The black stone dragon is the final boss of the second elite dungeon, the Dragonkin Laboratory. She is a dragonkin experiment based on gemstone dragons using a type of corruptive black stone.

She was created by Kerapac, who implanted black stones onto a dragon from Vicendithas' old batch. The dragon also had a sister dragon, which Kerapac placed on Anachronia to guard his laboratory. The dialogue during the fight and the dragonkin research diary suggest that the black stone implants allowed Xau-Tak to influence her. After an accident that saw the destruction of another specimen, Kerapac sealed her away in the laboratory, for fear of her extremely uncontrollable nature.

Strategy[edit | edit source]

The black stone dragon can attack with all three combat styles, but primarily uses magic attacks. After she has taken some damage, she will summon four black hands which uses slow but hard-hitting magic attacks while becoming invulnerable herself. Once all four hands are destroyed, she will continue the fight while adding in a few extra special attacks. After taking a certain amount of damage, she will again become invulnerable and fly around the battlefield, leaving slow-moving lines of white fire that can damage the player. Once this is done, she will continue using her default attacks and selective special abilities until she is defeated.

Quests[edit | edit source]

Curse of the Black Stone[edit | edit source]

The following takes place during Curse of the Black Stone.

Curse of the Black Stone quest requires completion of all 3 elite dungeons before or during the quest. As such, the black stone dragon must be faced and defeated at least once; this can be done solo or in a group, as well as on either normal mode or story mode.

Drops[edit | edit source]

One main drop, one secondary drop and one tertiary drop is rolled after the black stone dragon is defeated. The size of the group that went through the elite dungeon determines which drop table is used. There is a chance of additionally receiving a drop from the rare drop table.

Main drops (Solo)[edit | edit source]

Average amount of Draconic energy per kill is 10.87 (13.044 including double chance) with a value of 7,013,171.82 (8,415,806.18).

  1. ^ Amount dropped in Story mode is reduced to 500.
  2. ^ Inert black stone crystal has a base drop rate of 1/300, with a threshold of 60. Example: If a player were to have 101 group and 144 solo (combined 245), it would be 4 thresholds for solo, 1 threshold for duo and 0 thresholds for trio. Rolled for before the rest of the main drop table and replaces that drop if obtained.[3][4][5][6]

Main drops (Duo)[edit | edit source]

Average amount of Draconic energy per kill is 3.885 (4.662 including double chance) with a value of 2,506,547.61 (3,007,857.13).

  1. ^ Amount dropped in Story mode is reduced to 500.
  2. ^ Inert black stone crystal has a base drop rate of 1/1000, with a threshold of 200. Example: If a player were to have 101 group and 144 solo (combined 245), it would be 4 thresholds for solo, 1 threshold for duo and 0 thresholds for trio. Rolled for before the rest of the main drop table and replaces that drop if obtained.[3][4][5][6]

Main drops (Trio)[edit | edit source]

Average amount of Draconic energy per kill is 0.784 (0.9408 including double chance) with a value of 505,825.82 (606,990.99).

  1. ^ Amount dropped in Story mode is reduced to 500.
  2. ^ Inert black stone crystal has a base drop rate of 1/1500, with a threshold of 300. Example: If a player were to have 101 group and 144 solo (combined 245), it would be 4 thresholds for solo, 1 threshold for duo and 0 thresholds for trio. Rolled for before the rest of the main drop table and replaces that drop if obtained.[3][4][5][6]

Secondary drops[edit | edit source]

Exactly one of these drops per kill.

Tertiary drop[edit | edit source]

The following table has a 1/25 chance to get rolled on for boss monsters and mini-bosses, and a 1/50 chance for other monsters when holding a Lucky charm (Dragonkin Laboratory).[7]

  1. ^ A mysterious egg is significantly more likely to drop when the player has the Mysterious perk on one of their equipped items.[8]

If the above table is not rolled, a reward from the following table is given:

Rare drop table[edit | edit source]

This monster has access to the rare drop table.
Luck-enhancing items are not required to access the table, but they will increase the chance of accessing the rare drop table and may also improve the loot received from it.

    • The black stone dragon's flaming spiral attack will no longer damage players after she is defeated.

    • Both God Wars Dungeon 2 and Elite Dungeon bosses now award more Reaper points and Slayer XP when killed in challenge/hard mode.

    • Prevented a crash that occurred when the Black Stone Dragon was defeated in group mode, but the group wasn't aligned to the Dragonkin Laboratory.

Music unlocked[edit | edit source]

Trivia[edit | edit source]

  • The existence of the black stone dragon was first hinted at on release of the first elite dungeon, Temple of Aminishi. After releasing Seiryu from Xau-Tak's control, his dialogue refers to "another sharing his torment...under the obliterated crust of Forinthry."
  • The dragonkin research refers to her as "Kreath Takla Draekun", and while "Kreath" and "Draekun" are confirmed to translate to "Black" and "Dragon" respectively, it is still unconfirmed if the entire name is a literal translation.
  • The black stone dragon was referred to as male in one of the Patch Notes despite being female.
