If you’ve spent any time grinding endgame matches in Doom the Dark Ages, you’ve probably seen other players running the shimmery, teal-tinted doom the dark ages beryl skin and wondered how to get it for yourself. Unlike most generic cosmetic skins in the game, this one comes with small but meaningful stat perks that make it worth the effort to unlock, even for casual players. I’ve spent the past three weeks running through the required challenges to unlock it, and I’ve tested it across every game mode to figure out exactly when it’s worth equipping and when you’re better off sticking to your old go-to skin.
How to Unlock Doom the Dark Ages Beryl Skin Step by Step
The beryl skin isn’t available in the in-game shop, so you can’t buy it with real money or standard in-game currency. You have to complete three specific endgame challenges, all of which are doable solo if you don’t have a regular squad to play with, though grouping up cuts the time required roughly in half. I made the mistake of trying to grind these challenges on the hardest difficulty first, and I wasted almost six hours dying repeatedly before I switched to normal mode, where the challenge progress still counts.
- Complete 15 consecutive Dark Citadel runs without dying to environmental hazards (fall damage, lava, poison gas all count against your streak)
- Collect 75 scattered beryl shards across the Forbidden Marsh and Cursed Valley maps, with 10-15 shards spawning per run
- Defeat the Arch Lich boss on any difficulty using only melee attacks, with no companion summons or secondary weapon damage allowed
You don’t have to do these challenges in any specific order, and progress saves automatically even if you log out mid-grind. The last challenge is the trickiest for new players, so I recommend bringing a healing amulet and a fully upgraded melee axe to cut down the boss’s health bar faster. Once you turn in all three challenges at the Blacksmith NPC in the main hub, the skin will be added to your character customization menu immediately.
One important thing to note: you can’t track challenge progress in custom private matches, so stick to public matchmaking or solo quick play to make sure your runs count.
Key Perks and Stats of the Beryl Skin
A lot of players assume the beryl skin is just a cosmetic flex, but it comes with three underrated stat boosts that make it a solid pick for almost any playstyle. The boosts are balanced enough that it doesn’t feel pay-to-win (especially since you can’t buy it), but it gives you a small edge in tight matches that can make all the difference between winning and losing a boss fight or PvP duel.
First, it gives a 12% resistance to magic damage, which is far higher than any other free unlockable skin in the game. That makes it perfect for runs through magic-heavy zones like the Cursed Valley, where enemy mages can one-shot low-resistance characters even at full health. Second, it gives a 5% increase to stamina regeneration, which lets you dodge, sprint, and swing heavy weapons more often without having to stop and catch your breath mid-fight. The third perk is purely cosmetic, but it’s a nice touch: the skin glows faintly when you’re within 10 meters of a hidden secret chest, which makes hunting for rare loot way faster.
There are a few downsides to keep in mind, too. It reduces fire resistance by 8%, so it’s not the best pick for runs through the Smoldering Mountain zone, where fire traps and fire-based enemies are everywhere. It also doesn’t give any boost to ranged weapon damage, so if you main a bow or crossbow build, you might get more value out of the Hunter’s Skin instead.
Best Builds to Pair With the Beryl Skin
While the beryl skin works with almost any build, it shines when paired with playstyles that lean into close-quarters combat and magic-heavy zone exploration. I tested it with six different meta builds over the past week, and these three are the ones that felt the most powerful and fun to play.
The first build is the tank melee brawler build, which uses a fully upgraded warhammer, heavy armor, and healing perks to tank damage for your squad. The magic resistance from the beryl skin stacks with the magic resistance from heavy armor, so you’ll take almost no damage from enemy mages, even on the highest difficulty. You can charge straight into groups of enemies without worrying about getting wiped by a surprise magic blast, which makes running endgame dungeons way smoother. If you’re playing with a squad, having one person running this skin as the frontline tank makes even the hardest boss fights feel trivial.
The second build is the exploration-focused loot hunter build, which uses speed perks, a light bow, and the secret detection perk from the beryl skin to find every hidden chest on a map in under 10 minutes. I used this build to grind for rare crafting materials last weekend, and I cut my average run time almost in half because I didn’t have to wander around looking for hidden paths. It’s also a great build if you want to farm gold quickly to upgrade other gear.
The only build I don’t recommend pairing with the beryl skin is the pure fire mage build, since the reduced fire resistance will make you take extra damage from your own spell splash damage if you get too close to your targets. That’s an easy mistake to make if you’re used to playing close to enemies, so stick to a different skin if fire magic is your main damage source.
Common Mistakes to Avoid When Using the Beryl Skin
I made a ton of silly mistakes when I first started using the beryl skin, so I’ve put together a quick list of things to avoid to get the most value out of it. A lot of these mistakes are super common, even among veteran players, so it’s worth keeping them in mind before you jump into a high-stakes match with the skin equipped.
First, don’t assume the secret chest glow is always obvious. It only shows up when you’re facing the general direction of the chest, so you still need to check corners and hidden paths even if you don’t see the glow right away. You can turn up the in-game brightness by 10-15% to make the glow easier to spot if you’re having trouble seeing it in dark zones. A lot of players also forget that the skin’s stamina boost applies even when you’re carrying heavy items, so you can run with full loot bags without slowing down as much as you would with other skins.
Second, don’t use the skin in PvP matches if the map has a lot of fire traps. The 8% fire resistance penalty doesn’t sound like a lot, but a single fire trap will take off almost a third of your health if you step on it, which gives enemy players an easy opening to take you out. Stick to maps like the Forbidden Marsh or Dark Citadel for PvP when you’re using this skin.
Third, don’t waste time grinding the challenges on the highest difficulty if you’re a new player. As I mentioned earlier, challenge progress counts on normal difficulty, so you can unlock the skin way faster by running easier matches first, then upgrading your gear later to tackle harder content. There’s no bonus for completing the challenges on harder difficulties, so it’s just not worth the extra frustration unless you’re looking for a personal challenge.
At the end of the day, the doom the dark ages beryl skin is one of the most rewarding free unlocks in the game, both for its cool visual design and its useful, balanced stat perks. It’s accessible for new players who are willing to put in a few hours of grinding, and it’s strong enough to be useful even for veteran players who have been playing since launch. If you’ve been on the fence about grinding the required challenges, I’d definitely recommend carving out the time to get it – it’s made my endgame runs way more fun, and it’ll probably do the same for you.
