The Queen Black Dragon is one of the best monsters to kill for money. There is not much variation in the value of her drops, especially compared to bosses whose average profit per kill is largely due to the price of a handful of rare drops. The QBD is fought in four phases, each progressively more difficult than the last. After depleting her health in each of the four phases and activating the four dragonkin artefacts, the QBD will return to her slumber and you will be able to descend from the platform and claim your reward from the dragonkin coffer.
It is highly recommended to have 96 Herblore for access to overloads and super antifire potions – and 92 or 95 Prayer for Soul Split and the combat curses Turmoil, Anguish, and Torment. As the QBD has an extremely high defence level, these, along with level 90 weaponry are highly recommended for the best accuracy. Dragonbane ammunition is also highly recommended, as it provides a flat 30% accuracy bonus while fighting her in addition to 25/40% damage bonus (abilities/auto-attacks respectively), increasing kill speed per hour. Additionally, 96 Summoning for the Pack Yak familiar will greatly increase the number of kills possible between banking. 99 Summoning for a Steel Titan, in tandem with Supreme overloads, Brightfire potions and the Enhanced excalibur, should allow for trips that last as long as the player has familiars and Combination potions.
If Invention is unlocked and the player is using augmented armour, the Dragon Slayer perk (and if on Black Dragon task, Genocidal) can be used to give a 7% (up to 14% on task with Genocidal) boost to damage output to speed up kills significantly. Precise 5 may also be helpful as it increases minimum hits by 10%. Biting 3 and Impatient 3, among other things, may also help speed up kills; it is up to the player to decide if the cost is worth it.
The QBD has no weakness, allowing you to use any combat style. Melee offers the best defence from her attacks but requires you to keep close; Ranged is weak to her melee and neutral to her ranged attacks; Magic is strong against her melee but weak to her ranged attacks.
The standard attacks that the QBD uses are that of melee, ranged, and dragonfire. Her ranged attack is far more accurate and powerful than her melee attack, so average damage from her normal attacks may be reduced by standing within melee distance of her. Her dragonfire attack cannot be fully protected from, and will always deal some amount of typeless damage, typically between 150 and 750. Without any dragonfire protection, this attack can deal up to 2,500 damage.
During the first wave, the only special attack that the QBD may use is the flame wall. When she is preparing this attack, the game chat will read, "The Queen Black Dragon takes a huge breath." This attack may be completely avoided by running through the gap in the wall. However, if using melee, activating an ability to attack the QBD when the flame wall is one square away will allow passage through the flame wall without taking any damage. If improperly timed, 750 damage is dealt instead of the usual 1,500 damage from letting the flame wall pass through you. Once the QBD's health for the first phase has been depleted, she will continuously spit out giant worms until the dragonkin artefact in the centre of the platform is activated.
Upon activating the artefact, the QBD's health bar will refill and the second phase will begin. During this phase, she will use two flame walls instead of one, each roughly 2 seconds apart. These may be avoided in the same manner as before. However, she gains a new attack during this phase; she may summon a tortured soul, which will direct an attack at you. When she is preparing this attack, the game chat will read, "The Queen Black Dragon summons one of its captive, tortured souls." This attack will follow you until it hits you, a worm, or a tortured soul, and will usually deal around 1,000 damage. The easiest way to avoid this attack is to run directly through the soul as it starts speaking. If the damage the soul takes does not kill it, attack it and finish it off. You may choose to not kill any remaining souls, but it may be beneficial to do so as the QBD may draw life from the soul to heal herself, or the soul may re-summon itself to damage you again. Once the QBD's health is depleted once more, activate the southwest artefact to begin the third phase. Keep in mind that standing on the transparent part of the platform for too long will cause a continuous stream of 1,500 damage to be dealt. It is therefore recommended to quickly activate the artefact and immediately run back towards the QBD.
The third phase is very similar to the second phase, though the number of flame walls increases to three. Additionally, she will summon two tortured souls during this phase. Using the same tactic as in the previous wave, luring both of the souls' attacks by running through one of the souls will cause enough damage to the soul to kill it. The other one may be easily killed in two hits. Starting in this phase, the QBD gains the ability to change the consistency of her armour, increasing her defence against either magical or physical attacks while making her more vulnerable against the other. Each of these forms will last for approximately one minute. When she hardens her carapace, the game chat will read, "The Queen Black Dragon hardens her carapace; she is more resistant to physical damage, but more vulnerable to magic." In her hardened form, she will take 25% reduced melee and ranged damage and 25% increased magic damage during this time. The other form she may take is that of crystal, and the game chat will read "The Queen Black Dragon takes on the consistency of crystal; she is more resistant to magic, but weaker to physical damage." This form reduces magic damage by 25% but increases melee and ranged damage by 25%. After either one minute has passed or her health has been depleted, she will return to her normal state. Once her health is depleted, rush to the third artefact, located opposite side of the second one.
The fourth and final phase is by far the most dangerous. The QBD will gain two attacks in addition to the ones listed above. Four tortured souls are summoned in this phase, so it is possible that you may take up to 4,000 damage from just the souls alone, in addition to whatever damage the giant worms and the QBD deal. To avoid the damage from the souls, it is necessary to run diagonally across a summoned soul to avoid taking some damage. This will cause the attacks from 2 of the souls to kill the soul you ran through, but there will still be two souls whose attacks have not yet landed. This can be avoided by running through the nearest soul or giant worm. If all of the souls are not killed, one of them will be teleported to the western-most or eastern-most side of the platform and will begin preparing a "time stop." If this soul is not killed within a few seconds, you will be prevented from doing any sort of action including teleporting for the next several seconds, freezing everyone but the soul that did it and the QBD. Any damage dealt by anything not affected after the time stop ends will dealt immediately in one strike. The second attack the QBD will gain during this phase is the ability to breathe "extremely hot flames." When she is preparing this attack, the game box will read, "The Queen Black Dragon gathers her strength to breathe extremely hot flames." It is not possible to completely avoid damage from this attack, but moving to the west or east side of the platform will reduce the amount of damage taken to 450 three times, dealing a total of 1350 damage and 1950 if in the middle, up to 5850 damage.
Once the QBD's health has been depleted for the fourth time, the artefact to the south may be activated, and the QBD will return to her slumber. Any summoned souls and giant worms will die, and a staircase leading down will appear. You will appear in a room with a dragonkin coffer, from which you may take your loot.The QBD commonly drops Saradomin brews, rocktails and super restore potions, both of which may help extend your stay. With overloads, a pack yak, 92 or 95 Prayer, super antifires, and tier 90 weapons, it is possible to get 20 or more kills per hour, only having to bank once or twice during that time. The fastest way to bank is to use the bank chest in the upgraded workshop of player-owned ports. It may be beneficial to keep the captain's log in your inventory as it provides a method of teleportation in case death is imminent, and it also provides easy access to your gravestone should you die since the log is automatically kept on death.
