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.
Black Gem Tiers
Black Gem has 3 different tiers. You can increase tiers by processing with other enhancement materials.
Black Gem Fragment âž”
Black Gem âž”
Concentrated 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:Â 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. (Gather elk corpses using a Fluid Collector, Butcher Knife, or Tanning Knife with 1,500 Gathering Mastery.)
Hunting Byproduct = Black Gem Fragment
Wildspark is a hunting byproduct that can be obtained at a fixed probability when butchering hunting mobs.
- Requires Hunting Mastery of 250+
- You can obtain Wildspark as loot upon defeating [King of the Grass Rhinos] Rawr-rawr and other hunting mobs.
- Collect 10 Wildsparks and visit NPC Liana in each major city to exchange them for the items below.
Exchange List:
- Wildspark x10 = 900 Contribution EXP + Hunting EXP x30
- Wildspark x10 =
Black Gem Fragment x5
- Wildspark x10 =
Spirit Pouch of Ferocious Beast
Wildspark has the best drop rate from Shadow Wolves at Narcion. (400+ per hr.)

TRI (III) → TET (IV) | 20 | 135 | 1100 |
TET (IV) → PEN (V) | 65 | 330 | 2200 |
NOTE: The enhancement chance of a Life Mastery Accessory is NOT influenced by a failstack or Valks’ Cry.
When a Life Mastery Accessory fails enhancement, the accessory is destroyed and the Black Gem is lost. (Preonne are excluded from this rule. Instead they downgrade upon failure, unless Cron Stones are used.)
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.
