Ozruk

Ozruk is the third boss of the Stonecore.

Adventure Guide
''Ozruk has served as Stonecore's guardian since Deepholm's creation. It is unknown why Ozruk has remained in the Stonecore, but it has become apparent that the guardian now believes that anyone opposed to Deathwing is a threat to Deepholm, and should therefore be destroyed.''

Strategy
Ozruk should be pulled into the tunnel and tanked against a wall, this is so that on the knockback the tank will need minimal repositioning, the tank should run to the opposite wall and continue tanking as normal.

Heroic Difficulty
In heroic mode, there are a few changes. Periodically, he will cast a paralyze debuff on the party, followed by a spell called Shatter. The paralyze effect lasts for eight seconds, and deals about 50,000 damage when it expires, this damage can be avoided by removing the debuff before it expires. Paralyze can be broken by taking damage and is also dispellable. There are a couple of ways to deal with this:
 * Elementium Spike Shield causes a bleed effect on players if they attack the boss while it is active, therefore placing a DoT, melee damage will gain you the bleed effect in normal combat. This will then break the paralyze allowing you to move away from his Shatter attack. For casters, Elementium Bulwark has a 100% reflect chance in Heroic, reflect a spell that has a DoT component that lasts a minimum of 12 seconds will break you free of Paralyze.
 * Melee DPS/Tanks: Melee damage will always get you the debuff and break paralyze. Move away from Shatter in the same manner as normal mode.
 * Ranged DPS: Keep your normal rotation, staying away from the boss as normal, reflect a spell with a DoT mechanic to break your Paralyze effect.
 * Healer: Any DoT will work, such as Judgement with Seal of Truth for Paladins. Ensure you have a damaging spell off CD at all times to allow for this.
 * The effect can be dispelled, so if a class capable of dispelling is not affected they can free other players, however, due to the short amount of time given to move away it is not advisable to rely on this.
 * Hunters are the only class that can't break Shatter on their own (except with Bestial Wrath) so healers should be aware and ready to dispel any hunters who may be in your party.
 * Really the only way to cause damage to yourself if you can't get rid of Shatter for whatever reason is to drink Sulfuron Slammers, bought in the Grim Guzzler in Blackrock Depths. If you don't have Direbrew's Remote to port yourself to the bar, you can probably find someone who does.

After casting Paralyze, Ozruk will begin to cast Shatter, it is essential that your group is away from the boss as this will one shot most players (including tanks).

The other main ability in heroic is his Ground Slam, which will erupt a cone of spikes from the ground in the direction he is facing. There is a cast time on this so the tank should ensure he is facing away from the group at all times and once Ozruk starts casting the tank should temporarily move behind him. This ability will one shot a tank. Melee and ranged should not be infront of the boss, but if they are they will also need to move.

Finally, Ozruk will enrage at 25% health for 1 minute, increasing his damage by 50%. This can be dispelled with any Enrage removing ability.

You should plan to kite Ozruk slowly down the hall during this encounters, with the tank always running away from the rest of the group during the Shatter cast, so that Ground Slam will always be directed away from the party. Don't let him go too far, or you'll run into mobs on the other side of the tunnel.

A good plan to use against Ozruk is for the tank to immediately run behind him (so the tank's back is toward the narrow tunnel). This will ensure that all other party members are behind Ozruk at the mouth of the tunnel when he casts Ground Slam. Upon casting Ground Slam, the tank should run straight through Ozruk and stop behind him until the spell is done. Once the spell has been cast, the tank should then immediately go to the other side, again with his back to the narrow tunnel. Ozruk will cast Shatter soon after Ground Slam, and this method will once again ensure that he is facing away from other party members at all times. As long as the tank continues to move "back and forth" through Ozruk as he casts Ground Slam, the fight will be fairly easy.

Warrior tanks should resist the temptation to return to Ozruk after Shatter using Charge or Intercept. Ground Slam is cast very soon after the Shatter phase, and if you accidentally rush behind the boss before this happens, the boss will face the party and probably kill many of them.
