Remnant 2 features a wide selection of archetypes from which to choose--some of which you'll have to seek out in-game before you're able to equip them and use their abilities. One of these--the Ritualist--can only be obtained if you own The Awakened King DLC and get your hands on a specific item. Below, we'll tell you how to find the item you need and what to do with it so that you can unlock the Ritualist.
How to unlock the Ritualist archetype in Remnant 2
To access the Ritualist archetype, you'll need to get to the Forlon Coast in Losomn, which is an area added in The Awakened King DLC. As you explore this area, you should eventually stumble upon an area with a lot of floating boats with makeshift walkways between them.
Make your way across these boats and into a canal where you'll find a section of wall busted out. Through this passage is a short cave with an enemy at the end. Kill the foe, then examine the glowing item on the wooden pillar here. This will earn you the Ragged Poppet.
