Recipe System

Karsus Codex uses two types of recipes to customize your items: full-item recipes pulled from vanilla BG3, and atomic recipes that let you build effects from scratch.

Full-Item Recipes

236 available

These recipes are reverse-engineered from iconic BG3 items. Apply "Phalar Aluve" to get that sword's unique singing blade effect, or "Luminous Armor" for its radiant damage aura.

Categories:

Acid Bludgeoning Charges Cold Damage Elemental Enchantment Finesse Fire Force Lightning Magical Necrotic On-hit Physical Piercing Poison Psychic Radiant Rare Simple Slashing Status Synergy Thrown Thunder Utility Weird

Full recipes bundle multiple effects together, just like the original items.

Atomic Recipes

19 effect types + 0 vanilla passives

Building blocks for fine-tuned item creation. Add exactly the damage types, stat bonuses, or special effects you want. Mix and match to create something unique.

Includes:

Extra Damage Stat Bonuses AC Modifiers Vanilla Passives

Vanilla passives include effects like Arcane Acuity, Cat's Grace, and Burning Fury.

How recipes work together

When you create a mod, you pick a base item (like a longsword or ring) and then apply recipes to it. You can combine full-item recipes with atomic recipes for maximum flexibility.

Example 1

Longsword + Fire Damage recipe

Example 2

Ring + Arcane Acuity passive

Example 3

Armor + Luminous recipe + extra AC

Growing library

We're continuously adding new recipes as we test them in-game. Currently at 236 full-item recipes and 19 atomic effects. Check the changelog on the home page for the latest additions.
