Borderlands 3: Director’s Cut spreads its best secrets across five places: Ava’s Murder Mysteries, the Hemovorous raid entrance, Sanctuary III’s Diamond Armory, the Vault Card menu, and a handful of easily missed collectible and challenge rewards. Start the Murder Mysteries from Ava aboard Sanctuary III, finish the four-case investigation chain, save three Diamond Keys for the Armory, and use the Fallen Heroes Vault Card whenever you play Mayhem Mode. That route gets you the unique Seventh Sense pistol, access to the raid boss Hemovorous the Invincible, exclusive Vault Card gear, and several rewards that never appear in the normal campaign loot pool.
Director’s Cut is not a conventional story DLC with a new planet and a linear campaign. It’s more like a treasure map bolted onto the base game. Some objectives only appear after you interact with the right NPC, while others are buried behind a menu, a three-key door, or an endgame difficulty gate. This guide focuses on those hidden triggers, exact destinations, and the rewards worth spending your time and resources on.
If you’re still tuning your build, the same principle applies as in our weapon ranking guide: a rare gun is only valuable when its damage type and passives match your character. Director’s Cut rewards are strongest when you plan around them instead of grabbing them blindly.
Start Ava’s Murder Mysteries from Sanctuary III
Travel to Sanctuary III and speak with Ava in her room near the central hub. The first quest, Mysteriouslier: Murder on Eschaton Row, becomes available after the relevant campaign progression and Director’s Cut content is installed. If Ava doesn’t offer it, finish the main story and reload Sanctuary; the mission marker can be surprisingly easy to miss when several side quests are active.
The opening case sends you to Eschaton Row in Meridian Metroplex on Promethea. This is an investigation rather than a normal Borderlands firefight. Look for the murder scene, inspect the interactive evidence objects, and follow the ECHO clues until the map advances. The game usually marks the next broad area, but it doesn’t always highlight the exact object you need. If the objective seems frozen, sweep the scene for a body, weapon, blood trail, or glowing clue before leaving.
Enemies appear between investigation beats, so bring a weapon that can clear clustered mobs without wasting your boss ammunition. Shock is useful against Promethea’s common shielded troops, while corrosive damage remains the safer answer for armored targets. Don’t burn all your heavy ammo on the first wave; each case ends with a named encounter or a tougher arena than the opening scene suggests.
The four cases and where each one sends you
The mission chain moves between familiar campaign maps, but each case adds a self-contained crime scene and a new set of evidence prompts. You can complete them in any normal playthrough once they unlock, and the enemies scale to your current level. That makes the chain worth postponing until Mayhem Mode if you want appropriately leveled versions of the unique rewards.
| Investigation | Planet and destination | What to search for | Practical advice |
|---|---|---|---|
| Murder on Eschaton Row | Promethea, Meridian Metroplex | Crime-scene evidence and ECHO clues | Clear the area before inspecting objects |
| Murder in the Wattle Gobbler | Eden-6, Floodmoor Basin | Evidence around the named hunting location | Use corrosive or incendiary weapons for mixed enemy groups |
| Murder on the Heck Hole | Pandora, Konrad’s Hold | Clues scattered through the mine-like arena | Watch ledges and explosive barrels during combat |
| Final Mysteriouslier case | Sanctuary III and the concluding investigation area | Final evidence chain and boss trigger | Bring a complete build, not a leveling loadout |
The final case is the important one because it unlocks the investigation’s concluding boss encounter and the chain’s signature loot. If the mission marker vanishes after a cutscene, return to Ava rather than fast-traveling randomly. Director’s Cut quests often use Sanctuary as a handoff point, and the next objective may not appear until you speak to the quest giver again.

Each Murder Mystery is built around the same loop: inspect the scene, follow a clue trail, survive an ambush, then defeat the case’s named threat. The hidden reward is rarely sitting in a bright red chest at the start. Finish the investigation, watch the dialogue, and open the reward container after the final encounter. Leaving before the quest-complete state can force you to revisit the area and repeat the final interaction.
The headline prize is The Seventh Sense, a unique pistol tied to Ava’s mystery content. Its gimmick is more important than its raw card damage: critical hits create an additional explosive effect, giving the weapon a satisfying payoff when you aim for heads instead of spraying center mass. It performs best on FL4K’s Fade Away builds, Moze’s crit-focused setups, and any character using class skills or artifacts that amplify pistol damage and critical-hit bonuses.
The weapon is fun, but it isn’t a universal replacement for top Mayhem 11 damage dealers. Its effectiveness depends heavily on level, anointment, manufacturer roll, and whether your build can maintain critical hits. Treat it as a precision sidearm for humanoid enemies and exposed weak points, not as your only answer to armored bosses. Save a strong corrosive weapon in the second slot for loaders, heavy armor, and raid encounters.
How to avoid missing evidence
- Walk the perimeter first. Evidence can sit just outside the obvious body or combat zone, especially around corners and low platforms.
- Use the objective marker as a region, not a pinpoint. Search nearby tables, containers, corpses, and interactive props when the marker stops updating.
- Finish every enemy wave. Some clue prompts remain inactive while a named enemy or ambush group is alive.
- Keep the mission tracked. The game’s normal map marker is much more useful when the Murder Mystery is the active quest.
- Return to Ava after the finale. The final hand-in is what properly awards the chain reward and advances the Director’s Cut quest state.
The cases also award experience, cash, Eridium, and normal loot, making them a smart way to level a second Vault Hunter. They’re especially good before your first serious Mayhem push because the objectives teach you to move through existing maps while maintaining combat momentum.

Find Hemovorous the Invincible in Guts of Carnivora
Hemovorous the Invincible is Director’s Cut’s dedicated raid boss. The entrance is in Ascension Bluff on Pandora, inside the same broad Carnivora region used during the campaign. Look for the locked door and interact with it to receive the quest You. Will. Die. (Over and Over.). The entry fee is 500 Eridium per attempt, so farm Eridium before you arrive and don’t spend your entire stash on rerolls or Crazy Earl cosmetics.
Once inside, the arena is a long combat route through the Guts of Carnivora. Hemovorous is a giant Varkid that progresses through armor, shield, and health phases. The boss repeatedly creates smaller Varkids, coats sections of the arena with damaging projectiles, and burrows before reappearing. The safest rhythm is to clear adds immediately, keep moving around the outer edge, and save your strongest burst for the exposed phase after the shell breaks.
Damage types matter. Use corrosive weapons against armored phases, shock against shields, and incendiary or high-base neutral damage once the boss exposes its health bar. Cryo can help control smaller Varkids, but don’t rely on it as your only damage source because the encounter’s most important windows are short. A strong splash build can clear adds quickly, while a single-target weapon handles the exposed boss. Moze’s Iron Bear, Amara’s Phaseflare or Ties That Bind, FL4K’s Fade Away, and Zane’s Clone all have workable paths, but weak builds will feel the Eridium cost quickly.
| Boss phase | Primary danger | Counter strategy | Best tool |
|---|---|---|---|
| Armored shell | Large damage resistance and Varkid adds | Clear minions, then apply corrosive damage | Corrosive launcher or high-rate rifle |
| Shielded phase | Projectile carpets and mobility pressure | Circle the arena and strip the shield with shock | Shock SMG or elemental shotgun |
| Exposed health | Short burst window before the next transition | Spend action skill and critical-hit buffs together | Boss-killer shotgun or sniper |
| Final frenzy | More adds and fewer safe areas | Use Second Wind targets deliberately and keep moving | Ammo-efficient splash weapon |
Hemovorous can drop the Company Man artifact associated with a manufacturer, along with other Director’s Cut loot. Company Man rolls boost a manufacturer’s weapon damage, critical-hit damage, fire rate, and magazine size, but the exact values depend on the roll. Don’t throw away a lower-level one if you’re still building; farm a Mayhem 10 or Mayhem 11 version later when the extra percentages and manufacturer bonuses can support a complete loadout.
For performance and stability before a raid attempt, our low-FPS troubleshooting guide has useful PC basics. Hemovorous fills the screen with particles, acid effects, Varkid bodies, and splash explosions, so a stable 60 frames per second is often more valuable than ultra shadows.
Unlock Sanctuary III’s Diamond Armory
The Diamond Armory is one of Director’s Cut’s easiest secrets to understand and easiest to waste. It sits behind the locked Diamond Door on Sanctuary III’s upper deck. You need three Diamond Keys to open it, and each key is consumed on entry. The room contains weapon displays on the walls, a central loot area, and a limited timer. Once the doors open, move quickly and claim the gear you actually want before the Armory closes.
Diamond Keys come from the Director’s Cut Vault Cards, not from ordinary campaign chests. Activate a Vault Card from the menu, earn Vault Card XP by playing the game, and open Vault Card chests when the progress bar fills. Keys are rare, so don’t spend the first three as soon as you unlock them. Reach Mayhem 10 or Mayhem 11 first if you want the best chance at endgame-level weapons.
The Armory’s displays refresh their selection when you enter, which makes the timing of your run matter. Equip your preferred Vault Hunter, set Mayhem to the level you can comfortably farm, and empty your backpack before opening the door. Prioritize weapons with the right manufacturer, elemental type, and anointment rather than grabbing the first orange item you see. A level-72 world drop with a poor roll can be worse than a well-synergized purple or dedicated legendary.
| Before opening | Why it matters | Recommended move |
|---|---|---|
| Set Mayhem level | Armory gear follows your active difficulty | Use Mayhem 10 or 11 for final farming |
| Clear backpack space | The timer makes inventory sorting painful | Leave at least 20 free slots |
| Save three keys | The door consumes all three at once | Don’t enter for a leveling upgrade |
| Prepare target elements | Random displays may offer several damage types | Know whether your build needs shock, corrosive, or incendiary |
| Bring movement speed | The Armory has a short collection window | Use speed bonuses and loot while moving |
The hidden value of the Diamond Armory is choice density, not guaranteed perfection. It can offer several legendary weapons in one visit, but it doesn’t replace dedicated farming for items such as the Monarch, Plasma Coil, or Re-Volter. Use it when you need a strong upgrade across multiple characters or want to gamble on a manufacturer-specific roll.
Use Vault Cards for exclusive Director’s Cut gear
Vault Cards are Director’s Cut’s long-term reward track. Open the Echo menu, navigate to the Vault Cards section, and activate Fallen Heroes before earning experience. Only the active card receives progress. You can switch cards later, but XP earned while another card is active does not transfer, so choose deliberately when you’re farming.
Fallen Heroes adds exclusive rewards including the Blade Fury pistol, the Guardian Angel shotgun, and the Beskar shield, alongside cosmetics, Eridium, Diamond Keys, and Vault Card-specific weapon skins. The card’s chests can also award keys that unlock the Diamond Armory. Because Vault Card XP is earned during ordinary play, the most efficient approach is to activate it while running Mayhem, proving grounds, slaughter arenas, or a boss farm you already enjoy.
Vault Card chests use a separate reward system, and duplicate drops are normal. Keep opening them rather than waiting for a perfect first roll. The exclusive weapons are most useful when you match their item level and anointment to your final build. A level-72 Guardian Angel can dramatically improve action-skill damage for a setup that benefits from shield-based bonuses, while a poorly matched version may simply occupy a backpack slot.
| Reward | Source | Best use | What to watch for |
|---|---|---|---|
| Blade Fury | Fallen Heroes Vault Card | Close-to-mid-range pistol builds | Element, anointment, and critical synergy |
| Guardian Angel | Fallen Heroes Vault Card | Shield and action-skill damage setups | Don’t judge it without testing the shield interaction |
| Beskar | Fallen Heroes Vault Card | Defensive builds that value damage reduction | Match the shield effect to your survivability plan |
| Diamond Keys | Vault Card chests | Sanctuary III Diamond Armory | Save three for a Mayhem-level run |
| Cosmetics and skins | Vault Card chests | Character customization | Duplicates can still produce useful card currency |
Vault Card XP is not a reason to ignore the campaign’s normal challenges. Complete Crew Challenges, open red chests, and clear side missions while the card is active to stack regular progression with card progress. If you enjoy checklist hunting, our secret-hunt breakdown shows the same useful habit: track every collectible and reward trigger instead of trusting memory.
Best order for every secret reward
The most efficient route depends on your character’s level, but the following order avoids wasting the rarest resources. First, finish the main story and unlock Mayhem Mode. Next, activate Fallen Heroes and complete Ava’s Murder Mysteries. The missions are manageable on a developing build, and The Seventh Sense gives you a precision weapon while you learn which elements your character lacks.
After that, raise your build to Mayhem 10 or 11 using a reliable farm. Revisit Ava’s content if you want stronger quest rewards, then begin Vault Card farming during activities that already produce normal loot. Save every Diamond Key until your build can use level-72 equipment. Finally, attempt Hemovorous with a full elemental loadout, a second-wind plan, and at least 500 Eridium left for another run.
| Player stage | Priority | Secret target | Reason |
|---|---|---|---|
| Story completion | Unlock Director’s Cut systems | Ava’s first mission and Fallen Heroes | Opens the new progression tracks |
| Early endgame | Build stability | Murder Mysteries and Vault Card XP | Provides gear without a raid fee |
| Mayhem 10–11 | Spend rare resources | Diamond Armory | Maximizes the value of three Diamond Keys |
| Raid-ready | Chase premium drops | Hemovorous the Invincible | Tests single-target damage and rewards optimized builds |
Keep an eye on the official Borderlands 3 Director’s Cut Steam page for package details, and check Gearbox’s official Borderlands site for current announcements. The official 2K support hub is also worth bookmarking if Vault Card menus or quest triggers fail to appear after installing the add-on.
Director’s Cut rewards patience more than brute force. Ava’s cases deliver the story-facing secret, Vault Cards steadily feed keys and exclusive gear, the Diamond Armory converts those keys into a high-volume loot gamble, and Hemovorous provides the final skill check. Follow that order, spend Eridium only when your build is ready, and you’ll uncover practically every hidden reward without throwing away the resources that make the endgame hunt worthwhile.
