Vorago

Vorago is a gigantic, rocky and extremely powerful boss monster created by the Anima Mundi that resides in a cave found north of Falador, guarded by its minions, such as the Scopuli and the Stone Devastator. Jagex has stated that Vorago will be the toughest boss in the game, targeted at higher levelled groups of at least five, and drops a variety of unique items, including level 90 Magic armour and weapons, which includes the seismic wand, the seismic singularity, and tectonic armour, it will also rarely drop a pet, a miniature version of one of its Scopuli minions.

The fight with Vorago features a number of different mechanics, having more than 15 different attacks and abilities it can use. Some of these attacks/abilities are having rocks crash into his arena dealing heavy damage onto players who are hit by it (similar to General Graardor's "Graardor Smash!" ability). Vorago is also capable of teleporting around his arena.

The arena Vorago is fought in will change every week of the month, giving the fight a bit of variety and challenges for players who wish to hunt it. He will also be the first boss to feature interactive actions, such as being able to jump on him. He also adapts to the number of players fighting him, so the more players, the greater the difficulty. Up to 50 players can enter Vorago's arena at one time - to even enter the arena you will need to survive a 50,000 damage hit, possibly using damage-negating abilities such as Resonance and Barricade, or potentially splitting the damage among your team as you enter.
