How to use Abyss Cores in Crimson Desert
Crimson Desert features Abyss Cores, which are equipment mods for weapons and armor that require specific vendors called Witches to install. Players can find Witches by progressing through the main campaign to Chapter 5, with the first one, Elowen, located in The Witchwoods. Installing and removing these cores is free, but creating new sockets for them incurs a cost.
