If you want to level up rapidly in Diablo 4, you'll need to make the most of the first few hours that you spend playing the game. There are a number of different ways to grind your way through the game and earn a lot of experience to level up more quickly, despite the fact that it isn't as crunchy as previous Diablo games. It is recommended that players spend the first few hours of the main campaign avoiding the majority of the main campaign's content. Check out PC Gamer's comprehensive guide to Diablo 4 to learn where to find mounts, gems, and other useful cheap Diablo 4 items, regardless of whether this is your first time playing the Diablo series or you are a seasoned pro at the game. In any case, the following are the most efficient ways to farm experience and gold when first starting out.

How to gain experience and level up from 1 to 50.
In Diablo 4, there are a number of different ways to rack up additional experience points; however, if this is your first character, the following are the most important ways to do so:

1. Increase the level of difficulty you play at

2. Form a coalition with the other players

3. Accomplish all of the events, dungeons, and sidequests

4. Elixirs can be crafted and used

The benefits of renown
If you start the game on the Veteran difficulty, you will receive a 20% increase in XP from all sources. In all honesty, the Veteran difficulty is not that much more difficult than the Adventurer difficulty. A second easy way to gain an advantage is to work together with other players; however, this does not mean that you have to be friends with these other players. It is simple enough to go to the social section of the menu, cycle to local to find the person you are looking for, and check to see if they are already in a party if you find someone who is adventuring out in the world or playing solo. This will grant you an additional 10% increase, allowing you to level up more quickly.

Elixirs are another option for you because, in addition to the specific bonuses that they grant to the resist types that you have, they also provide a flat 5% XP increase boost at their basic level. Because it is so simple to make an Elixir of Cold Resistance, it is highly recommended that you keep one brewing at all times, regardless of whether you are participating in dungeons or events. Oddly enough, it seems that alternating between public events and dungeons is a much better method to level up than completing the main quests. This is probably because you face a greater number of foes in dungeons and public events.

The Anica's Claim dungeon is an excellent place to farm due to the fact that it is structured as a series of loops. These loops feature a large number of powerful Animus Carrier enemies and elites. These enemies give respectable experience and drop a large quantity of loot. After completing the dungeon, the reset will only take about a minute, but if you don't make it to the final boss, you can warp out, wait a short while, and then come back to fight the enemies again. If you don't make it to the final boss, the dungeon will reset immediately. You will also gather a lot of gear that you can sell, stash, or salvage when you do this, and returning to any city will allow you to do any of those things. This is quite convenient. Keep in mind that you can always press T and return through the same portal to warp back to a town or city at any time, though this option will be removed if you leave the settlement on foot or horseback.

To gain access to Anica's Claim, you will initially be required to finish the Malnok Stronghold in the Fractured Peaks, which is located to the east of Kyovashad.
If you decide to go with the dungeon farming method, keep in mind that certain features, such as Whispers of the Dead or mounts, are connected to the main storyline. In order to access these features for subsequent characters, you will need to finish the campaign at least once with one of your characters. It is also important to note that Blizzard has reduced the likelihood that elite enemies will spawn in certain dungeons. At this time, it appears that Anica's Claim will not be affected, in part because of the objective; however, it is important to keep this in mind in case there are any further modifications.

How to gain experience once you've reached level 50 and beyond
After reaching level 50, the rate at which you level significantly slows down. After you have completed the main storyline and the capstone dungeon in the Cathedral of Light, you will be able to raise the difficulty of your world even further to Nightmare and Torment, both of which offer a significant increase in experience points but are much more challenging.

Once you have reached level 50, the following are your best options for gaining experience:
Activities of the Helltides Legion
Nightmare Dungeons: Whispers of the Dead is a role-playing game.
Even though Helltides and Legion events appear on a timer, you won't be able to farm them indefinitely because of this limitation. However, they will give you decent experience once you reach level 50 and higher. Even though Nightmare Dungeons don't give a lot of experience points right now (though this will change soon), it's still a good idea to run them because you can earn glyph experience and there's a chance you'll find unique D4 items.

In a similar vein, the Whispers of the Dead hand-in does not provide a staggering amount of diablo 4 items at higher levels; however, you will still be traversing areas that are packed with a large number of foes. It is surprising how much you will gain by simply carrying out the objectives to obtain your ten Grim Favors. You will also gain some potentially decent loot if you are still looking to equip your character, so it is a win-win situation.
