The Valor of the Soldier Helm and Breastplate can be found very close together in Immortals Fenyx Rising, and we all know that nothing is better than matching armor.
You can find both near the Observatory on Crashing Rocks, and you will have a chance to grab them both while trying to solve a particularly bothersome puzzle in the area. In this guide, we will focus on the Helm and Breastplate locations, but if you want help the with Observatory Constellation Puzzle be sure to check out that guide.
To get the Valor of the Soldier Helm, you will need to climb all the way to the top of the Observatory. Here, you will find a wall that you break in with your heavy attack. Go inside and you will find a pressure pad on the ground up a small set of steps. Stand on this and a brazier in front of you will light up. You can now shoot your guide arrow through the fire, out the other side, and into another brazier on the far side to light it.
When you set it alight, the red energy door in front of you will fade away, revealing a chest. Open this chest to get the Helm. The Helm will give you a bonus of 10 percent damage to Sword attacks, and after upgrading it enough you will get a +20 percent stamina gain from each hit with the sword.
To get the Valor of the Solider Breastplate, head back out through the hole in the wall and turn left. Climb across the rocks to the area with the brazier you hit the arrow and you will find another chest. This one contains the Breastplate, which will give you an extra Stamina chunk, and -10 percent Stamin consumption over time when it is upgrade enough.
