Grim Batol is a mountain fortress located in the Twilight Highlands. It has great walls and spires that reach toward a steel-gray sky, but the stronghold’s bulk is underground. Founded by Wildhammer dwarves and later captured by orcs, a flight of red dragons now command Grim Batol. The dragons guard a secret power within the fortress and let no one near.
The entrance is at [19, 54], where you follow a path curving south to get to it at[73, 70]. Do not try to enter from southeast Wetlands near its position on the map; you must take the north entrance.
Grim Batol Achievements
In the fortress instance of Grim Batol there are only two achievements that you need to complete for the Glory of the Cataclysm Hero achievement. They are found at the first and last bosses and called Umbrage for Umbriss and Dont Need to Break Eggs to Make an Omelette.
This achievement is only slightly harder than the easiest ones due to the ease of accidentally killing the infected too early, and the difficulty of healing the tank if the buff is left up too long. Done properly the fight is not too difficult though.
The trogg that has the disease is the purple one that spawns with the 3 normal ones. As soon as it spawns someone needs to pull it aside and CC it until much later in the fight. Good choices here are hunters with ice trap, mages with poly, or even druids with root. Once the infected purple trogg has been moved aside and CCed the fight progresses as normal, with the tank saving all his cooldowns for the next part of the fight.
The fight changes from the normal plan at about 10-15% health left on Umbriss. At this point the tank should move the boss next to the infected and CCed trogg and DPS switches to the trogg to kill it off. This will give Umbriss the trogg disease, buffing him to cause 50% additional damage. The tank then starts popping his cooldowns in sequence while DPS kills the boss. The healer will also want to have any cooldowns that they have ready to help keep the tank alive as damage will be extreme. If timed right though, you should have less than 10% of the bosses health left to deal with and be able to down him in less time than the tank's cooldowns last.
This achievement is not really anything special. While some groups ignore the basic mechanics of this fight and brute force it down, to earn the achievement you need to do the fight the way it is meant to be done. This means that after each time the boss casts eye of the storm and the two faceless corruptors are summoned, that players be in position and ready for them.
Since the corrupters can not be rooted or CCed it is not possible to completely stop them. However, any slow effect you have will affect them and must be applied as soon as they spawn. Some of the slow effects that will work include Chains of Ice, Frost Traps, Crippling Poison, Hamstring, Earthbind Totem, Wingclip, and more. To make things run smoothly, make sure you assign which player will be slowing which add (right or left) as they come out.
Once both are slowed, DPS should first focus on one, then the other, all the time keeping both under slow effects. The key here is to ensure players know which add they are to slow, and which add is to be focused down first. Once everyone is coordinated, the fight should be easy.
As long as you have 3 solid heroic geared DPS players, 2 of which have slow effects, and you get to the adds as soon as they spawn it should not be an issue. While you can potentially do this with the healer or tank applying slow effects it will be slightly harder as the tank would need to be moving around and therefore potentially take hits in the back and suffer higher damage.
War of the Three Hammers
After losing in a three way civil war between themselves, the Bronzebeards, and Dark Irons, Khardros of the Wildhammer clan led his people north through the barrier gates of Dun Algaz. It was here that they founded their own kingdom within the mountain of Grim Batol.
After years of bitterness, Thaurissan, leader of the Dark Iron clan, launched a double-sided attack from his city in the Redridge Mountains against bothIronforge and Grim Batol in hopes of taking all of Khaz Modan. Thaurissan led his forces against Ironforge while his sorceress wife, Modgud, attacked Grim Batol.
The Bronzebeards were able to push back the Dark Iron assault which had been led by Thaurissan at Ironforge. As Thaurissan withdrew to Redridge, Modgud's forces began to break through the gates of Grim Batol. Modgud then used her sorceress powers to call for the shadows from the earth to attack the Wildhammers within their own fortress. The Wildhammers viciously fought back against the shadows and the Dark Iron forces. Finally, Khardros was able to push through the invading onslaught and slay Modgud.
Leaderless, the remaining Dark Irons began a hasty retreat to Redridge only to be intercepted by the Bronzebeard army which had come from Ironforge to assist Grim Batol. The remaining Dark Iron forces were crushed between the Wildhammer and Bronzebeard armies.
Following the total defeat of Thaurissan, the Wildhammers returned to their home in Grim Batol. What they had found was that the death of Modgud had left an evil taint in their fortress. The Wildhammers found Grim Batol uninhabitable and founded a new home in Aerie Peak.
Aftermath of the Second War
During the Second War, Grim Batol was the center of all refining operations for the Horde's navy. It was also the main base of the Horde's dragon breeding program, where Alexstrasza the Red was kept captive and forced to produce red dragons to be used as mounts for orc dragonriders. The Horde used the Demon Soul and Dark Iron chains to control the red brood. Grim Batol remained in orc hands long after the collapse of the Horde and the destruction of the Dark Portal, largely due to the power of their dragons. Eventually, thanks to the efforts of a band of unlikely heroes led by the mageRhonin, Alexstrasza was freed. The dragon queen immediately set about incinerating every orc she could find, utterly destroying the power of the Dragonmaw clan (in Azeroth) and killing the orc warrior (former warlock/former shaman)Nekros Skullcrusher.
World of Warcraft timeframe
Members of the red dragonflight were left behind to keep watch over Grim Batol, and for years they successfully guarded its desolate halls from further intrusion. The red wyrmGarshilan leads the fortress' defenses, aided by the young Acridistrasz and theDragonspawn Baleflame.
The ruins of the orc caravan that tried to escape the fortress can still be seen strewn around the entrance.
In the novel Night of the Dragon, it is revealed that Deathwing, the insane Black Aspect and ancient enemy of Alexstrasza, resides deep inside Grim Batol.
