Legion Boss Guide: Xavius

Background

Once a powerful mage, and a councilor to Queen Azshara, Xavius forged a pact with Sargeras to enable the Legion's first invasion of Azeroth. Cursed and tormented in the wake of that defeat, Xavius plots vengeance against the world from within the Rift of Aln. Those who venture into the Nightmare will face the full extent of his power, and his true form - a grotesque and distended monstrosity.

Overview

This fight is taking place on a circle platform surrounded by a mist.
It is divided in 3 phases in which each phase has its own certain mechanics that does dmg and gives you corruption.

During the fight you will get corruption on you (A bar from 0-100).
After certain amount of corruption, you see things that will harm you (no one else will see it).
After 100 corruption, your dps/heal will be increased by 150% for 20 seconds, then you will get Mind Controlled and others have to kill you.

During the fight you will also enter a Dream phase in which you will be on the same platform and attacking boss/mobs.

You are in the dream world for a reason. Handle mechanics that gives corruption and burst out all healing and dps that you can since it resets when you come out from the dream phase.

The fight is about balancing your corruption by avoiding most things in the real world and handle them in the dream world because your corruption will be reset when you come out from the dream world.

In the last phase, no one can enter the Dream World which means that you will get more corruption on you since it will not reset. This phase is all about nuking the boss as fast as possible and some players will get 100% corruption which means that they will also get 150% increased dmg/heal for 20 sec. But also means that they need to be killed when mind controlled.

This fight is divided in:
- 3 phases (Phase 1: 100%, Phase 2: 65%, Phase 3: 30%)
- 2 Dreams (Dream 1: 95%, Dream 2: 60%)
- Your Corruption Bar (0-100 Corruption)
- Xavius Energy bar (add spawns at every 100 energy)

Detailed mechanics and Positioning

CORRUPTION

Many of Xavius abilities does Corruption on the players.
You will have a corruption bar (0-100) during the fight.
Only you can see and take dmg from following, when you reach certain amount of corruption: 

33< Corruption
An add (Dread Abomination) will spawn from the mist and smash his limbs on the encounter platform (Big circles will spawn on the ground before impact).

66< Corruption
Shadow balls will land on random locations on the platform (small circles will spawn on the ground before impact). Getting hit does damage and adds 5 extra corruption.

100 Corruption
You will get 150% extra damage and healing boost for 20 seconds.
Then you will mind controlled and attack allies until killed.

This will most likely happen to some players at the end of the fight.

Other players need to kill Mind controlled players.
