In Dishonored 2, finding collectibles like runes is essential for enhancing your supernatural abilities and creating versatile character builds. One particular rune during Mission 2, Edge of the World, causes confusion because it appears trapped behind a sewer grate near the canal. Players often wonder how to access this hidden item without alerting nearby guards or wasting resources.

Finding the Canal Sewer Rune in Mission 2

During the Edge of the World mission, using the Heart will lead you directly toward the canal area near the Overseer's outpost. As you approach the water flow, you will spot a rune glowing behind a metal sewer grate embedded in the wall. Although it looks like you need a secret key or rat possession power, reaching inside directly is impossible.

Many players attempt to find an alternate passageway under the streets or waste time trying supernatural teleports. However, the environmental puzzle is designed around simple mechanical interaction rather than magic.

How to Easily Retrieve the Sewer Rune

To release the trapped collectible, equip your crossbow or pistol and look closely at the wooden blockage behind the grate. Shooting the horizontal wooden board will instantly shatter the debris and free the trapped item. Once destroyed, the flowing water carries the rune straight out into the open canal where you can safely retrieve it.

Using a crossbow bolt is the recommended stealth strategy because it creates minimal noise for nearby guards. Players pursuing high-chaos playthroughs can also toss a grenade or explosive to dislodge the wooden barrier quickly.

Upgrading Your Abilities with Recovered Runes

Collecting every rune allows players to unlock new powers or upgrade existing skills on the Void skill tree. Early game runes are vital for acquiring movement abilities like Blink or Far Reach, which make future exploration significantly smoother. Spending your hard-earned runes wisely ensures your character adapts to either non-lethal stealth or open aggression.

Understanding how environmental destruction works in Karnaca makes finding hidden secrets much easier throughout the game. By mastering simple solutions like destroying barricades, players can maximize their power potential without unnecessary backtracking.
