Subject: Final Fantasy XI – End-game treasure hunt A.M.A.N. Trove (アマン・トローブ) chest-opening strategy, specifically attempting to identify and avoid the lethal Mimic (カスワック / Kasuwak wipe).
1. The Core Premise: The "Nekoya / Nekomata Method" (猫また方式)
The video investigates an urban legend/technique popularized on stream by fellow FFXI creators 猫家 (Nekoya), which Touya and Yusa expanded into the "Nekomata Method" (猫また方式):
A. The Visual Trick (Render Distance / Draw-Culling Glitch)
Config Setup: In FFXI's in-game Graphics / Screen menu under "Other 2" (その他2), set Display Distance (表示距離) to 0 (minimum).
The Approach Run: When entering the battlefield (Horlais Peak, Waughroon Shrine, Balga's Dais, etc.), the player runs forward from the entrance toward the ring of chests.
The Chest Flash (光の順番): As the 10 wooden chests enter the camera's draw radius, their 3D models and lighting kick in, causing them to subtly flicker/flash.
The Mimic Rule: According to the theory, the chest that flashes last is the Mimic.
Resetting: If the flicker sequence is too fast or unclear, the player retreats back to the entrance until the chests despawn from render view, then runs forward again to re-watch the flash.
2. The 224-Run Analysis & The "Moving Mimic" Hypothesis
Touya and Yusa noticed that repeatedly running in and out sometimes caused different chests to flash last. Rather than dismissing it as a rendering glitch, they developed a deeper set of empirical hypotheses:
A. Historical 224-Run Statistical Mapping
They logged the location of the Mimic across 224 past A.M.A.N. Trove runs and ran the frequency distribution through ChatGPT to calculate empirical spawn percentages for each of the 10 outer chest positions.
Findings:
The back-left chest had the highest recorded failure rate (appeared 31 times).
Touya noted an intuitive personal aversion to the front-left and front-center chests (often feeling like high-frequency traps).
Opening Priority: Cross-reference the "last flashing chest" with their statistical chart—avoid the high-risk positions and open the statistically "safe" chests first.
B. The "Sound-Based Mimic Migration" Hypothesis (移動説)
Because the "last flashing chest" shifted during runs, they theorized that the Mimic physically moves between chests when certain sound cues are triggered upon opening a wooden chest:
"Large thud" (大きな音): Mimic moves 1 position.
"Very large thud" (とても大きい音): Mimic moves 2 positions.
"Tremendous thud" (とてもとても大きい音): Mimic moves 3 positions (or player immediately cashes out at the central gold chest).
Movement Pattern: They hypothesized the Mimic traverses in a Z-pattern across the 10 chests, completely skipping the central gold chest (which is the fixed exit/loot chest).
C. Duo Setup & Quality-of-Life
Because in-game frame rates and lighting are dim and fast, Yusa recorded Touya's PC screen using a high-FPS smartphone camera to review slow-motion footage in real-time between chest opens.
They recommended dark BFs like Waughroon Shrine (ワルン) or nighttime weather to make model flashes more distinguishable against the floor.
3. Verification Results (39 Formal Live Runs)
During the video's 39 test runs combining the render flash, statistics, and movement hypotheses:
Outcome Count Notes
Gold Chest Clears / Cash-Outs 11 (~28.2%) Included 3 early exits on "Tremendous thud" (totetote) and 1 instant Rainbow Chest on the 1st attempt.
Kasuwak Wipes / Failures 28 (~71.8%) 7 wiped on the 8th/final chest; 3 wiped on the very 1st chest; 1 out-of-game crash/disconnect.
The 39th Run Blooper: On the final Venus Orb run, an unexpected Windows desktop advertisement pop-up appeared over the game; attempting to click it away caused FFXI to crash/disconnect, immediately ejecting Touya from the battlefield empty-handed.
4. Technical & Reverse-Engineering Reality Check (FFXI Engine & Protocol)
From an FFXI engine and network architecture perspective, here is what is actually happening under the hood:
[FFXI Map Server] [FFXI Client (Direct3D 8)]
│ │
├── (0x0E Spawn Packets: 10 Chests + Gold Chest) ────>│
│ * All chests have identical NPC structure │
│ * Mimic ID / Kasuwak trigger is SERVER-SIDE ONLY │
│ │
│ [Display Distance = 0]
│ * Camera frustum distance sort
│ * Entity draw-call / vertex lighting jitter
│ * "Last flash" = D3D8 culling order artifact
Server-Side Mimic Logic:
A.M.A.N. Trove chest results are strictly server-side authority. The client receives standard NPC spawn packets (0x0E) containing generic entity IDs and model pointers.
The server does not leak which chest holds the Mimic or loot tier in entity spawn data prior to opening (0x01A action / 0x037 interaction packet).
Why Chests "Flash" at Distance 0:
Under Direct3D 8 fixed-function rendering with Display Distance = 0, entities cross the near/far clipping plane and trigger alpha-blending and Gouraud vertex-lighting updates.
The order in which chests render is governed by camera frustum distance sorting and internal entity array indices. Small sub-pixel differences in player position, camera pitch, and floating-point rounding cause different chests to enter the render bucket on different frames.
This explains why running back and forth produced different "last flashing" chests—it is floating-point draw-call sorting jitter, not an in-game monster moving between chests.
Why Their Success Rate Felt Decent (~28%):
In a Mars Orb run, opening all 9–10 chests without hitting a Mimic has an astronomical failure rate (
≈
10
%
≈10% true clear rate).
Their ~28% success was largely achieved because they hedged risk: whenever a "Tremendous thud" (totetote) sounded or a lucky rainbow chest appeared early, they followed the golden rule and immediately took the gold chest rather than pushing to the 8th–9th chest.
Summary Verdict
Entertainment & Flavor: ⭐⭐⭐⭐⭐ (A fun, tense, and creative community investigation featuring great banter between Touya and Yusa).
Viability: Superstitious / Placebo. While the render flash is a real Direct3D8 client artifact, it is not tied to the server's randomized Mimic designation.
Key Advice from the Video: If you try it, don't marathon runs—staring at sub-frame screen flashes with minimum draw distance causes severe eye fatigue and tension!
