Etheric Spiral is a planetary material in Destiny 2 that you can hand in to Vendors to get items, weapons, and mods. Like all planetary materials, you can only find it in one place.
For Etheric Spiral, you will need to visit the Tangled Shore, home of The Spider and the Crow. If you want to maximize how much you can collect, and how quickly, there are a couple of things you should know.
Your ghost can help
If you Masterwork your Ghost Shell you will be able to put a couple of useful mods on it that will help you. First, you can put on mods that will automatically detect a resource node or chests. You can only equip one at a time.
Resource nodes will be marked by a triangular icon, and you can pick various ranges with a different mod capacity cost. They go all the way up to 75 meters. Another useful tip is that this extends from your vision range, not your character model, so if you are looking through a sniper scope, it will extend the range.
The chests will be marked by a small chest shaped icon. These are actually a better source than the resource nodes, as they will yield two Etheric Spiral per chest, while nodes will give you one. You can put a mod on your Ghost the can give you extra resources, bringing it up to two, but this will only happen sometimes. There are also two Combo mods, that will show both chests and resources, but at lower ranges.
If you have a friend you are playing with, it’s a good idea to each use one of the mods at the longest range to make life easier.
Tangled Shore Bounties
Doing Tangled Shore Bounties for The Spider will also get you some Etheric Spiral when you complete them, along with some XP to level up your character, Season Pass, or Artifact.
Random Chests and World Chests
Chest from Public Events, powerful enemies, or mini-events that you can find in some map areas may also give you planetary resources. If you see a chest, open it. World Chests are more limited and are marked on the map by a cross with a dot in the middle. Opening them will get you resources, but the chest will disappear afterward.
