The short version
30-second read- The lair itself is not Wilderness. Nobody can attack you inside and normal teleports work, unless you picked up a teleblock on the way.
- Stay in melee distance. At range he never melees, so half his attacks become special breaths instead of a third.
- Antifire plus the shield takes regular fire to 0. Special breaths still hit up to 10, and their freeze or stat drain is when fights go wrong.
- Carry cheap gear through the Wilderness. The walk passes level 42 Wilderness, so keep expensive switches at home.
Overview: King Black Dragon at a Glance
The King Black Dragon, or KBD, is a level 276 three-headed dragon with 240 Hitpoints. His lair is reached through the deep Wilderness, but the lair itself is not Wilderness: nobody can attack you inside and normal teleports work.
He stabs for up to 25 when you stand next to him and breathes four kinds of dragonfire. Regular fire hits up to 65 with no protection. The toxic, shocking and icy breaths hit up to 50 and can poison you, drain all your stats by 2, or freeze you for 10 ticks. An anti-dragon shield plus an antifire potion takes regular fire to 0 and the special breaths down to 10.
The KBD is a separate boss from the level 227 black dragons in Taverley Dungeon, though he counts toward a black dragon Slayer task, except one given by Krystilia.

Access Requirements
There are no strict requirements to fight the KBD. The one thing you need in practice is an anti-dragon shield, which takes partial completion of Dragon Slayer I.
The OSRS Wiki suggests 80 Attack and Strength, 70 Hitpoints and 70 Prayer for Piety on melee, or 80 Ranged and 74 Prayer for Rigour on ranged.
KBD Lair Location and Route
The entrance is a ladder inside a fenced area at the western side of the Lava Maze. Down the ladder, pull the lever surrounded by poisonous spiders to enter the lair.
| Route | Steps | Needs |
|---|---|---|
| Burning amulet | Teleport to the Lava Maze, run west then north along the fence, through the gate, down the ladder | Burning amulet |
| House obelisk | Set your house obelisk to level 44, teleport, run south-east to the gate and ladder | Hard Wilderness Diary |
| Ghorrock Teleport | Teleport to the Frozen Waste Plateau, run south-east to the gate and ladder | Desert Treasure I |
| Games necklace and obelisk | Corporeal Beast teleport, run to the obelisk, pick level 44, run south-east | Hard Wilderness Diary |
| Waka canoe | Canoe from Edgeville to the Wilderness pond (level 35), then run north along the fence | 57 Woodcutting and an axe |
The walk crosses roughly level 42 Wilderness, which player killers patrol. Only bring what you can afford to lose: you keep three items on death (four with Protect Item, none if skulled). If you get teleblocked on the way, the lair lever will not let you escape.
King Black Dragon Strategy
- 1
Sip antifire and drink your combat potion before you pull the lever.
He is aggressive and can breathe on you from a distance as soon as you enter.
- 2
Walk into melee distance and turn on Protect from Melee.
It blocks his stab completely.
- 3
Stay in melee distance.
There he picks melee 1/3 of the time, regular fire 1/3 and a special breath 1/3. At range he never melees, so half his attacks become special breaths.
- 4
Let the shield and antifire handle the fire.
With both, regular fire does nothing and special breaths hit up to 10.
- 5
Eat when you are low after a special breath; a freeze or a stat drain is the moment fights go wrong.
- 6
Bank or teleport when supplies run low.
The lair is not Wilderness, so teleporting out is safe.
With a 5-tick weapon such as a twisted bow, dragon hunter crossbow or Osmumten's fang, you can walk under him after each attack. He attacks every 4 ticks, so this keeps the exchange at one attack each and cuts your damage taken by about 20%.
KBD Gear and Weaknesses
| Check | Value |
|---|---|
| Prayers for its own attacks | Protect from Melee |
| Its Defence level | 240 |
| Its Magic level | 240 |
| Lowest defence | Stab and heavy ranged ammunition (40) |
| Elemental weakness | 50% to water spells |
| Monster attributes | Dragon, fiery |
- He counts as a dragon, so dragonbane weapons like the dragon hunter lance and dragon hunter crossbow get their bonus.
- Stab is his weakest melee style, and crossbow bolts are his weakest ranged ammunition.
- He has a 50% elemental weakness to water spells.
- Keep the anti-dragon shield equipped. A twisted bow or other two-handed weapon means no shield, so you have to pray Protect from Magic instead.
KBD Inventory
- Anti-dragon shield, worn.
- Antifire potion, or an extended version for longer trips.
- Prayer potions or super restores for Protect from Melee.
- A super combat or ranging potion.
- Food for the rest of your slots; the special breaths are what drain it.
- A burning amulet to get there, and a normal teleport to leave the lair.
- Optional bonecrusher necklace: buried dragon bones restore 4 prayer points each.
- Optional rune pouch with runes for thralls.

Where King Black Dragon Sits in Progression
KBD is a common first dragon boss. Vorkath uses the same antifire-and-shield setup with harder specials after Dragon Slayer II, and Zulrah is where gear switching starts.
KBD Drops
Every kill drops dragon bones and 2 black dragonhide. The Wilderness Diary does not note his bones, so a bonecrusher necklace or regular banking is how you deal with them.
| Drop | Rate |
|---|---|
| Dragon bones | Always |
| Black dragonhide (2) | Always |
| KBD heads | 1/128 |
| Dragon med helm | 1/128 |
| Elite clue scroll | 1/450 |
| Dragon pickaxe | 1/1000 |
| Prince Black Dragon (pet) | 1/3000 |
| Draconic visage | 1/5000 |
Combat Achievements
Check the current King Black Dragon tasks in the in-game Combat Achievements menu; the Combat Achievements guide covers working through the tiers.
Ironman Notes
Slayer masters who assign the King Black Dragon as a boss task: Konar, Nieve and Duradel. Each kill is 258 Slayer XP, and he also counts for black dragon tasks unless Krystilia gave them.
Irons use the KBD for the dragon pickaxe chance and the black dragonhide toward Crafting. Since the lair itself is safe from PKers, the main risk is the short Wilderness walk, so bring cheap gear in and keep the expensive switches at home.
Common Mistakes and Death Causes
- Forgetting the anti-dragon shield, or swapping to a two-handed weapon without switching to Protect from Magic.
- Letting antifire run out mid-kill.
- Fighting at range on a melee setup, which raises special breaths from a third of his attacks to half.
- Carrying expensive gear through level 42 Wilderness.
- Ignoring the shocking breath's stat drain and fighting on with lowered stats.
- Assuming the lever is an escape after being teleblocked.
FAQ
Is the King Black Dragon the same as a black dragon?
No. Black dragons are level 227 monsters found in places like Taverley Dungeon, the Evil Chicken's Lair and the Lava Maze Dungeon, with a level 247 version in the Wilderness Slayer Cave. The KBD is a separate level 276 boss, though he counts toward most black dragon Slayer tasks.
Can you teleport out of the KBD lair?
Yes. The lair is not part of the Wilderness, so normal teleports work and other players cannot attack you there. The exception is a teleblock picked up on the way in.
What do I need to fight King Black Dragon?
No quest or skill requirement. In practice you need an anti-dragon shield (partial Dragon Slayer I), an antifire potion, prayer potions for Protect from Melee, and a route through the Wilderness such as a burning amulet.
Which protection prayer should I use at King Black Dragon?
Protect from Melee while standing in melee distance, with your anti-dragon shield and antifire covering the dragonfire. If you use a two-handed weapon and can't hold the shield, pray Protect from Magic instead.
How hard does King Black Dragon hit?
Up to 25 with melee, 65 with regular dragonfire and 50 with the special breaths when unprotected. A shield plus antifire cuts regular fire to 0 and the special breaths to 10. He has 240 Hitpoints.
Where is King Black Dragon and how do I get there?
In the King Black Dragon Lair, reached by a ladder in the western Lava Maze and a lever below it. A burning amulet's Lava Maze teleport is the fastest route; the walk crosses about level 42 Wilderness.
Is King Black Dragon worth doing?
As a first dragon boss and for the dragon pickaxe, KBD heads or pet, yes. As pure money, his steady drops are mostly bones and hides, so check the wiki's live table against other bosses.
What kills people at King Black Dragon?
Player killers on the walk in, and fighting without the anti-dragon shield and antifire combination. Inside the lair, it is usually letting HP sit low while special breaths keep landing.

Bottom Line
KBD comes down to four things: an anti-dragon shield, antifire, Protect from Melee in melee distance, and cheap gear for the Wilderness walk. With all four, his regular fire does nothing and his special breaths hit 10 at most.
If you want the kill count, a KBD head or the pet hunt done without the Wilderness trips, our KBD service is done by hand, with no automation. Otherwise the bosses list has the full index.
