Codex System ​

The Codex System is a core progression mechanic in Vega Realms that enhances your build with powerful abilities.

Each Codex is tied to a specific playstyle or specialization, allowing players to customize how they fight and evolve over time.

What is a Codex ​

A Codex acts as a combat enhancement system, providing:

  • Unique abilities
  • Build customization through Bolt-Ons
  • Progressive scaling through experience

👉 Unlike traditional skill systems, the Codex adds a layer of active abilities on top of your build.

How It Works ​

Each Codex follows the same structure:

  • 3 Core Abilities → shared with all build variants 1
  • 2 Bolt-On Slots → customizable abilities

👉 You can equip only 2 Bolt-On abilities at a time, even if you unlock more.

Sparks System ​

All Codex abilities are powered by Sparks.

Sparks are generated through combat actions, depending on your build:

  • Dealing damage
  • Casting spells
  • Applying effects
  • Controlling enemies

👉 The more actively you play, the faster you generate Sparks.

Codex Progression ​

Codexes level up through combat.

  • Maximum level: 10
  • Each level grants: 3 points

👉 Total points available: 30

These points can be used to:

  • Increase damage or healing
  • Improve duration of abilities
  • Reduce cooldowns
  • Enhance scaling

Unlock Requirement ​

Each Codex begins gaining experience only when its main skill reaches 80.0.

Before that:

👉 The Codex remains at Level 0 with base effects only.

Bolt-On System ​

Bolt-On abilities are unlocked based on specific skills.

  • Unlock thresholds: 90.0 and 100.0
  • Different builds unlock different Bolt-Ons
  • Bolt-Ons define your specialization and playstyle

👉 This allows hybrid builds and deep customization.

Design Philosophy ​

The Codex System is designed to:

  • Encourage build identity
  • Promote experimentation
  • Reward active gameplay

👉 Your Codex does not define your build — it enhances it.

Important Information ​

  • Only 2 Bolt-On abilities can be active at once
  • Core abilities are always active
  • Codex progression is tied to combat, not passive gain
  • Stronger builds benefit more from Codex scaling
  • Hybrid builds can mix Bolt-Ons from multiple skill paths

Notes ​

1 For example, the Mage, Summoner and Necromancer will share the same 3 abilites of Codex of Arcana. But they can choose the last two abilities as Bolt-On based on their variant.
