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 group boss monster in RuneScape. He is an ancient being that caused chaos in the past, but was later defeated by a powerful weapon known as the maul of omens, prompting him to fall into a restorative slumber. Vorago used his remaining power to destroy the weapon. 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. Having awoken, he is prepared to defend Gielinor from any future threats he deems worthy of his intervention. One such threat was Tuska, to whom Vorago struck the finishing blow in the conclusion of the Tuska Comes event.

While idle in his cave, Vorago is willing to accept challenges from adventurers to test his strength. He may be fought in groups, who will need to salvage the Maul of Omens from his body and use it to defeat him at the end of the fight. Using the maul of omens to finish off Vorago is a requirement for trimming the completionist cape.

Location
Vorago is located in the Borehole just north of Falador. The closest teleport is the Falador lodestone or Falador Teleport and its tablet version. The portal inside the Max Guild can be attuned to Vorago, arriving right at the entrance to the cave.

Sliske can be seen talking to Vorago about Tuska's defeat. When he spots the player, he will teleport away.

Starting a fight
Every world has the option to fight Vorago using either the world's free encounter or a private instance. Instances cost 1,000,000 coins normally and last up to 1 hour. An instance can hold up to 50 players, and, due to the nature of the fight, respawn speed cannot be customised. Using an instance is the only way to fight Vorago in hard mode.

Inside the cave, there is a series of chasms to traverse to access Vorago. To be eligible to fight Vorago, one will have to speak to him and learn why he is here. Once these are done, two coloured messages should show up saying that you are now eligible to fight Vorago. Learning Vorago's history only needs to be done once.

If Vorago is not currently fighting players for whatever session you are in, his face will be visible. Occasionally, he will be unoccupied but not visible, in which case speaking to him will prompt him to reveal himself. He can be challenged via right click or by going through the dialogue.

When challenged, all eligible players will be given the option to accept the fight. After 20 seconds, Vorago unleashes a blast of 50,000 damage, split evenly between all players who accepted his challenge. Players who do not accept the challenge will not be harmed by the blast. If challenged while he is already preparing to start a fight, the challenger will be notified of this and given the option to join the original fight.

For entry into the fight itself, all players will need to have survived their blast of damage. The minimum number of people required to survive the blast normally is four, if each player has over 12,500 life points. The entry damage flag is based on damage that would have been received, rather than damage actually taken; i.e., even if a player's damage is reduced or blocked in some way, they would have to have survived the unblocked hit to get in. For example, if 5 people accept a challenge, every player will need more than 10,000 life points. Even if one player has 9,000 life points and has damage reduced to 5,000 (thus surviving the blast), all players will fail to get into the fight. When fights are rejected like this, the blast damage is still endured.

Fight overview
Vorago's fight consists of 5 phases, each taking place in a different room, and each having their own mechanics and attacks. Vorago also has a weekly attack that changes based on the current week. He has 6 different specials, changing every Wednesday at 00:00 UTC.

Players cannot teleport out of the arena by any means once the fight has begun. Logging out during the fight is sometimes prevented, usually the beginning of a phase; however, this restriction is not entirely consistent.

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 (Rock fall, Scopulus, Vitalis, 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 use the instance interface and click "Hard Mode".

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's health is still the same, however his attacks are increasingly powerful, 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.

Any special attacks (reflect, red bombs, teamsplit etc.) will not have a warning message. His stomp attack also reflects part of the damage he dealt on the player to the familiar, which can kill them. He has 11 phases, with all versions of phase 3 as separate phases (referred to as phase 3-8) and an additional phase on its phase 5 (phases 10 and 11) where he has to be mauled twice in phase 10 and 11.

If killed in hard mode, he has a greatly increased chance of dropping the ancient summoning stone, tectonic energy and seismic equipment. The person who has used the maul on him during phase 11 will receive the title and also one piece of the Outfit of Omens cosmetic override per hard mode base rotation mauled.

Updates
Vorago received a new weekly special on 11 December 2013: TeamSplit. 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 until they remauled Vorago in hard mode.

On 8 December 2014, "the end" weekly special was introduced and 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. Once again, players' defeater titles were reset. Hard mode was locked until players defeated Vorago in the new rotation. In addition, many mechanics were changed or rebalanced: red bombs used during phase 5 Ceiling Collapse and Scopulus weeks were replaced with teamsplit and purple bombs respectively, Scopulus max hp and damage were significantly increased and they gained the ability to heal, hard mode had some changes such as increased Vitalis orb damage, ceiling debris was changed to deal fixed damage rather than split among people caught in and final phase was changed so when mauling Vorago he jumps back to the arena, changing his attack rotation and requiring a second finishing blow to kill him.

The Legacy Mode update on 14 July, 2014 increased his dismember-smash attack from 4500 to 6000, or 7500 to 10,000 in hard mode.

In late 2014, an easter egg was added to Vorago allowing him to be changed into , a pink variant of Vorago, by using pink dye on him. This only works on World 62, the homeworld of the clan that suggested it. Voraga is the only entity in the game to have pink right click text. The dye will only last for one phase.

Drops
Vorago drops five drop sets upon defeat. For each phase, 3 slots are remembered, for the player who:
 * Dealt the most damage
 * Had Vorago's aggression last
 * Random player who received at least X bombs (exact number unknown)
 * A player is marked as a bomb tank after receiving a certain number of bombs, and a random bomb tank will receive the drop chance for that phase.

This gives a total of 15 drop chances (5 sets of 3). At the end of the fight, a random slot for each phase is chosen, and the player in that slot will receive the drop. It is possible to occupy multiple slots for each phase (e.g. receive the most bombs and dealing the most damage). If the player who occupied a slot that was picked but the player is not present, then the drop will go to a random player who survived the fight.

The location of the drop for each phase is illustrated in the table to the right.

In hard mode, the phase 3 drop slot is given out for phase 8; phase 4 for phase 9; phase 5 for phases 10 and 11 (which are tracked together).

Energy
Tectonic energy is always dropped several times, dropping alongside the main drop for several slots.

Charms
Vorago drops 0–5 sets of charms, 5 charms per drop slot. The following percentages are calculated per set of charms dropped.

Main drop
Every drop slot has the same table of standard loot. The rarities listed are per drop slot.

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 complete the new hard mode through legitimate means before it was released and defeated by players.
 * 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."
 * Vorago is the ninth individual known to have defeated, and the eighth to have killed a god. The others were Jododu Otoku, who killed an unknown god; Bandos, who slew Jododu; Guthix, who slew Skargaroth; Zaros, who killed Loarnab; Zamorak, who defeated Zaros; Armadyl who slew Bandos; Sakirth who killed V and Sliske, who assassinated Guthix.
 * During the 2014 and 2015 Christmas events, Vorago was decorated with lights and wore a Santa hat.
 * Despite not being part of the Godless, Vorago is still labelled under their banner in the scoreboard because he was aligned with them at the time of the third World event Tuska Comes.
