. At this point, whether the player chooses to give the scorpion to Nau or trade with her, both options will increase her affection. However, note that giving it directly adds 20 points, while trading only adds 5. This 15-point difference can easily result in Nau's affection not reaching its maximum.

After giving the golden scorpion, follow Nau's instructions to reach Man Yin Forest. After the plot concludes, you can start the Thunderbolt Gate mission. Share the intelligence obtained (three times in total) with Nau, each time adding 5 affection points. If you share all three, an additional 5 points are added, making a total of 20. After completing the Thunderbolt Gate mission, Nau's affection increases by another 10.

From then on, just follow the main storyline. After completing all related main quests involving the Southern Border's Longevity Hall, Nau's affection can be maxed out at 100. There are five opportunities to increase Nau's affection throughout this main quest, which will automatically add up as the story progresses. These can all be obtained by following the normal procedure, without any additional conditions. After the final battle at the Longevity Hall, Nau will officially join the party.

The above is the method provided by the "Sword and Fairy: Fate of the Clouds" Nau affection guide. After completing all the steps mentioned, Nau's affection towards the protagonist can be maximized, and she will join the team after the final battle at the Longevity Hall. Go ahead and give it a try!
