What does the Codex of Power do?
The Codex of Power is a new system that rewards players with a Legendary Aspect after completing one of the game's over 120 Dungeons. A Legendary Aspect allows a player to upgrade a Rare or Legendary item with a specific Legendary affix. The system affects all of a player's characters.
Each Dungeon is associated with a Legendary Aspect reward that the player is shown beforehand in the Dungeon's description. Most of the Aspects are Class-based, meaning that players can strategically choose Dungeons with rewards that are relevant to their builds.

Imprinting an item with the Codex of Power
Unlike Aspects acquired and extracted from monster drops, which are one-time-use only, Codex of Power Aspects can be applied infinite times to Rares and Legendaries (assuming the player can afford the Occultist's Gold and Veiled Crystal fee).
Ensures weakest Legendary affix roll
While the Codex of Power system is convenient, there's a catch: the range of the Aspect's Legendary affix imprinted on an item will always be the lowest possible value  (e.g., for an affix range of 10-20%, 10% would always roll). This makes the Codex of Power Aspects weaker than those extracted from monster-dropped Aspects.
Only provides half of possible Legendary Aspects
Another drawback of the Codex of Power is that it only offers players access to half of the Legendary Aspects in the game. For the rest, players will have to acquire Legendary items from monster drops and take them to the Occultist to extract the Legendary affixes.TOP
