Tomb Prospectors - Hex Research Central

Tomb Prospectors - Hex Research Central provides an in-depth analysis of the mechanics behind Chalice Dungeons in Bloodborne, focusing on the construction of dungeon hexcode, gem pools, and the unique items that can be found within these dungeons.

### Hex Guide The hexcode for dungeons is structured using hexadecimal notation, which simplifies communication with computers compared to decimal counting. Each byte consists of two hexadecimal characters, such as 0A or FF. The first byte of the hexcode indicates the dungeon's area and depth, with values ranging from 0A for Pthumeru 1 to 2A for Loran 4, while the second byte serves as a layout seed, pulling from a pool of dungeon maps. For instance, the dungeon ID on the server is a serial number that can be altered to change the entire dungeon, potentially affecting bloodstains and messages. The join requirements byte determines which chalice is needed to access the dungeon, allowing for the creation of false depth dungeons that display incorrect depth information.

### Gem Pools Gem pools in Chalice Dungeons are determined by the gemCategory system, which categorizes gem effects based on rarity. When a dungeon activates a GemCategory, all effects within that category receive a significant rarity boost. For example, the Pthumeru 5, Loran 5, and Isz 5 dungeons have been extensively farmed, with the gem pool calculations revealing that primary gem effects are chosen before secondary ones. The primary gem effect chances for Pthumeru 5 show a 41.24% chance for Tempering - Physical ATK UP %, while secondary effects are more complex, requiring adjustments based on the primary effect. The total number of gems for Pthumeru 5 is 2075, with a notable 98.91% chance for Native effects.

### Pri+Sec Combinations The combinations of primary and secondary gem effects are crucial for maximizing gem potential. For instance, the primary gem effect "OOE" has a significant presence across various gems, with specific ratios calculated for different dungeons. The data indicates that for gems with non-fixed primaries, the secondary effects must be recalibrated to exclude the primary effect, leading to a more complex adjustment process.

### Discovery The Discovery stat plays a pivotal role in influencing item drops within the dungeons. Higher Discovery values correlate with increased drop rates for rare items, making it essential for players seeking specific loot. The document provides insights into how different farming methods impact the Discovery stat and the overall efficiency of gem farming.

### Dungeon Groups Dungeons are categorized into groups of 10-30, each associated with unique coffin items that can only be looted once. For example, picking up items from one group removes that group from the pool of dungeons that can be created on altars. The Isz glitch complicates this system, as it alters dungeon generation after all items from a group have been collected. The unique items available in various dungeons include the Uncanny Saw Cleaver found in Pthumeru 1 and the Lost Burial Blade in Pthumeru 5, among others. Each dungeon group contains specific items, such as the Blood ATK % Circle gem in Pthumeru 2 and the Communion item that grants maximum vials in Pthumeru 5.

### Unique Items/Dungeon The unique items found in each dungeon highlight the diversity of loot available. For instance, the Uncanny Hunter Axe can be found in Hintertomb 2, while the Lost Kirkhammer is located in Isz 5. Each dungeon has a corresponding list of unique items, including various gems and weapons that enhance gameplay. The Blood Rock, a valuable crafting material, can be found in multiple dungeons, emphasizing its significance in the game.

### Bloodtinge Farming Bloodtinge farming strategies are compared based on the efficiency of obtaining specific gems. The analysis includes calculations of gem chances and the time required to farm them in different dungeons. The data reveals that certain dungeons yield higher chances for specific gem effects, making them more desirable for players focused on optimizing their Bloodtinge builds.

### Multipliers The multipliers applied to dungeons and enemies are influenced by depth and other factors, which significantly affect gameplay. Understanding these multipliers is essential for players aiming to maximize their efficiency in farming and dungeon exploration.

### Important Resources For further exploration of these topics, several resources are provided, including links to the Tomb Prospector Discord, edited dungeon sheets by Trin, and various publications that delve deeper into the mechanics of Bloodborne's Chalice Dungeons. These resources serve as valuable tools for players seeking to enhance their understanding and mastery of the game.

The research conducted by the Tomb Prospector community, particularly by contributors like DrAnger, Trin, and Kazin, has laid a solid foundation for understanding the complexities of Chalice Dungeons, gem farming, and item discovery.
