Ultimate Guide to Shield Runes in Doom: The Dark Ages – Effects, Strengths, and Builds

Doom: The Dark Ages shakes up its signature combat with a new shield mechanic, letting the Doom Slayer block, parry, charge, and throw the shield to stun enemies.

As you progress, you unlock shield runes—powerful upgrades that activate when parrying Hell Surge attacks, turning defense into offense with effects like shockwaves, daggers, turrets, or lightning.

With Hell Surges growing more intense later in the game, choosing the right rune becomes key to survival. This article breaks down each rune, its upgrades, and how to pick the best one for your playstyle.

Some players may notice that the Runes page is completely locked at the start of the game, leading to concerns that they might have missed a critical upgrade early on.
