In Old School RuneScape’s Delve encounters, surviving Doom’s car phase becomes increasingly difficult once you reach Delve level eight and beyond. The shockwaves, boulder positioning, and movement timing can overwhelm even experienced players. Fortunately, the “double parking” method provides a consistent and reliable strategy that allows players to control boulder placement while safely avoiding the first two shockwaves during the encounter, while some players may choose to buy OSRS gold as part of their broader account progression planning.

This guide explains exactly how the method works, how to execute it correctly, and how to practice the movement timing until it becomes second nature.

Why Double Parking Matters

At higher Delve levels, Doom’s mechanics become far less forgiving. Incorrect boulder positioning often creates impossible movement patterns or forces players into unnecessary damage. Double parking solves this problem by ensuring both boulders are placed in optimal locations, creating a predictable setup that greatly simplifies the car phase.

The strategy is especially useful for Delves level eight and above, where precision matters much more than raw reaction speed.

Starting Position

The setup always begins on the eastern side of the room. Before the mechanic begins, stand on the marked red tile with the X. This positioning is critical because it manipulates where the two boulders land.

Once the boulders are thrown toward you, do not panic and move immediately. The timing window is extremely important.

Instead, watch the first boulder carefully. You are waiting for the exact moment when the first boulder dips downward just before exploding. That visual cue signals the correct timing to begin running north toward the white tile marked with an X.

If your timing is correct, the boulder should explode precisely as your character begins moving north.

Understanding the Timing

Most players fail this mechanic because they move either too early or too late. The key is understanding that your “true tile” matters more than your character model animation.

As soon as your true tile reaches the northern white tile, you have two possible options:

· Melee punish Doom if the opportunity is available

· Step onto a nearby shadow tile to avoid incoming damage

The mechanic becomes significantly easier once you trust the timing rather than reacting emotionally to the explosion animation.

If you continue struggling with the movement, practice on Delves six and seven first. These lower difficulties give you more room for error and allow you to build muscle memory before attempting deeper runs.

A good indicator that your timing is correct is when the first boulder detonates exactly as your character starts the northward run.

Managing Doom’s Car Phase

Once the car phase begins, positioning becomes even more important.

You can stand on any of the three marked red tiles shown in the standard setup. These tiles manipulate Doom’s movement path and align him perfectly with the first boulder.

Proper alignment is the entire foundation of the double parking strategy.

When Doom reaches the first boulder, immediately stand on the designated tile beside him. This prepares the next movement pattern and sets up the transition toward the second boulder.

At this point, the mechanic becomes surprisingly simple.

All you need to do is step underneath Doom by one tile. Watch Doom carefully during this moment. There are two visual cues that indicate the next movement:

· Doom slightly turns his head

· Doom marks the second boulder

The instant either cue appears, move onto the white tile, then step out of the danger zone as necessary.

Once completed correctly, the second boulder positioning resolves naturally and the dangerous portion of the car phase is effectively over.

Common Mistakes

Many players overcomplicate this mechanic, but most failures come from only a few issues:

Moving Too Early

If you run before the first boulder dips downward, the boulder placement becomes inconsistent and the shockwave timing breaks apart.

Watching the Character Instead of the True Tile

OSRS movement mechanics rely heavily on true tile positioning. Your character model may appear delayed, but your actual tile location determines whether you take damage.

Panicking During Doom’s Rotation

Doom’s head turn and second boulder marking are reliable visual indicators. Trust the cues and avoid spam-clicking.

Ignoring Lower-Level Practice

Practicing on Delves six and seven helps players learn the rhythm safely before attempting high-pressure deeper runs.

Using the Entire Room

For deeper Delves, room management becomes increasingly valuable. One advanced optimization is copying the same tile setup onto the opposite side of the room.

Doing this allows you to utilize the entire arena rather than restricting yourself to a single side. This extra flexibility becomes extremely useful during longer encounters or more chaotic runs.

Final Thoughts

The double parking method turns one of Delve’s most frustrating mechanics into a controlled and repeatable sequence. While the setup may feel intimidating initially, the strategy becomes very consistent once the movement timing clicks.

Focus on the first boulder timing, trust your true tile movement, and learn Doom’s visual cues during the car phase, while some players also think about resource efficiency such as “cheap OSRS gold” when planning their progression. After enough practice, the entire sequence becomes almost automatic. With enough repetition, you will find yourself surviving deeper Delves far more consistently while taking significantly less unnecessary damage.
