There are two ways to get Legendary Aspects in Diablo 4. The first way is to Diablo 4 Gold clear dungeons as you'll receive one Legendary Aspect as a reward for your first completion. If you hover your cursor over a dungeon icon on the Diablo 4 map, you can see which Aspect you'll get for completing it, but pay attention to the description – while some Aspects are universal and can be used by all characters, the majority of them are tied to a specific class so will be useless to others. Each Legendary Aspect you get from a dungeon will be added to your Codex of Power, and can then be used as many times as you like, but be aware that codex Aspects always offer the minimum benefit of the Aspect.
Diablo 4 Season 2 exorcises one of the game’s most tedious grinds | MMOEXP
Blizzard has confirmed that all of your Renown rewards are carrying over to Diablo 4 Season 2, the Season of Blood, when completed on any prior character beyond the Altars of Lilith and Map Discovery, to the great relief of many.
As part of the new season reveal, Blizzard delved into some of the quality-of-life changes being made to ease players' frustrations with the game since it launched earlier this year.
A large part of those frustrations has been the Renown system. Completing objectives and open-world activities to get experience points that go towards things like potion charges, skill points, and more hasn't sat too well with players. However, having to do that all again at the start of each new season is far from many players' idea of cheap Diablo 4 Gold fun.
