The Thunder Helm
- Divine Beast Vah Naboris Main Quest completed
To start this quest, examine the Thunder Helm next to Riju and tell her you want it. Basically, this quest requires that you complete all the other Gerudo Town Side Quests (which are given by Gerudo), two of which do not become available until you start this quest first. The quests to complete are:
- Tools of the Trade Side Quest
- Medicinal Molduga Side Quest
- The Mystery Polluter
- The Search for Barta
Once you complete all four side quests, return to complete the quest and get the Thunder Helm.
The Thunder Helm has been passed down as a prized treasure of the Gerudo since Urbosa's time. It doesn't seem like they'll just give it to you, but if you're able to solve all the town's problems, they'll at least lend it to you.
You solved the problems of everyone in town!
Riju gave you the Gerudo's symbol of friendship, and you got the Thunder Helm!
