Black Gems were introduced into BDO with the Life Mastery patch on 9-4-19. They are used to enhance Life Mastery Accessories and Life Mastery Clothes. Note that Life Mastery Tools are enhanced by Black Stone and not Black Gems.

Black Gems are unique because they don’t use the traditional Failstack system.

 

BDO Black Gem Tiers

Black Gem has 3 different tiers after processing with other materials.

Black Gem FragmentBlack Gem Fragment ➔ Black GemBlack Gem ➔Concentrated Magical Black GemConcentrated Magical Black Gem

Black Gem Fragment (T1)

Black Gem Fragments are used to create Black Gems and then upgraded again to Concentrated Magical Black Gems.

Obtain Black Gem Fragment:

  • Gathering blood, meat, and hide give the best drop rates for Black Gem Fragments. The best location to obtain Black Gem Fragments is Behr, hunting Elk.
  • Other Gathering at a lower rate:
    • Hoe Gathering
    • Mining
    • Barehanded Gathering (excludes Golem gathering)
    • Tree Sap Collecting
    • Lumbering
    • Hunting with a Matchlock/Sniper Rifle and then butchering will provide Black Gem Fragments as well.

NOTE: The rates of fragments from chopping/sapping trees and mining is lower than butchering/bleeding animals or gathering herbs.

According to bdolytics.com the elk located south of Behr can be gathered for about 150 Black Gem Fragments per hour..

Safer Enhancement:

  • Optionally, Cron Stones can safeguard a Life Mastery Accessory from being destroyed from failed enhancement.
  • If the enhancement fails, there is a 60% chance that the enhancement level will be maintained and a 40% chance that the enhancement level will decrease.
