How do you survive the brutal time limits of the ocean biome? A successful chapter 4 walkthrough reincarnated as a dark lord requires mastering the Pearl Maker resource generator, automating your shadow servants efficiently, and navigating the deadly Kraken parallel path choice. Developed by Cuddle Code, Reincarnated as a Dark Lord Before Taking Over the World with Power 999999999 is not your typical idle game. It is a deceptively deep, text-based puzzle RPG where time is always running out. Every click matters, and failure means starting the chapter over.
If you coasted through the early game by importing your demo save and relying on brute force, the beach biome will break you. The prestige mechanics here do not make your character inherently stronger; they only unlock gameplay helpers to speed up your early routing. In this guide, we break down the exact branching paths, mana absorption strategies, and time-saving automation tricks you need to unlock the elusive "Beach, please!" achievement and finally conquer the coastal world.
Essential Prep for Your Chapter 4 Walkthrough Reincarnated as a Dark Lord
Before diving into the coastal waters of Chapter 4, ensure your game is updated past the pivotal Minor Patch 1.0.0.5. This specific update fixed a notorious Godot engine bug where the "Pearl Maker" wasn't working, a glitch that previously ruined countless perfect runs. Additionally, if you are experiencing UI jittering or input lag on the web build, download the Windows version immediately. The tight time limits in this chapter make even a half-second of lag fatal.
Unlike the forest grind in Chapter 2, Chapter 4 introduces a punishing aquatic mechanic that artificially accelerates your time limit. The environment imposes a "Mana Drain 45%" debuff, alongside a looming "Kraken Threat 80%" modifier that ticks up every time you absorb ambient energy. To survive this, and to secure the "Beach, please!" achievement—which currently sits at a rare 0.00% completion rate among casual players—you must leverage your "Chapter Memory actions" wisely.
As the developer has explicitly stated, the prestige system in this game doesn't make your dark lord stronger. Instead, it makes subsequent playthroughs faster by unlocking early gameplay helpers. You will need these "Chapter Memory actions" to instantly bypass the early-stage mana gathering phase, allowing you to focus entirely on the ocean's unique threats right from the first second of the run.
Chapter 4 Walkthrough Reincarnated as a Dark Lord: Optimizing the Pearl Maker
The core puzzle of the beach biome revolves entirely around the "Pearl Maker." This unique resource generator requires a delicate, high-stress balance of mana absorption and minion management. You cannot manually click your way to victory here; the time limits are simply too tight, and manual clicks yield diminishing returns in the coastal zone.
Instead, you must allocate your "shadow servants" to feed the Pearl Maker automatically while you focus your active clicks on developing dark magic. The optimal ratio for this stage of the game is assigning 3 shadow servants to "Mana Gathering" and exactly 2 to "Pearl Cultivation." This specific 3:2 split ensures a steady flow of resources without triggering the ocean biome's over-harvesting penalty.
Crucially, you must keep an eye on your baseline energy. If your reserves drop below 400 mana during the cultivation phase, the Pearl Maker shatters instantly. A shattered generator cannot be repaired within the run's time limit, forcing an immediate respawn. By maintaining that absolute minimum of 400 mana, you prevent the Pearl Maker from shattering and optimize the time limit required to spawn the chapter's boss.
Navigating the Kraken Parallel Path Choice
Midway through the chapter, once the Pearl Maker has generated enough abyssal energy, you are confronted with the "Kraken parallel path choice." This is the primary chokepoint where most players fail. The game presents you with three distinct branching paths, and making the wrong choice results in an immediate, unrecoverable game over.
Here is how the three paths break down:
- Confront the Behemoth: A trap choice. Unless you have somehow glitched the game to retain Chapter 7 stats, your dark lord is too weak. Choosing this results in instant death by crushing.
- Evade through the Trench: The coward's route. While it seems logical for a puzzle RPG with a ticking clock, evasion drains your remaining time by 3 minutes, making it mathematically impossible to reach the final fortress before the run expires.
- Devour the tentacles: The optimal and only viable path.
Thanks to the 1.0.0.5 patch, the parallel paths now calculate their requirements correctly. To survive, you must select "Devour the tentacles." This aggressive path requires you to have accumulated at least 5,000 dark power and actively sacrifices two of your shadow servants. However, surviving this encounter yields the "Kraken Heart"—a mandatory inventory item for unlocking the chapter's true ending and pushing into Chapter 5.
Shadow Servant Automation: Chapter 4 Walkthrough Reincarnated as a Dark Lord
Reincarnated as a Dark Lord Before Taking Over the World with Power 999999999 is deeply deceptive. It masquerades as a standard incremental game, but it is actually a brutally challenging puzzle novel RPG. In Chapter 4, the automation system is your only lifeline against the ticking clock.
The absolute maximum time limit to reach the final coastal fortress is exactly 8 minutes and 33 seconds per run. If you fail to trigger the final event by that exact second, a massive shadowy truck—affectionately known by the community as "Truck-kun"—crashes through the dimension, instantly killing you and resetting your life.
To beat this 8-minute and 33-second timer, manual play is insufficient. You must set your remaining shadow servants to "Auto-Devour" on all tier-1 sea creatures. This bypasses the manual clicking delay entirely. While it seems like a minor optimization, leaving "Auto-Devour" active saves you roughly 45 seconds over the course of the run. That 45-second margin is the exact window needed to process the Kraken Heart and trigger the final boss encounter before Truck-kun ends your run.
FAQ: Chapter 4 Walkthrough Reincarnated as a Dark Lord
Why does my game crash when I reach the Kraken? Ensure you are playing on the downloadable Windows version rather than the web build, and verify your game has updated to Minor Patch 1.0.0.5. This patch explicitly fixed the "Kraken parallel path choice" bug that caused web-build memory leaks.
How do I get the "Beach, please!" achievement? Achieving the "Beach, please!" trophy requires 100% completion in Chapter 4. This means you cannot just beat the chapter once; you must explore every branching path—including the fatal "Confront the Behemoth" and "Evade through the Trench" options—before finally completing a successful run using the "Devour the tentacles" strategy.
Does grinding prestige make Chapter 4 easier? No. As developer Cuddle Code states, the prestige system (Chapter Memories) doesn't make you stronger. It only makes subsequent playthroughs faster by unlocking early gameplay helpers, allowing you to skip the initial mana-gathering phase. You still have to solve the Pearl Maker puzzle and manage your time limit flawlessly.
Can I skip Chapter 1 and 2 if I played the demo? Yes. The full game supports automatic demo save importing. Chapters 1 and 2 in the full release aren't meaningfully different from the demo (aside from a dead face new born dark lord avatar in Chapter 1). You can import your save, jump straight into Chapter 3, and proceed directly to Chapter 4.
