In Diablo IV, Legendary Aspects are unique affixes found on legendary items that drastically change how your skills and abilities behave. They are the Diablo IV Items backbone of high-tier character customization, giving builds their distinct power spikes by enhancing skills, adding special effects, or altering key mechanics of your class.

What Are Legendary Aspects?

Legendary Aspects are special modifiers tied to gear. When an Aspect is present on a legendary item, it appears in orange text in the item tooltip and grants effects that go far beyond regular affixes. These might boost damage, improve defenses, generate resources, or introduce new combat interactions that a build revolves around.

There are five major categories of Aspects:

Offensive (boost damage or offensive utility)

Defensive (improve survivability)

Resource (affect resource gain/flow)

Utility (varied benefits like crowd control or synergy boosts)

Mobility (movement boosts or tactical repositioning)

Each category can only be applied to certain gear slots — for example, Offensive and Resource aspects are most often placed on weapons, rings, or amulets, while Defensive might go on armor or helmets.

How to Get Legendary Aspects

There are two reliable ways to obtain Aspects:

Dungeon Clears — Completing a dungeon for the first time unlocks its associated Aspect directly into your Codex of Power. You can then imprint that Aspect indefinitely.

Legendary Drops — Many legendary gear pieces drop naturally in the world (from Nightmare Dungeons, Helltides, The Pit, Strongholds, world bosses, etc.). Salvaging these items adds their Aspect to your Codex if it’s new or upgrades it if it’s a better roll.

Once in your Codex of Power, Aspects become part of your account collection and can be used on any character in the same realm.

The Codex of Power

The Codex of Power is essentially your account-wide index of all Legendary Aspects you’ve unlocked. It lives in the Collections menu (open with “Y”), where you can view, filter, and select which Aspects you want to imprint onto your gear.

Key points about the Codex:

Aspects unlocked by dungeons start at the lowest roll and can be strengthened by salvaging better-rolled versions.

Aspects saved in the Codex can be imprinted infinitely (as long as you can pay the gold and materials).

Upgrading an Aspect’s rank in the Codex improves the power of that Aspect when used on gear.

Imprinting Aspects & Build Strategy

To apply or “imprint” a Legendary Aspect onto an item, visit the Occultist NPC in any major city. The Occultist’s interface lets you choose a base item and then pick an Aspect from your Codex to infuse — turning rares into legendaries or swapping powers on existing gear.

Best practices:

Prioritize high-impact Aspects for your build’s core mechanics.

Focus on completing dungeons tied to must-have Aspects early.

Salvage unwanted legendaries to upgrade Aspect ranks in the Codex.

Place the most important Aspects on slots with bonus effects — like amulets (+50%) or two-handed weapons (+100%) — for maximum benefit.

Whether you’re grinding Nightmare Dungeons or planning endgame builds, mastering Legendary Aspects and the Diablo IV Items for sale Codex of Power is crucial to maximizing your effectiveness in Diablo IV Season 11. Build smart, farm wisely, and let your Aspects lead the way to Sanctuary’s toughest challenges.
