Blood Gems

In-Game Description

A blood gem that fortifies weapons and adds various properties. Blood gems are especially rare blood stones that grow on coldblood.

Blood gems are kneaded into weapons using workshop tools, but only when of matching shape.

Description

Blood Gems are items which can be added to upgrade weapons using the Blood Gem Workshop Tool, found in a chest after defeating Father Gascoigne.

There are a multitude of Blood Gems in Bloodborne. They can be found in fixed locations in addition to random drops from enemies both in the game and in Chalice Dungeons.

The best blood gems can be found in Depth 5 Chalice Dungeons.

A Blood Gem has 4 properties

  • Shape - Determines where the gem can be socketed
  • Primary Affix - The main +Effect of the gem
  • Level - The magnitude of the Primary Affix (1-6)
  • Rank - An overall strength based on primary and secondary strength (1-20)

Notes

  • that the Rating of a gem provides a possible range for the bonus and the ranges overlap between level. As such it is possible for a lower rank gem with a high bonus to provide greater benefit than a higher rated gem with a low bonus.
  • Gems can have up to 3 properties. The primary affix on the gem as well as less powerful, secondary affixes.
  • Cursed gems can have negative properties to offset better-than-usual positive properties
