Summary
There area lotof different systems packed intoDiablo 4.From classes,skill trees, and Paragon glyphs,to enchantments, buffs, and Legendary Aspects, the number of things players have to keep track of - both in terms of damage numbers and good ol' inventory space - can be overwhelming. Even once they reach the late game, more systems are thrown at them. Thankfully, ignoring the less crucial ones is both easy and not overly detrimental when crafting a solid build.

One such less-crucial system isDiablo 4’schallenges. These tasks cover a wide array of gameplay actions. Some are as simple to complete as players upgrading their healing potion for the first time, or conquering a Stronghold. Others are much more difficult. While the reward of a new title isn’t all that enticing, completing these challenges also rewards a large chunk of XP, which is much more valuable. The game’s toughest challenges will require players to make a conscious effort to complete them and gain that XP.
Updated Jun 05, 2025 by Evan Regan:There is simply not enough time in the day to cover every single difficult challenge that Diablo 4throws at its players. The most challenging of the bunch were included here in the original publication, but as the game has evolved and player counts have dwindled, only the most stalwart heroes in Estuar remain in the game’s servers on the regular.

As such, when a challenge poses problems for even those seasoned players, it probably deserves to be mentioned.
13The Heroic Roster
Reach level 100 with every class.
For many of these challenges, the biggest obstacle players will face in completing them is time. Such is the case with “The Heroic Roster,” which requires players to level up every available class to the game’s current max level: level 100.
Getting even one class to level 100 takes hours upon hours of playtime. Doing so with all 5 classes is something only the most dedicated and unwavering players will accomplish. Thankfully, every class feels completely different to play as, which can certainly help prevent the gameplay from getting stale while chasing down this challenge.

12Endangered Species
Kill one of each wildlife.
This is one of those cases where players will have to go out of their way to complete a challenge. Wildlife inDiablo 4tends to blend into the background, and since killing themdoesn’t grant any gold or loot drops,it’s easy to start ignoring them entirely.
Not only can players not do that if they want to complete this challenge, but they’ll also need to keep track of which wildlife species they’ve killed and then track down the ones they’re missing. Then they need to wait for the game’s RNG to spawn the wildlife while they’re nearby. It’ll take some doing to unlock it.

11Champions No More
Kill 3 Elite monsters in 30 seconds.
Elite monsters have earned that title for a reason. They’re typically just standard enemies with a chunky health bar and a status effect or two that they steadily inflict on the player. Usually, they’re thrown in among a mob of standard enemies.

The thing is, there’s usually only one Elite monster in any given mob. That changes in Nightmare Dungeons, but still, just finding a mob with 3 Elite monsters is a challenge in itself. Then, the player has to kill all of them in quick succession. 30 seconds to be exact. Their best bet is to focus damage on each one until their health is almost gone, then switch to the next one, and finally finish them all off with a few quick blows. That, or just build an extremely overpowered character. Neither of those options is particularly easy though.
10Swift Delver
Complete a dungeon in 2 minutes.
Any player who’s completed a dungeon inDiablo 4knows that they’re pretty time-consuming. Most start out with a numbered objective - like destroying 2 altars - which requires thorough exploration to complete, and that’s just to unlock the path to the dungeon’s boss.
Now imagine completing that objectiveanddefeating the dungeon boss in under two minutes. That’s what “Swift Delver” asks of players. Many will complete every dungeon in the game and never come close to conquering this challenge. It will require a mix of luck, skill, and knowledge for them to even have a chance.

9Swift Destroyer
Kill 45 monsters within 8 seconds.
Combat inDiablo 4is a fast and furious affair. Many times, players won’t be fully aware of exactly how many enemies are on screen at any time, and because their abilities will clear through many of those enemies in a heartbeat, it doesn’t really matter. At least, not unless those players are going for the Swift Destroyer challenge.
Mobs inDiablo 4are big, but rarely are they so big as to contain 45 monsters. As such, any players chasing this challenge will likely need to lure two or three enemy mobs into a single location and then unleash all of their character’s most damaging abilities to take them all down swiftly. 8 seconds isn’t all that much time to work with, so some luck will need to be involved, even forthe most overpowered builds out there.

8Estuar Wanderer
Explore all of Estuar.
Diablo 4’smap is no joke. Each of its five regions is massive, containing dozens of dungeons and sidequests as well as a handful of Strongholds, not to mention at least one major city and several small towns.
To unlock the “Estuar Wanderer” challenge, players will need to exploreevery inch of the game’s map.Thankfully, they don’t need to complete everything on the map as well, simply discovering everything is enough, but that’s still a tall task. For their efforts, players will be rewarded with a set of Mount Armor as well as some XP when they complete this challenge.

7Nightmare Conquerer
Complete all Ancestral Nightmare Dungeons.
There are dungeons,there are Nightmare dungeons,there are Sacred Nightmare dungeons, and then there are Ancestral Nightmare dungeons. These last iterations are some of the hardest dungeons the game has to offer, only made worthwhile byproviding the game’s best lootas a reward.
To unlock this challenge, players will need to complete every Ancestral Nightmare dungeon in the game. Every single one of those dungeons will put up a fierce challenge, likely requiring multiple attempts to conquer. There are 30 in total, so get to work.

6Evasive Maneuvers
Complete a Nightmare dungeon without taking damage.
To be completely honest, we’re not sure how this challenge is even possible. Taking damage is par for the course inDiablo 4.Even the most standard, unthreatening mob is likely to land a single hit when engaged with the player simply due to the cooldowns attached to both defensive skills and dodges, and the chaotic nature of the game’s combat.

Yet, to complete the “Evasive Maneuvers” challenge, players must conquer an entire Nightmare dungeon without taking a single hit of damage. That includes the fight with the dungeon boss at the end. No challenge on this list will require more luck than this one.
5Trophy Hunter
Kill all extremely rare monsters in the Open World.
On top of Elite monsters, there are also monsters found roamingDiablo 4’smap that are considered “extremely rare.” They can be found in specific regions of the game’s map, but there is no guarantee that they will spawn when the player wanders by.
To complete this challenge, players need to not only track down all 15 of these monsters but also kill every single one. They are still Elite monsters, but they usually bring with them a unique ability that makes them an even tougher opponent. The one perk is that they have a high chance of dropping Legendary gear when defeated.

4Journeyed Slayer
Kill every World Boss in Hardcore mode.
Of all the enemies the game has to offer, no battles are tougher thanDiablo 4’sWorld Bosses. These 3 enemies spawn at random around the game’s world and make all other boss fights look like child’s play. They have huge health bars, devastating attacks, and tend to summon an army of minions to their side.
There is also a difficulty that players unlock after completing the game’s campaign called Hardcore mode. This mode grants players absolutely no mercy. If their character dies at any point, they die for good. Back to the character select screen, back to level 1. World Bosses require a strong, high-level character just to attempt, so even getting to the point where fighting them is possible will take some time. Imagine putting in all that work, taking on the first World Boss, and then dying. It’s a devastating concept. Now go do it 3 times.
