If you’ve spent even a few hours running through the blood-soaked medieval battlefields of this iconic DOOM total conversion, you know how quickly a bad upgrade pick can turn a winning run into a demon snack. I’ve put over 70 hours into the mod across every difficulty level, and I’ve tested every single option to figure out which picks actually move the needle for casual and hardcore players alike. This breakdown of Doom the Dark Ages upgrades cuts through the noise to highlight the picks that will help you clear even the hardest hidden boss fights without wasting your hard-earned soul shards.
Top Doom The Dark Ages Upgrades for Early Run Success
Early game is the most unforgiving part of any run, because you start with only a rusted short sword and a weak crossbow, and demons hit hard enough to take you out in two hits if you’re playing on Hard or Nightmare difficulty. You don’t have a lot of soul shards to spend in the first two upgrade shrines, so you need to pick options that give you immediate value, not late-game payoff. Prioritize survivability over raw damage in the first 20 minutes of your run, because even the best weapon won’t help you if you get one-shot by a charging Hell Knight variant.
- Iron Skin T1: Cuts all incoming damage by 15% for only 120 soul shards. This is a no-brainer first pick for every build, no matter what weapon you plan to main later on. It even stacks with armor pickups, so you can push damage resistance up to 40% before you hit the third level.
- Crossbow Quick Draw: Cuts crossbow reload time by 30% and lets you fire two shots in quick succession before needing to reload. Most early-game demons are weak to piercing damage, so this upgrade lets you take out groups of imps and possessed peasants before they get close enough to hit you.
- Soul Shard Booster: Increases the number of soul shards dropped by killed enemies by 20% for the rest of the run. It costs a little more than the other early picks at 180 shards, but it pays for itself by the end of the second level, and lets you unlock higher tier upgrades much faster later on.
You might be tempted to pick melee damage upgrades first if you prefer close combat, but don’t do it. Early demons are fast and attack in groups, so you’ll take far too much damage before you can get close enough to hit them unless you have that base damage resistance first. I learned this the hard way on my first 10 runs, where I’d die to a pack of imps halfway through level 2 because I skipped Iron Skin for a sword damage buff.
Mid-Run Upgrade Picks for Specialized Builds
Once you hit level 4, you’ll start seeing tier 2 and tier 3 upgrades show up in shrines, and you’ll have enough soul shards to start leaning into a specific playstyle. A lot of players make the mistake of picking random high-tier upgrades that don’t match their main weapon, and that’s a surefire way to waste hundreds of shards on perks you’ll never use. First, decide if you want to run a melee, ranged, or magic build before you pick any mid-game upgrades, so every pick supports your core damage output.
For melee players, Blood Rage T2 is the best pick by a wide margin. It gives you a 40% damage boost for 10 seconds every time you land three consecutive melee hits, and it refunds 5 health for every kill you get while the buff is active. I’ve used this upgrade to clear entire rooms of heavy demons without using a single health pickup, and it pairs perfectly with the greatsword or battle axe weapons you unlock around level 5. Ranged players should prioritize the Longbow Piercing perk, which lets your arrows go through up to three enemies at once, while magic builds get the most value out of Mana Regen T2, which cuts down the time you have to wait between casting fireball or frost spells by half.
There are a few mid-run upgrades you should avoid no matter what build you’re running. The Gold Find perk is useless unless you’re playing the custom loot-focused game mode, because gold only buys cosmetic skins that don’t impact gameplay. The Fall Damage Reduction perk is also a waste of shards, because there are almost no high ledges in the main campaign maps, and you can easily avoid fall damage by jumping carefully anyway. Save your shards for perks that directly impact your damage or survivability, and skip these novelty picks entirely.
Late-Game Upgrades to Beat Final Bosses
The last three levels of the main campaign throw every type of demon in the mod at you, including several hidden mini-bosses and the two endgame bosses: the Possessed Bishop and the Hell Wyrm. These fights have multiple phases, and they deal enough damage to take out even a high-health build in just a few hits, so your late-game upgrades need to balance damage output and survivability perfectly. You’ll have most of your build locked in by this point, so you only need to pick 2-3 more upgrades to push you over the finish line.
Divine Protection T3 is non-negotiable for any build running on Hard difficulty or higher. It gives you one free revive per run, with full health and mana, if your health drops to zero. I can’t tell you how many runs I’ve saved with this upgrade, especially during the Hell Wyrm’s second phase where it spams unavoidable area-of-effect fire attacks across the entire arena. If you don’t pick this, you’re one mistake away from losing 2 hours of progress, no matter how good your gear is.
For damage, the best late-game upgrade depends on your build, but the Unstoppable Force perk for melee builds, Rapid Fire Enchantment for ranged builds, and Spell Echo perk for magic builds all give you a 60% damage boost to your core attack type, enough to burn through boss health bars in half the time. Don’t waste your shards on low-tier upgrades at this point, even if they look tempting. Save up for the T3 perks, because they’re the only ones that make a noticeable difference in the final fights. I once tried to skimp on a T3 damage perk for a cheaper T1 health buff, and I spent 20 minutes chipping away at the Possessed Bishop’s health bar before I finally ran out of healing items.
Common Upgrade Mistakes to Avoid
I’ve made every possible mistake with upgrades during my time playing the mod, so I know which errors are the most common for new players. The biggest mistake I see is people picking upgrades based on how cool they sound, instead of how well they work with their current build. For example, the Fire Sword Enchantment sounds great, but it’s completely useless if you’re maining a crossbow build, and it wastes 300 soul shards you could have spent on a useful ranged perk.
Another common mistake is saving up all your shards for T3 upgrades instead of picking cheaper T1 and T2 upgrades early on. A lot of new players think they should hold out for the highest tier perks, but if you don’t pick low-tier upgrades early, you’ll struggle to kill enemies fast enough to earn the shards you need for T3 perks later. It’s always better to pick a useful cheap upgrade than to hoard shards for something you might not even see before you die.
Finally, don’t pick duplicate upgrades unless the game explicitly says they stack. Most upgrades in the mod don’t stack, so picking Iron Skin T1 twice won’t give you 30% damage resistance, it’ll just waste your shards. Pay attention to the perk description before you buy it, and if it doesn’t say “stacks with previous tiers”, don’t buy a duplicate if you already have that perk unlocked. I’ve seen new players waste hundreds of shards on duplicates because they didn’t bother reading the short description, and it almost always ends their run early.
At the end of the day, the best Doom the Dark Ages upgrades are the ones that fit your playstyle and help you cover the weaknesses of your current build. You don’t have to follow this guide exactly, but sticking to these recommendations will help you avoid wasting shards on useless perks and make your runs much smoother, even if you’re playing on the highest difficulty. Spend a little time testing different perks on casual runs to find what works best for you, and you’ll be beating the final boss in no time.
