BG3 The Counting House Vaults Locations Keys And Loot Guide

The Counting House in Baldur's Gate 3 serves as the heavily guarded financial center of the Lower City, housing immense riches and critical story secrets. Adventurers exploring Act 3 will find that accessing these secure subterranean vaults requires tactical planning, puzzle-solving, and precise key retrieval. Understanding where to locate the specific keys and how to bypass the high-security measures ensures your party walks away with valuable rare equipment.
Gaining Entry and Solving the Primary Vault Code
Before reaching the deepest High Security Vaults, players must gain access through the main bank entry by securing a pass or using stealth. Deep inside, progress is blocked by a massive vault door controlled by a floor pressure puzzle. The code required to open this central door is 1-3-5-6, which can be found in the Head Banker's office on the second floor. Alternatively, players can short-circuit the floor mechanism by applying water and striking it with lightning damage.
Locating the High Security Vault Keys
Each numbered High Security Vault holds distinct treasure, but opening them without lockpicking requires finding individual keys scattered across the city. For instance, High Security Vault Key 1 is held by Captain Grisly, while Vault Key 4 is found inside a locked chest on the second floor of the Water Queen's House. Vault Key 5 is hidden behind a painting in Gortash's safe at Wyrm's Rock Fortress, and Vault Key 6 is located in a chest within the Iron Throne prison. Additional keys can be acquired from prominent NPCs like Nine-Fingers Keene or Rakath Glitterbeard depending on your quest decisions.
High Security Vault Rewards and Notable Loot
Unlocking these secure chambers rewards players with powerful magical gear, substantial gold sums, and key lore documents. Vault 1 contains the Nymph Cloak and Spell Savant Amulet, while Vault 3 features the Long Arm of the Gur heavy crossbow. Vault 4 houses the Trident of the Waves, which creates water surfaces on hit to set up elemental combos. The primary vault, Vault 9, contains the Elegant Studded Leather armor that provides initiative boosts and advantage on stealth checks.
Strategies for Bypassing Locks and Traps
Players who lack specific keys can rely on high Sleight of Hand checks to pick the vault locks. Using rogues equipped with tools and buffs like Guidance or Cat's Grace makes passing the high Difficulty Class checks significantly easier. The surrounding security guards typically do not intervene if you lockpick these inner vaults after clearing out local cultist threats. Utilizing spells like Misty Step or Dimension Door also allows characters to easily bypass physical fences and floor teleporters guarding adjacent safes.
