Halls of Stone is a dungeon in the World of Warcraft game. The level range for the normal dungeon is 74-79. The instance was released in the Wrath of the Lich King expansion. The dungeon contains 4 bosses. The end boss of Halls of Stone is Sjonnir The Ironshaper.
Halls of Stone entrance location is at Coordinates 39, 26. The halls are located on a large rock on the northern end of Storm Peaks on Northrend. It is one of three instances on the rock. The other instances is the raid Ulduar and Halls of Lightning. Its not easy to make the mistake of Halls and Ulduar as Ulduar is high above in the hills.
The next boss as shown as blue on the map is a giant maiden, like what you encounter in Uldaman and in the raid Karazhan. The Maiden will drop black clouds on the floor which you must avoid. Unlike other female bosses in the game, this boss doesn't drop the christmas hat.
Krystallus is easy to kill, you must remember though that this boss can turn people to stone and thus render the player useless for the rest of the fight. Krystallus can throw people back so its best avoid him as much as possible although easier said than done for melee, just run therefore before Krystallus does his special move.
Before you get to the third boss (Tribunal of Ages), you encounter the Dwarf explorer Bran who will help and start the third boss. The third boss unlike all other bosses in the game isn't a boss, just loads of adds that you must kill so that Bran can access the computer and move onto the final boss.
Brann Spankin New Achievement
When the fight starts, the dwarf explorer Brann is at the back of the room. You must stop all and every add from getting to Brann. There is no single boss in the battle so you need to watch every add and kill them before they get to Brann.
The final is a giant human who causes a load of adds to come. If you're in a rush, just tank and kill the boss, however if you're up for an achievement, let the blobs adds to coalesce. Halls of Stone are now done.
