Vorago

Vorago is a gigantic, rocky, and extremely powerful boss monster created by the Anima Mundi, or as he refers to it, the "earth soul". He has been billed as the toughest boss monster in RuneScape. He is an ancient being that caused chaos in the past, but later defeated, by a powerful weapon known as the maul of omens, prompting him to fall into a slumber. Vorago used his power to destroy the weapon that later reformed. Towards the end of the Fifth Age, he awakened, now friendlier albeit no less powerful.

Vorago is found in the Borehole, a large cave north of Falador, and wishes to test his strength against challengers in order to prepare to defend Gielinor against future threats, such as the gods, should he deem them as such. If challenged, Vorago uses five stages of increasingly high-hitting attacks that change on a weekly basis.

Using the maul of omens to finish him off is a requirement for trimming the completionist cape.

Location
Vorago is located in the cave just north of Falador, east of Doric's hut. The fastest way to get there is by teleporting to the Falador lodestone and running north, past the statue of Saradomin, or simply use Falador Teleport (or, of course, the teletab version).

Starting a fight
There are two distinct ways to start a fight with Vorago: with or without an instance.

With an instance, you can pay 1,000,000 coins per hour, up to a maximum of four hours, to start your own fight, similar to how the God Wars Dungeon instances works. You can set the number of people allowed in the instance (from 1 to 50 players), the minimum combat level allowed to enter the instance, and an optional entry key that other players can use to enter the instance privately.

You could also use the one non-instanced Vorago spawn on each world, which costs nothing but is open to anyone. If Vorago's head is not visible (hence a rocky look on the wall), it means that a team is currently fighting him. If his head can be seen, he is not in a fight.

Once inside the cave, there's a series of chasms that can be jumped across to go to the northern area. Talk to Vorago, and go through all the choices that involve why he is here and challenging him. Once these are done, two coloured messages should show up saying that you are now eligible to fight Vorago.

Upon taking the challenge from Vorago, all nearby players will be given the option if they will want to fight with you or not. After 20 seconds, he unleashes a blast of 50,000 damage which is split between all players who accepted his challenge. Players who do not accept the challenge will not be harmed by the blast. The minimum number of people required to survive the blast normally is four, if each player has over 12,500 lifepoints, although more players are required if at least one player has less. While it is possible for fewer than four players to survive the blast via Warpriest armour, Vorago will not let them in.

Fight overview
Must watch out for Chris Weapons of Mass Destruction they will come out of no where and one hit you

Hard mode
The hard mode option for Vorago is unlocked after a player performs the finishing blow on Vorago with the Maul of Omens on all six of the weekly Vorago rotations (Scopulus, Vitalis, Rock fall, Green Bomb, Teamsplit and The End). You can see which conditions you lack by reading the sign near the entrance to the borehole.

Hard mode is not available in the regular or basic instanced modes. To start up a hard mode instance, the player must click on the cavern entrance (not right click) and hit the third option. You will need 1,000,000 coins to start the instance.

Unlike normal mode, entering a fight in hard mode requires players to survive a hit of 70,000 damage as opposed to 50,000. In hard mode, Vorago is more difficult, and spawns a barrage of red bombs upon entry. In addition, when Vorago does a mage (blue bomb) attack he will always send two pairs of bombs instead of one. He has 10 phases, with all versions of phase 3 there as separate phases. Any special attacks (reflect, red bombs, teamsplit etc.) will not have a warning message. He is also capable of killing summoning familiars when he does his stomp attack.

If killed in hard mode, he has a greatly increased chance of dropping tectonic energy and seismic equipment. The person who has used the maul on him will also receive the title "the Defeater".

Drops
Vorago drops five drop sets upon defeat. Drops will be given to players according to this phase order starting at the north west drop being Phase 1, the north east drop as Phase 2, the middle drop as Phase 3, the south west drop as Phase 4, and lastly the south east drop being Phase 5. The drops are awarded to either the person that did the most damage to Vorago on that phase (DPS), the player that tanked the most bombs on that phase (Bomb tank), or the player that held Vorago's aggression at the end of the phase (Base tank). It is possible for any role, DPS, Base tank, or Bomb tank to get all five drops for a kill.

Charms
Vorago drops 1-5 sets of 5 charms. The following percentages are calculated per set of charms dropped.

Trivia

 * Vorago is an English word, derived from Latin, meaning abyss, chasm, or gulf.
 * A bug allowed players who died at Vorago to duplicate any item that they wanted. The player would die to the blast, and when they came back to their grave, there would be two graves with the same items instead of one. This bug has since been patched.
 * Vorago is loosely based on the living rock creatures (the patriarch in particular), according to Mod Chris L.
 * Hard mode was coded during the developers' lunch breaks.
 * Nobody at Jagex was actually able to defeat Vorago in hard mode through legitimate means before it was released and defeated by players.
 * In hard mode, Vorago has a combined total of 2,250,000 lifepoints, which used to be the highest amount of lifepoints for an attackable monster. This was shattered with the release of the Penance King.
 * After killing Vorago, the Adventurer's Log will say: "I killed a monstrous entity, Vorago." Killing more than one Vorago results in the Adventurer's Log saying: "I killed # monstrous entities of the Earth, the constantly reforming Vorago."
 * When talking to Vorago, he has a yellow colour option showing that he is an NPC, but his yellow dot does not appear when talking to him. When he is challenging a group his colour option will turn from yellow to teal.Vorago (christmas).png]]
 * There is currently a glitch in the first phase where it is possible to have more than one person navigate the cliffs. If everyone navigating the cliffs jumps on Vorago, they will all receive Ancient weapon piece (a) from him.
 * Vorago has the longest death animation out of any boss, lasting for about 15 game ticks.
 * If the player(s) are pushed off during the final phase for Vorago, the player simply gets "pushed off" the cliff and into the water, with the "Instant kill" hitsplat that was originally from the Deathtouched darts appearing. Even though you get pushed off, Vorago does not have any animation when he pushes you off the land. Along with this, Vorago will still try to target the players even though they are already dead, rather than wandering around.
 * Vorago received a new week of rotation on 11 December 2013. This rotation was supposed to appear during that date, but was replaced with the green bomb week due to the phase needing some tweaking. In addition, all players who possessed the "the Defeater" title had it removed. It is possible to regain the title by defeating Vorago in the new rotation.
 * In the final phase, Vorago's information panel will show him with increased Ranged, even though he does not use that combat style.
 * During the 2014 Christmas event, Vorago wore Christmas lights and a Santa Hat.
 * On 8 December 2014, players who defeated Vorago in a team of 7 or lower were notified by a Scopulus that Vorago has changed, and that their previous best has been taken out. On top, players with 'the Defeater' title had been reset. The title can be reobtained by defeating Vorago on the new rotation. Hard mode was also locked until players defeated Vorago in the new rotation.
 * On 12 December 2014, Jagex Moderators gave a "teaser" to the new rotation. However, unlike other teasers, all players could take part in the new rotation, although Vorago was fought in Hard Mode since the current rotation was still Team Split. Players who tried to challenge Vorago in a Jagex Moderator's instance were still given the message if they wanted to challenge him, although saying yes resulted in the message "Only Jagex Moderators can do that today!", even though players who wish to challenge Vorago in Hard Mode are required to have mauled all current rotations before doing so.
