You need wow gold buy weapons help you to do it.
As a WOW GOLD player, you'll discover a ton of Alliance/Horde slaves are working in the pit. You need to free 15 slaves and Garfrost dead to advance. Kill the enemies near the slaves to release them. You'll get 15 in no time. Then head up to Garfrost for a fun battle. You need wow gold buy weapons help you to do it. Just want to hug you with big weapon. Garfrost is a three phase battle where he doesn't like you and it shows. He can throw boulders and comes with a room packed with baddies. Kill all of the baddies in his room and then focus on him. In the first phase he'll throw rocks and beat on the tank. His attacks do apply Permafrost which increases frost damage done by 10%.
When phase 2 starts he'll stomp the group and run off to a forge. Let any debuffs tick off and meet him again. This time he'll do 50/100% more frost damage. Keep dodging boulders and avoid his Chilling Wave which is an AoE cone effect in front of him. In phase three he'll boost his frost damage to 100/200% and cast Deep Freeze which snares a target. So dodge boulders and smash his face in. When that is done you'll have to move on over to Krick and Ick to open the path to he final boss for the quest you'll be given here. Krick and Ick are weird, to say the least. Clear the area around Krick and Ick very well because adds will wander into the boss area frequently if you don't.
