Forge of Souls is a dungeon in the World of Warcraft game. The level range for the normal dungeon is 75-80. The instance was released in the Wrath of the Lich King expansion. The dungeon contains 2 bosses. The end boss of Forge of Souls is Devourer of Souls.
The Forge of Souls is a short dungeon, it has only two bosses. One of the bosses you might recognise as she is identical to one of the bosses you saw in Black Temple in the previous expansion. This was one of three dungeons that was released just prior to the release of the last raid, Icecrown Citadel where Arthas Pendragon, the Lich King watches over his Undead Minions from high above.
The location of the entrance is beside the other pre-Icecrown Citadel dungeons and its easy to make the mistake of entering the wrong one. The Forge of Souls is the one on the left as you face all the dungeons. The nearest flight point for both factions is Crusaders Pinnacle then you need to fly west to the dungeon.
Once you have finished the dungeon, Jaina Proudmoore, leader of the Kirin Tor appears and offers to take you to the next dungeon in the series of three.
Bronjahjm will take you on solo without any adds or minions. About 20%, he will create a whirlwind around himself which will mean that you have to get up close and personal with him. If you stray into the whirlwind, you will receive some damage. Near the end, he will fear people to walk into the wind so prepare yourself.
You will probably notice the boss looks like one of the bosses from Black Temple and you'd be right. During the fight, the boss will put a debuff on you which will mean all the damage you do to it, it'll do back to you so you should be aware of when the debuff occurs and stop the damage. The Devourer will raise an army of ghosts who will do little damage but they can't be killed, they'll just die off. The Devourer will spin on its head and use different faces to attack but the boss is quite simple enough.
