So You Want to Unlock the Terrifyingly Holy Harrow? Here’s How I Did It (and How You Can, Too)

Warframe’s sandbox has always been a glorious blender of sci-fi, fantasy, and everything in between. But when Halloween rolls around and you start craving something that makes even the Infested look cuddly, you need a frame that bleeds gothic horror. Enter Harrow, the creepy space priest who turns self-flagellation into a team buff. Yes, he’s the one who screams “Rap. Tap. Tap.” in the Chains of Harrow quest and gives everyone nightmares. Naturally, you’re wondering: how do I get this edgy powerhouse without losing my sanity? I’ve been through the wringer, and I’ll walk you through every step—minus the therapy bills.
First, let’s tackle the elephant in the Orbiter. Why would anyone willingly farm a frame whose entire lore revolves around trauma and child souls? Because Harrow can make your weapons crit harder than a Corpus CEO’s bonus, heal allies by emptying his own shields, and chain enemies in place while screaming \u201cBELIEVE!\u201d He’s a support frame that out-damages half the roster when built right. Convinced? Thought so.
There are two ways to obtain Harrow: swipe your Platinum card or roll up your sleeves and farm until your eyes bleed. I’m a glutton for punishment, but I’ll explain both so you can decide how much you value your real-life time.
The Platinum Path: Instant Gratification, No Sweat
If you’re drowning in Platinum from trading Rivens or just want to skip the grind, here’s your express ticket to Harrow-ville. Head to the in-game Market on your Liset and search for Harrow. The base Warframe costs 225 Platinum. That gets you:
-
A fully built Harrow with an Orokin Reactor already installed (because who doesn’t love free double mod capacity?).
-
A Warframe slot, even if you’re already hoarding frames like I do.

But wait, there’s a shinier bundle. For 275 Platinum, the Harrow Reliquary Collection drops, and it’s basically the priest’s Sunday best:
-
Everything from the base package.
-
Harrow Reliquary skin (worth 165 Platinum on its own—so you’re practically getting a discount, right?).
-
Renuntio Speargun Skin (for when you want your speargun to look as holy as a void key).
-
Etheria Chest Plate, Shoulder Plates, and Leg Plates to make your frame look like a walking cathedral.

The upside? Zero tears. The downside? Your wallet might feel slightly violated. But hey, some of us have jobs and families and can’t afford to lose 72 hours of crafting time to RNGsus. No judgment.
The Free-But-Painful Route: Farming Harrow’s Blueprints
If you’re like me and believe that suffering builds character, then welcome to the grind. The biggest cost here isn’t Platinum—it’s your patience and possibly your relationships. You’ll need to craft Harrow’s Neuroptics, Chassis, and Systems; each part requires 12 hours in the Foundry. Then you’ll wait another 72 hours for the main frame to finish. That’s on top of the farming time for the blueprints themselves. Still with me? Good, because the real fun starts now.

Harrow Blueprint: The Free Gift at the End of a Horror Movie
You don’t actually farm the main blueprint. You earn it by completing the Chains of Harrow questline. This quest is a masterclass in atmospheric horror—expect creepy transmissions, shadow children, and a boss fight that makes you rethink your life choices. But before you can even start it, you need to finish The War Within quest, which itself requires Mastery Rank 5. So if you’re a fresh Tenno, don’t even think about Harrow just yet. Go level your frame and come back when you’ve had your first Operator meltdown.

Chassis Blueprint: Void Fissure Massacre
Here’s where the grind begins. The Harrow Chassis Blueprint drops from killed Void Fissure enemies—any faction, any mission type—at a majestic 3% drop chance. I hope you like seeing the same death animations over and over. Statistically, you might need around 33 kills if you’re lucky, but don’t be shocked to find yourself at 300+ kills without the drop. My advice: run endless Survival or Defense fissure missions, and bring a Nekros or Hydroid to squeeze extra loot from corpses. Every dead Grineer is a piñata that might cough up chassis blueprints.

Neuroptics Blueprint: The Spy Mission That Tests Your Stealth (and Sanity)
Welcome to Pago, the Kuva Fortress Spy node. Harrow’s Neuroptics Blueprint drops as a reward from cracking a vault here, specifically in Rotation A (the first vault you successfully hack). The chance is 16.67%, which looks generous until you realize you need to hack at least two vaults consistently to get the best shot. Fail even one, and you might walk away empty-handed—or worse, trigger alarms and get swarmed by Kuva Guardians who laugh at your puny weapons.
Bring a Loki or Ivara, or at least an Operator with proper stealth arcanes. I once tried this with a Rhino and my dignity. Let’s just say I’m still recovering. The Pago vaults are annoyingly well-hidden, so check every vent and memorize layouts before you go in half-cocked.

Systems Blueprint: Defection—The Ultimate Test of Patience
By far the most soul-crushing part of this farm is the Systems Blueprint, which drops from Defection missions. These involve escorting suicidal Grineer defectors to extraction while Infested try to eat them. The Systems blueprint has a 6% chance to appear as a Rotation B reward (escort 6 squads) and a 15% chance as a Rotation C reward (escort 8 squads). Escorting just two squads gets you Rotation A, but that’s wasted here. You have to commit to babysitting for extended periods.
Eight squads sound doable until you realize each squad takes roughly a minute or two, and enemies scale. Failing a defection run means you get nothing. My blood pressure spikes just thinking about it. Pro tip: bring a fast healer like Trinity or a nuke frame to clear paths. And try not to rage-quit when the defectors decide to pathfind into a dead end that looks suspiciously like a trap.

The Alternative: Kuva Survival on Taveuni
If Defection makes you want to uninstall, there’s hope. Kuva Survival on Taveuni (also on the Kuva Fortress) can reward either the Neuroptics or Systems blueprint on Rotation C with a 12% chance each. Here, Rotation C means 15 minutes of survival, then the cycle repeats every 5 minutes. So if you can stay 30 minutes, you might snag both blueprints in one go—provided RNG smiles upon you. The catch? Kuva enemies scale fast and hit hard, plus you’ll be managing life support while fending off liches and Kuva guardians.
I’ve had runs where I got both parts by minute 20, and runs where I stayed 45 minutes and got duplicate Neuroptics. The 12% drop rate feels more like 0.12% when you’re staring at your fifth Harrow Chassis in a row. Still, it’s often less tedious than Defection because at least you’re killing things instead of herding AI that has the survival instincts of a headless chicken.

So Which Route Should You Take?
If you value your time above all else, just buy Harrow. Farming him the free way is a rite of passage that will either forge your patience or scar you for life. I did it to prove I could, and now I have a brand of hatred for Defection that rivals my dislike for Conclave. But when I finally built Harrow, equipped his Reliquary skin, and chained 50 enemies while shouting \u201cRap. Tap. Tap.\u201d in voice chat, it felt almost worth it.
Now go, Tenno. May your drop rates be high and your frustration low. And if all else fails, remember: RNG is just a mindset. A very, very annoying mindset.
While grinding for Harrow might test the limits of your patience, it's all part of the journey in the world of Warframe. Yet, as you dive deeper into the game, you might find yourself pondering over other frames and items, each with its own unique farming challenges. In such times, knowing when to farm and when to purchase can be a strategic choice.
For those moments when you decide to purchase instead of farm, having access to a reliable game price comparison tool can be invaluable. DealNest provides a comprehensive platform to compare prices across various games and in-game items, ensuring you get the best deals. Whether you're a seasoned Tenno or a new recruit, staying informed can enhance your gaming experience without breaking the bank.
