The Ring of Spirits is a niche item in Remnant 2: The Forgotten Kingdom that can be exceptionally useful when paired with specific Archetypes. It increases the user's Mod Generation for each of their active consumables, allowing you to significantly increase your Mod usage.
Remnant 2 How to get RING OF SPIRITS (Infested Abyss Secret Dungeon) | The Forgotten Kingdom DLC
You'll find the Ring of Spirits in the underpass of the Infested Abyss in Remnant 2: The Forgotten Kingdom DLC. To get there, approach the entrance to the area and go straight, following the left wall until you can drop off a ledge into a narrow passage leading into the underpass. Keep dropping down carefully until you reach a large chamber surrounded by pillars and a central corridor.
The Ring of Spirits is located in a secret passage that you can reach by lowering one of the pillars. You can do this alone, unlike the Pan War Band, which is located in the same area and requires two players to obtain. Here's what you need to do to get the Ring of Spirits:
One of the many new rings in The Forgotten Kingdom, the Ring of Spirits grants an additional three percent Mod Generation for each active consumable you have, up to a maximum of five consumables at a time, resulting in a total of 15 percent additional Mod Generation. This means that Alchemists can benefit greatly from the Ring of Spirits due to its increased consumable life, while Archons can achieve an even higher Mod Generation than they already have simply by using these consumables and reaching impressive levels of this key stat.
