D4 HC CODEX ASPECTS

The Codex of Power Aspects are earned through completing Dungeons or parts of the Campaign. These will be an important part of any D4 hardcore leveling because they will add power to each build to help with survivability, mobility, or kill speed. Because these aspects are guaranteed to be earned versus hoping for a legendary item to drop we can plan out which ones we want to use before starting our characters.

There are many different types of Aspects… Offensive, Defensive, Resource, Utility and Mobility. Here is a list of Codex of Power Aspects that will be useful for hardcore players early game. 

This list focuses on options that will help survive hardcore and is broken down by class, starting with the Aspects available to every class.

Check out the HC Build Guides for which aspects are used on a specific build early on.
