Its important to say you can farm the dungeon as you like, there is not only one correct way to do this. But i usually do this route. When you have completet the route run outside the dungeon and reset, then you can go in again. Max 10 times an hour. Remember to kill and loot everything!
This Dungeon is hard to find around in due to it changes map many times doing the run, so i have tried to draw this to the best of my abillities. On many diffrenten screenshots of the map.
A fast way to get out i using the druid Dreamwalk abillity, and then using it again will port you back outside the dungeon. Death Knight and Monks have i similar abillity called something else.
Lower Blackrock Spire Drops
When you are farming this dungeon you are pretty much going for the transmog, which you can learn yourself ore try to sell on the auction house.
These mats have a change to drop at least if you run my route and kill/loot everything.
Ironweb Spider Silk
Thick Spider’s Silk
Red Wolf Meat
Tender Wolf Meat
White Spider Meat
If you have skinning, you can skin the bloodhounds inside the dungeon. These mats can drop from skinning them.
