In Kid Icarus: Uprising for the Nintendo 3DS, you can find twelve Zodiac Chambers hidden throughout the game. Inside of the Zodiac Chambers, you’ll find a total of nine Zodiac Weapons.
Here are the nine Zodiac Weapons you can find, and where to find them.
Aquarius Blade – In Chapter 23, after grinding the first rail, get back on and ride it the way you came and it will take you to the chamber.
Cancer Claws – In Chapter 8, in the Constellation Room, jump up to the first platform and walk counterclockwise all the way around and fall back down behind a group of stars where you’ll find a door leading to a portal to the chamber.
Capricorn Club – In Chapter 20, look for the jail cells in the castle. Inside of the cells you’ll find a switch on the ground which will open another cell. Inside of the cell, you’ll find a hidden passageway to another cell that leads to the chamber.
Gemini Orbitars – In Chapter 6, defeat Dark Pit in the underground temple, then check the corners of the temple for the entrance to the chamber.
Leo Cannon – In Chapter 10, look for the room with the first Guttler. In the next room, follow the left wall to find the chamber.
Sagittarius Bow – In Chapter 2, in the hallway before you meet Magnus, look behind a tapestry there for the entrance to the chamber.
Scorpio Staff – In Chapter 16, once you find the Aether ring, continue through the level and look for a hole in the ground. As you’re falling, keep rotating your view until you see the portal to the chamber.
Taurus Arm – In Chapter 4, look for the room with two swinging blades. Fall into the pit and you will find a glowing hole near a trapped Clubberskull. Fall down the hole and look for the entry to the chamber behind you.
Virgo Palm – In Chapter 12, head to your right to find a hidden elevator after fighting the Nutski. The portal to the chamber is at the bottom.
