You’ve built Mr. Peeks. Cracked the nursery code. Defeated Baztura and unlocked the Ray Gun Mark II. Now it’s time to channel everything into the ancient, eerie heart of the map: the Serpent Mound. This ritualistic site is where the final phase of charging your Doppelghast containment canister begins. In this bo6 bot lobbies, we’ll guide you through placing the canister, manipulating laser reflectors, fighting elite Doppelghasts, and fully powering the core device needed to unlock your pet companion, Donut.

Step 1: Getting to the Serpent Mound 

The Serpent Mound is a ritual platform located deep beneath the Conservatory, accessible only after obtaining the fully upgraded Ray Gun Mk II and the three canisters from Blog 3. Once you enter the winding staircase behind the hanging vines, you’ll find a large circular chamber with serpent statues, glowing yellow conduits, and a central device with an empty canister slot.

Insert your charged canister into the terminal. A short cutscene-style flash will play—vivid hallucinations, whispering voices, and a glyph of the Doppelghast symbol forming in the air. The room locks down, and the laser phase begins.

Step 2: Solving the Laser Reflector Puzzle 

Now it’s time to manipulate reflector pads to align three beams of light to the central charging device. Think of it as Zombies-meets-Zelda. Here’s the catch: every 60 seconds, a wave of elite Doppelghast Echoes spawns to interrupt your progress.

Here’s how to solve the puzzle efficiently:

• Reflector A (North): Aim it first. It needs to bounce off a silver serpent statue to redirect toward Reflector B.

• Reflector B (East): Use this to reflect upward toward the floating glyph ring above the mound.

• Reflector C (West): The trickiest—this one requires you to shoot its base with the Ray Gun Mk II to rotate it fully. Once it locks in, it’ll complete the tri-beam circuit.

Each successful reflector connection increases the canister’s charge meter on the right side of the mound. You’ll need to hold your position while beams glow brighter and Doppelghasts become faster and more aggressive.

Pro tip: Use a Decoy Grenade or a Kazimir portal right before placing each reflector. This gives you a few seconds of breathing room to get the beams aligned without being swarmed.

Step 3: Defeating the Final Doppelghast Trio 

Once all three beams are locked, the laser system overloads, and the chamber enters a blackout state. The room pulses violet as three Elite Doppelghasts spawn—called “The Veiled.” Each one has a unique power:

• Shifter: Teleports unpredictably and drops clone illusions.

• Shrieker: Emits psychic blasts that disable HUD for 5 seconds.

• Leech: Steals health unless interrupted by explosives.

Defeating them fully charges your canister, completing the Serpent Mound ritual. When the dust settles, the central device opens to reveal a glowing spore core—the key ingredient needed for Donut’s incubation.

Closing Thoughts 

The Serpent Mound is a beautifully bizarre encounter that mixes puzzle-solving with high-stakes combat. It feels like a final test—if you can manipulate light and survive the wrath of elite Doppelghasts, you’re ready for buy bot lobbies bo6 what comes next.
