Decorations

Unlocked a little later into Chapter 2 are Decorations. These will offer the most expansive options for your late-game builds. Just like your equipment, these come in two flavors: Weapon Decorations and Armor Decorations. Each one houses one or two skills, depending on their rarity. You’ll then be able to slot these into your equipment to add even more sources for skills.
A key thing to remember is that the equipment needs to have Decoration slots to use these. Don’t be surprised if you haven’t crafted any weapons or armor with Decoration slots by the time you unlock this mechanic.
