Ancient Cavern

The Ancient Cavern is an area reached from the whirlpool near Otto Godblessed's house, which was released on 3 July 2007. A player must dive into the whirlpool to enter the cavern, which contains many high-level monsters, including a high level metal dragon, the mithril dragon.

Fighting these dragons is one of the two possible methods of obtaining a dragon full helm without having to purchase it from another player. The dragons occasionally drop the helm directly. They also occasionally drop chewed bones. Lighting a pyre ship made with chewed bones releases the spirit of a departed barbarian, who occasionally rewards the player with this rare piece of armour.

The cavern is in a members-only area and can only be accessed after the player has completed the first Firemaking activity in Barbarian Training, which requires level 35 Firemaking. After that, the player must ask about making pyre ships, and then will be granted access to the dungeon in order to fulfill the objectives required to make them. (Barbarian training is also required to be able to make pyre ships.) If a player dives into the whirlpool before completing these tasks, they will be swept away, losing a small amount of their life points, eventually washing up on the shore near Hadley's house.

Players cannot leave the cavern via the whirlpool. Instead, they may leave by riding on one of two aged logs that can be found near the waterfiends. The logs are floating on the water, as shown on the map, and have examine text of "A log jammed by the current, perhaps rideable."

A fairy ring, also located near the waterfiends at the western end of the lower level, can be restored for use by players who can use the rings. With a spade (toolbelt works) and 5 bittercap mushrooms in their inventory, the player can restore the ring by planting the mushrooms on the "Enchanted land" spot near the centre of the ring. After it is restored, players can use it to quickly teleport in and out of the cave. The fairy ring code is.

The Ancient Cavern is "far too damp" to use a cannon.

A follower can't be taken into Ancient Cavern by the whirlpool, but instead, one can use the fairy ring to do so. This is especially useful for bringing a clan avatar for the 6% experience boost.

Introduction
The Ancient Cavern is one of the more dangerous dungeons in RuneScape. All who enter the area should be prepared to face dragons with long-range attacks, and high-level monsters that can attack using more than one combat style. None of the monsters in the Ancient Cavern, except skeleton heavy, can be poisoned.

To access the dungeon the player must have learned about funeral pyre burning, in Barbarian Training from Otto Godblessed. To enter the dungeon, the player must jump into the whirlpool off the jetty on the northern shore of the Baxtorian Falls lake. Players cannot jump into the whirlpool with a Summoning familiar. Upon entering the cavern, the player appears on a small platform with stairs to the lower level and can see a mithril dragon off in the distance in another part of the upper level. No creatures on the lower level are visible until the player descends the stairs, so the platform cannot be used for making ranged or magic attacks. The biggest dangers in the cavern are the brutal green dragons on the lower level and the mithril dragons on the upper level. Players should be prepared to be attacked by a brutal green dragon as soon as they descend the stairs to the lower level, and it can use melee, magic, and dragonfire breath. Inexperienced players can be killed descending the steps if not prepared for dragonfire breath attacks. The Protect from Magic Prayer can help reduce damage as well. The lower level also has many other monsters in various places.

The caves are dangerous, and one should be well prepared before entering the cavern. It is recommended to pack decent combat gear; an anti-dragon shield (or dragonfire shield), antifire (or super antifire) potions, super sets, an emergency (one-click) teleport, and high-healing food. A ring of life may occasionally save players in mortal danger, but the high-hitting monsters have the potential to outright devour players before the ring can activate.

Location and travel
The whirlpool entrance to the Ancient Cavern is south of the Barbarian Outpost near Baxtorian Falls. Players can get there by walking west from Seers' Village, north from East Ardougne, or east from the Tree Gnome Stronghold. (From the stronghold, players with level 37 Agility can take the shortcut northeast of the Grand Tree; otherwise, the more round-about route through the stronghold's southern gate is necessary.)

Some teleports can be used to get near the whirlpool:
 * A games necklace can teleport to the Barbarian Outpost. This is quickest way to get to the whirlpool, as it is just south of the Outpost.
 * A combat bracelet can teleport to the Ranging Guild, which is east of Baxtorian Falls.
 * Barbarian Teleport from the Lunar Spellbook. Teleporting between barbarian outpost and Lunar Isle provides quick banking during slayer tasks.
 * A plain of mud sphere can teleport one near the Fishing Guild, which is south-east of Baxtorian Falls.
 * A skills necklace can teleport to the Fishing Guild, which is south-east of Baxtorian Falls.
 * Players with level 37 Agility can use the gnome gliders or spirit trees to travel to the Tree Gnome Stronghold and then use the shortcut north of the Grand Tree to get to the Baxtorian Falls lake.

Two teleports can be used to directly enter the dungeon:
 * Fairy ring code, which will teleport near the north-western most waterfiends, once it is repaired as described earlier.
 * The ferocious ring, which is a drop from the creatures in Kuradal's Dungeon, can teleport the player to Kuradal (Note: you can only attack the monsters in the dungeon if they are your current Slayer assignment assigned by Kuradal or Morvran.)

Map of the cavern
The upper level is split into separate sections. The small northern section is where the player appears after jumping in the whirlpool on the surface world. Stairs #1 connects this section to the lower level. The main part of the upper level can be reached from stairs #2 while the dragon forge chamber can be reached from stairs #3. Stairs #3, the 'rough-hewn steps', once were too slippery to climb until after the While Guthix Sleeps quest was finished, but now can be climbed by anyone in the cavern, giving access to the Slayer Master Kuradal, as well as the entrance to her slayer dungeon. The dragon forge and the mithril door at #4 are discussed below.

"Skeletons" on the map are skeleton warlords. "Barbarians" are confused barbarians. "Spirits" are barbarian spirits.

The location of the monsters on the map is approximate, as they wander about. For example, a skeleton warlord occasionally can be found with the waterfiends.

A total of 12 mithril ore rocks can be found on the upper level. None are safe to mine, as mithril dragons roam throughout the upper level. One Skeleton warlord is also present on this level, in the south-east area.

Fairy ring can be found at the western edge of the lower level. It must be restored before it can be used, as explained earlier in this article.

Rummaging skeletons
Lower-level players sometimes visit the cavern in search of bones to make pyre ships, as learned in Barbarian Training. Since mithril dragons, the source of chewed bones, are extremely dangerous to lower-level players, the player should concentrate on finding mangled bones instead. These bones can be obtained by rummaging the barbarian skeletons that are lying on the ground. There is one such skeleton just south of the safespot described above. Be aware that rummaging a skeleton may result in the player taking 2000 or more damage.

There are, in total, three skeletons that are rummageable throughout the caverns. Please note that there are none on the top floor. This is where you can find them:
 * One is near a skeleton thug. Use Protect/Deflect Magic as there are some brutal green dragons nearby.
 * One is near the waterfiends near the staircases. Use of Protect/Deflect magic then Protect/Deflect range should be used.
 * One is right between the confused and lost barbarians. Players should use Protect/Deflect Magic as the passage the confused barbarian is in is not safe, and there are several brutal green dragons near it.

Messages and rewards when rummaging skeletons: "You rummage in the sharp, slimy pile of bones in search of something useful..."
 * "...you find something and stow it in your pack." (Or, if the inventory is full, "...you find something, but it drops to the floor."). Items that may be found include:
 * Bones
 * Mangled bones
 * Ancient page for the My notes book.
 * "...the bones object." One of the following barbarian skeletons will appear and attack (Protect from Melee is effective against them):
 * Skeleton heavy (level 128)
 * Skeleton hero (level 106)
 * "...but there's nothing remotely valuable." Nothing was found.

When rummaged, the pile of bones disappear. It respawns after about two minutes. If a skeleton heavy or hero appears when it was rummaged, the heavy or hero disappears when the pile of bones respawns.

The dragon forge and mithril door
Beyond Kuradal is a long cave, ending in a chamber, the dragon forge, that contains a large basin, 3 dragon heads made out of metal, and many anvils. There are channels in the side of the basin and marks in the floor where lava flows from the mouths of the dragons and into the basin, then flows out again and runs along the floor, out of the room.

After the completion of the quest, While Guthix Sleeps, it is possible to unlock the mithril door on the upper level using a Dragonkin key. This key is made by fusing together the strange key teeth with the strange key loop, items found during the quest. The player can get the key fused by using either piece on a mithril dragon while have the other piece of the key in inventory. Be aware that some player regard this activity as being hazardous while the mithril dragons are aggressive, although it is possible to fuse the key on a mithril dragon that is attacking. The key cannot be fused on a mithril dragon, however, while the player is being attacked by a different mithril dragon.



The Dragonkin key unlocks the mithril door. The key disappears when this occurs, and the door thereafter remains unlocked. The player can then enter the mithril key chamber. Inside the mithril door are three hanging dragon heads and a giant orb in the centre. The player must click on each head to light it, with Fire Wave spells (this requires air and fire runes) which will cause them to have fire to appear in their mouths and to slide towards the orb in the centre.

Once the orb in the chamber is lit, the forge fills with molten lava and can now be used. The player can use a blast fusion hammer, purchasable from the Blast Furnace Foreman at the Blast Furnace in Keldagrim for 1,000,000 coins, to fuse together the three parts of the dragon platebody with 92 Smithing (the Assist system can NOT be used) or change between the three versions of dragonfire shield. Using the Blast fusion hammer here will cause it to disintergrate.

Players who try to use a metal bar on one of the anvils get the message, "The anvil resists the metal pushing it away." This also occurs with elemental bars, even though they are not classified as metal.

If a player who has lit the forge and a player who has not are in the same area they will not be able to see each other, so players wishing to light the forge will sacrifice seeing most players at Kuradal as most players do not light the forge.

After partial of completion of Hero's Welcome, a new door appears in the same area as the dragon forge, leading to the Dragonkin Lair.

Monsters
Confused barbarians and skeleton warlords, both of which wander the lower level, are opponents that are not that difficult. Spirits are tougher, hitting harder and more often. All three, however, only use melee, so the protection from melee prayer is effective against them. They may or may not be immune to the effects of poison.

Waterfiends are much more of a challenge. They use magic and ranged attacks, and their magic attacks can be very powerful. They are weak to bolts and immune against poison.

Brutal green dragons are tougher still, as they attack with melee, magic, and dragonfire breath. Like the waterfiends, these monsters are immune to poison.

Mithril dragons are very formidable. They attack using melee, magic, range, and dragonfire breath, and are weak to earth spells. Like waterfiends and brutal green dragons, mithril dragons are immune to all types of poison. The mithril dragons can hit high, so make sure to watch out for this. Even with good equipment and high defence, be aware that death is a possibility at any time.

On 8 December 2009, Jagex updated the ancient cavern with a new area housing the slayer master Kuradal and a variety of slayer monsters.

These monsters are: After the Harbingers of Tuska update of 3 December 2013, an additional chamber was added to Kuradal's Dungeon, containing a new slayer monster
 * Greater demons, level 82
 * Gargoyles, level 93
 * Blue dragons, level 74
 * Hellhounds, level 92
 * Abyssal demons, level 98
 * Dark Beasts, level 105
 * Iron dragons, level 98
 * Steel dragons, level 100
 * Airut, level 122

Music unlocked

Trivia

 * When the cavern was released, both the mithril door and dragon forge were inaccessible, although the steps to the forge and the door still existed, although they couldn't be used, as the door was locked and the steps were too slippery. On 28 October 2008 Jagex released the Swept Away quest and the 2008 Halloween event. At the bottom of the news article announcing this update, a message stated that "A distant rumble had recently been heard just north of Baxtorian Waterfall...". This allowed access to the (unlit) dragon forge, as one of the many teasers to While Guthix Sleeps.
