Aspects are the pieces that make a Diablo 4 build feel like your own. One can turn a basic skill into a main damage source; another might fix a resource problem or keep you alive when a boss gets messy. That is why players checking D4 items should pay attention to an item's Aspect as well as its affixes. You'll notice it pretty quickly: a weapon with slightly lower damage can still be the better choice if it carries the power your build actually needs.
The Occultist's real job
The Occultist is where you place an Aspect onto eligible Legendary gear, but the process is much less fiddly than it used to be. In early versions of the game, extracting a power meant sacrificing a Legendary item and carrying a single-use Aspect around in storage. That system is gone. Now, when you salvage a Legendary at the Blacksmith, its Aspect is added to your Codex of Power. If the roll is stronger than the one you had, the Codex keeps the better version. No stash full of duplicate powers. No second-guessing whether to save one "just in case."
What changes when you imprint
Imprinting replaces the Aspect already on a Legendary item, so it is worth stopping for a second before clicking through the menu. Pick gear with the affixes, item power, and upgrade potential you want to keep. The Aspect is there to support that item, not rescue a weak one.

Using dungeons without wasting time
Dungeons still matter because many of them unlock specific starting Aspects in the Codex. They are reliable, even if the first version is usually at the lower end of its range. That is often enough. A Sorcerer who needs a defensive trigger, or a Barbarian short on Fury, does not need to wait for a perfect drop before the build starts working. A sensible route looks like this.
Check the Codex for the Aspect tied to your main skill or survival plan.
Pin the dungeon and clear it when the reward has an immediate use.
Salvage duplicate Legendaries instead of filling your stash with them.
Re-imprint only when the new item is a real upgrade.
Keeping costs under control
Gold and materials can disappear faster than expected once you start swapping powers around, especially after a good run of upgrades. Save your expensive imprints for gear that is likely to stay equipped for a while, and use dungeon versions on temporary pieces. If you need extra currency for a round of crafting, players who choose to buy Diablo IV Gold can keep their focus on testing gear choices, then spend it carefully on the items that genuinely improve the build.
