AC Black Flag Resynced: How to Get the Grand Cayman Secret Chest (The Drunken Puzzle Guide)

You scan the cliff face, grapple gun ready, but there's no grip point. You try parkour across the jagged rocks, nothing. The Grand Cayman secret chest sits tauntingly on a ledge, seemingly impossible to reach. If you're a completionist banging your head against this puzzle, don't worry, the solution isn't a hidden vine or a secret glitch. It's a row of rum cups and a very bad hangover. Here's how to unlock one of the most creative (and frustrating) collectibles in Assassin's Creed Black Flag Resynced.

The 'Unreachable' Chest, Location and Problem

The chest is at coordinates (357, 298) on Grand Cayman island (361, 300) in the Cruz region. It sits on a clifftop ledge with no grapple points, no wall grips, and no climbable terrain, deliberately designed to be inaccessible via standard traversal. This breaks the series' core parkour mechanic; players accustomed to climbing everywhere must rethink the approach.

Grand Cayman has three chests total in the Resynced version, but this is the only one that requires a special solution. The frustration is understandable. You might circle the ledge, try sprinting from a nearby palm tree, or even look for a hidden passage. None of it works. The game has set a puzzle that demands not skill, but roleplay.

Eavesdrop for the Clue, The Drunk Man's Story

The key is an NPC encounter: listen to a drunk man arguing with his wife about drinking five cups of rum and waking up on that exact ledge. No quest marker or log entry points you here, it's pure environmental storytelling.

To find him, head to the Grand Cayman town center. Look near the well just southeast of the tavern entrance, a man in ragged pirate clothing, swaying slightly, speaking loudly to a woman who looks thoroughly unimpressed. He'll insist he drank five cups of rum, passed out, and woke up on that cliff. She'll call him a liar. You, the observant pirate, know better.

This forces players to slow down and act like a pirate investigating a lead, not a simple collectible hunter. It's a rare moment in Black Flag Resynced where the world rewards curiosity over combat. The conversation is easy to miss if you're rushing from marker to marker, which is exactly why it feels so satisfying when you finally catch it.

The Tavern Challenge, Bar Fight, Rum, and Blackout

With the clue in hand, enter the Grand Cayman tavern. Make sure you have at least 125 Reales before entering, each cup costs 25 Reales. Save your game before starting the drinking sequence, as the bar fight can occasionally be buggy. To reliably trigger the brawl, equip your swords before approaching the bartender, then walk directly to the counter and press the interact button. This will usually start the fight; if it doesn't, try shoving a patron first. Disarm a few angry patrons and the room settles.

After the fight (or if none occurs, simply interact with the bartender to order), buy five cups of rum. Consume each cup one by one. Edward will stagger, his vision will blur, and the audio will distort slightly. After the fifth drink, a fade-to-black transition occurs.

Edward awakens on the cliff ledge beside the chest, the game has literally teleported you there. The world wobbles briefly, then steadies. You're standing exactly where the drunk man claimed he woke up. The chest is right in front of you.

This is one of the most memorable collectible puzzles in any Assassin's Creed game. It breaks the fourth wall in a gentle way, acknowledging that sometimes the pirate fantasy isn't about silent kills or synchronizing viewpoints, it's about drinking until you black out and trusting the universe to put you where you need to be.

Reward and Trophy, What You Get

Open the chest to receive the Yoke-Form Vessel art collectible, which can be displayed in Edward's mansion in Great Inagua. More importantly, it unlocks the 'Hungover' trophy/achievement.

For completionists and trophy hunters, this is a must-do, and a memorable story to tell. The Hungover achievement is notable because it can't be earned through standard gameplay; you must actively seek out the drunkard's conversation and the tavern sequence. It's a rare example of an achievement that rewards exploration and roleplay, not just checklist completion. Black Flag Resynced features 224 chests total (154 regular plus 70 special) plus Ultimate Plans, portraits, and paintings, but this one stands out as the cleverest.

Black Flag Resynced, announced by Ubisoft for a July 9, 2026 release on PS5, Xbox Series X|S, and PC, features a massive overhaul of the original game's visuals and mechanics. This puzzle was originally present in the 2013 release of Assassin's Creed IV: Black Flag, and the Resynced version retains it unchanged, a testament to its cleverness. It's a reminder that some of the best game design lives in the margins, hidden in overheard conversations and drunken escapades.

The Lesson of the Drunken Puzzle

The Grand Cayman secret chest is a brilliant puzzle that rewards role-playing over raw skill. It's a reminder that not every obstacle in the Caribbean can be solved with a leap of faith, sometimes you just need to drink heavily, start a bar brawl, and trust the game's most unexpected mechanic. Next time you're stuck on a collectible, remember: listen to the locals, and don't be afraid to get blackout drunk.
