Wondering how Shield Runes work in Doom: The Dark Ages? Here’s when you unlock them, how they work, and every Rune available in the campaign.
How to Unlock and Use Shield Runes in Doom: The Dark Ages
With all the chaos flying around in Doom: The Dark Ages, keeping your head on straight is tough—especially with new weapons, upgrades, and secrets constantly being thrown your way. One key system that takes the Slayer’s shield to a whole new level is Shield Runes, and if you’ve seen that locked Runes page early on and thought you missed something—don’t worry. You haven’t.
Shield Runes are unmissable upgrades that get introduced later in the story, and they make the shield way more than just a defensive tool. Here’s how to unlock them and what each Rune can do.
🛡️ How to Unlock Shield Runes
You won’t be able to use Shield Runes right away—so don’t stress if the Rune page looks empty at the beginning of the game. Shield Runes unlock automatically in Chapter 9 of the main story. As soon as the level starts, you’ll get access to your first Rune: Ground Fissure.
From that point on, new Runes will unlock as you continue the campaign, and you won’t need to find them manually—they’re built into story progression.
⚡ What Do Shield Runes Do?
Shield Runes augment your shield’s parry, turning a basic block into a flashy offensive move. Anytime you successfully parry a green projectile, your equipped Rune will activate a powerful ability tied to that Rune.
Each Rune can also be upgraded using gold, letting you enhance damage, range, duration, and more depending on the Rune’s effect.
🔥 All Shield Runes & Unlock Chapters
Here’s a quick list of every Shield Rune in the game and where you get them:
- Ground Fissure (Chapter 9)
Creates a damaging fissure in front of the Slayer when a parry is timed correctly. Great for crowd control. - Holy Swarm (Chapter 11)
Summons a swarm of holy projectiles that home in on enemies after a parry. Perfect for thinning out smaller foes. - Auto Turret (Chapter 12)
Drops a temporary turret that auto-targets demons nearby. Great for area denial or extra DPS during big fights. - Heaven Splitter (Chapter 14)
Deals a powerful vertical slash of energy, carving through enemies in a line. Best used on heavy targets or choke points.
💸 Should You Upgrade Runes?
Absolutely. On harder difficulties, parrying becomes essential, and Rune upgrades let you add serious offensive utility to every successful block. You can customize which Rune suits your playstyle best, whether you prefer keeping pressure on enemies or controlling space.
So if you’ve been wondering when you’ll finally start messing with Shield Runes—just hang tight until Chapter 9. Once you unlock them, you’ll see how much of a game-changer they are in Doom: The Dark Ages.
