User:Serillian/Prophet Sin'gurath

Prophet Sin'gurath is the first boss encounter in the Depths of Nightmare.

Background
Over the centuries, Prophet Sin'gurath has made several prophecies about Azeroth, many of which has been proven true. These prophecies range from the Titan's arrival to the eventual lost of immortality of the Aspects. Recently, he has made another prophecy, much more dreadful than before.

Abilities
Prophet Sin'gurath has a hard enrage timer of 10 minutes on LFR and Normal mode. This time limit is reduced to 9 minutes on Heroic mode.











Void Portal
Within the Void Portal lies a single Void Spirit that possesses within it the dark powers of the void itself. Additionally, Prophet Sin'gurath will not use any special attacks for the portal's duration. His Shadow Lash stacks will reset upon the Void Spirit's demise. Void Spirits in both portals share health.
 * 18,900,000 (10-man Normal)
 * 22,500,000 (10-man Heroic)
 * 29,500,000 (25-man Raid Finder)
 * 37,800,000 (25-man Normal)
 * 45,000,000 (25-man Heroic)



Void Monstrosity
When Prophet Sin'gurath reaches 50% health, he will phase himself out and unleash a Void Monstrosity that seethes with shadow fury. The Void Monstrosity must be defeated in order to make it out of this phase.
 * 56,000,000 (10-man Normal)
 * 69,200,000 (10-man Heroic)
 * 140,000,000 (25-man Raid Finder)
 * 168,000,000 (25-man Normal)
 * 207,600,000 (25-man Heroic)







The Prophet's Shadow

 * 102,900,000 (10-man)
 * 308,700,000 (25-man)
 * 308,700,000 (25-man)









Strategy
Prophet Sin'gurath starts off as a tank and spank boss at the beginning of the fight. His Shadow Lash buff deals healable damage but can stack high if he continues attacking for a long time. A good way to counter this attack is to taunt kite him between two tanks(OT being at max taunt range, then MT taunts back). Doing this correctly should reset the 5-second stacking buff on him.

His next ability is a single target attack known as Devastation Bolt. The obvious way to avoid its oneshotting mechanic is to spread out from one another while staying outside his 15-yard deadzone (which if enough players are close to him, he'll use this attack on the MT). The damage is healable if no extra player takes the hit with an already designated target.

Another attack used by this boss is Crushing Void. Just like Devastation Bolt, the best way to avoid this from becoming nasty is to remain spread out. Quickly heal whoever gets this debuff and when the effect expires, it shouldn't jump to another player. Again, the damage is healable if it affects one person every 30 seconds instead of it jumping from player to player albeit increasing in damage.

90 seconds into the fight, and every 90 seconds from now on, the Prophet will open up a portal near a random player. Everyone in that area will be knocked away. Afterwards, players have a 30-second window to enter the portal. However, only a certain amount of players can enter any given portal at a time. Mostly damage dealers will go into the portal but a healer will be necessary to deal with the damage.

Once inside the portal, players will be given a debuff called Essence of the Void, which removes any cost to players' spells and abilities. Use this along with any available damage cooldown to kill the add inside quickly. Once the add is dead, the debuff is refreshed (30 seconds) which is a benefit if good DPS and atleast 1 healer enters (for 25-man, bringing atleast 2 healers for the portals and the rest as dps will bring the add down quick). Prophet Sin'gurath will cease all special attacks while the portal is open. Therefore, all that needs to be managed outside during the portals is tanks taunt kiting the boss when necessary as his Shadow Lash will still be functioning.

Prophet Sin'gurath continues using his arsenal of attacks until he reaches 50% health. When this occurs, he'll summon another add known as the Void Monstrosity. Start off stacked up and with the add in the middle of the room. The Monstrosity's main attacks are Void Slice and Dark Lightning. Dark Lightning will come first so be prepared to spread out just enough that the attack doesn't chain to other players. Be warned, while Dark Lightning comes first, its 2-second cast means players have 2 seconds to group up after the lightning to split the damage from the incoming Void Slice.

Using Bloodlust/Heroism when this phase starts will be extremely helpful in getting through it quickly and with little to no deaths. Once this add is down, its just a home stretch from 50% to 0%. Be mindful that Prophet Sin'gurath will begin using his attacks right away once the Monstrosity phase is over.

Remember to spread out for Devastation Bolt and Crushing Void attacks, taunt kite (or ping pong) to reset Shadow Lash, and enter the Void Portals to kill the add. Doing all of these will guarantee a clean kill.

Heroic Changes
Aside from an obvious health and damage increase the following has changed when Prophet Sin'gurath is fought on Heroic Mode:
 * Shadow Lash's damage is reduced to 35,000 but the stacking buff duration now lasts 1 minute, up from 5 seconds.
 * Prophet Sin'gurath now targets two players with Devastation Bolt instead of one.
 * Prophet Sin'gurath will open two Void Portals at a time instead of one and will do so every time he loses 10% health.
 * All players are allowed to enter any Void Portal when they spawn.
 * The Void Spirits that exists in the portals will share health.
 * Essence of the Void reduces healing effects by 20%.
 * Prophet Sin'gurath gains a new ability called Shadow Rage.
 * The Void Monstrosity's Void Slice will drop a void zone underneath its target.
 * When damaged to 90% health, Prophet Sin'gurath will spawn a Shadow of Sin'gurath, introducing an additional phase to the fight.
