The Bloodless King's Vow is an incredible ring released in the Remnant 2: The Forgotten Kingdom DLC. It grants you Lifesteal with ranged weapons, which is ideal if you prefer to attack enemies from a safe distance. Here's how to find it.
Remnant 2 How to Get the Bloodless King's Vow and Crown in Goddess' Rest | The Forgotten Kingdom DLC
You can obtain the Bloodless King's Vow ring in Remnant 2 after defeating The Bloodless Heir boss in Goddess' Rest. Begin this fight in the altar area, which you can reach after interacting with the five statues of light surrounding the castle deep in the Goddess' Rest region and opening the main gate.
Once you've done this, interact with the offering plate at the altar and close the menu to start the boss fight. After defeating The Bloodless Heir, the Bloodless King's Vow will be added to your inventory. You can also go forward to find the Bloodless Crown, which can be found in front of the tomb behind the altar.
To reach the altar area, simply follow the main path in Goddess' Rest. After interacting with the first pillar, explore the area around the castle to find the other four. If you haven't unlocked the Goddess' Rest area yet, you can reach it via Luminous Vale by heading to the upper left path, which is accessible via an elevator on the ground floor.
