The entrance to Bregmor's Lair can be found leading into the mountains halfway between Barad Gaurhoth and Jotunstath (the Ice-giant lair). Make sure to bring a full fellowship, as this is not an easy instance. Upon entering, head down the path and clear all of the mobs in your way, which includes Worms and later Gauradain as well, and should not be difficult. You will eventually reach a named Gauradan, who will run away once his morale gets low and open a previously closed gate. Head through and finish him off, then clear through several more groups until you reach a large cavern with Mordrambor and the Gauradan leader. Mordrambor will leave, and you will be left to fight the Gauradan. He has numerous adds, but seems to call in more if his present ones are defeated, so it is probably best to focus on taking him down quickly while crowd-controlling and/or AoE attacking the adds. Once he is defeated, head back to Yrjänä to claim your reward.The boss also summon a totem pole which does nasty buffs.
Tout le monde repart avec sa jolie spalière (c'est bien parce qu'on n'a pas vaincu le Baba :D ) et prêt à commencer le livre 15 qui devrait arriver mardi! ^^
