So you've finished Diablo 4's campaign, but you realized you're only level 45 or so. You're wondering what in the world you should do to finish reaching the progression milestone that is level 50. After all, level 50 is when the second half of the game starts. If this is you, and you're lost without all reason, then you've come to the right guide, reader. Take a load off and give this a read. You'll be thanking yourself after.
How to reach level 50 after completing the story in Diablo IV
Diablo 4's game world is massive, especially for an isometric style. It is full of all sorts of content, world quests, dungeons, and events, all going on around the same time. While the main story of Diablo 4 does give a ton of experience, once it's over, you'll have to rely on these other activities to reach the big level 50. If you've completed the campaign without reaching level 50, then there's a very good chance that you've skipped a lot of quests and dungeons.
Aspect Dungeons litter the game map and are huge experience grinders for the level-lacking. Since they provide you with permanent Aspects, they are an efficient way to kill two birds with one stone. Then, there's also the matter of the additional skill points that come from area renown. Renown is gained from completing activities in a given area, so there's plenty for you to grind there as well, giving you experience to boot.
World Events also give huge bursts of experience, along with potential Legendary items and Murmuring Obals, which will help you get more legendary items in the future, especially if you're hoarding them. This is another way to get experience, while still progressing in something worthwhile.
Really, the key is to find where you're lacking most in Diablo 4, and focus on progressing that area. Experience just comes naturally, so don't focus too much on that. If you prioritize Skill Points, Aspects, or even Renown farming, you'll find level 50 really isn't that far away.
