I found tonight that in Deadmines that if you can get ontop of the hut that Vanessa Vancleef and Cookie spawns in, you can avoid most all damage in the fights against Ripsnarl, Cookie and the final portion of Vanessa Vancleef. I used my Reins of the Grand Black War Mammoth - Item - World of Warcraft, but I believe any Mammoth will do.
The process is fairly simple, and requires you to be able to Mammoth Mount Jump, which is essentially summoning your mammoth and at the last second jumping up or jumping forward so that when the mount summons it pushes your player up with no regard to collision, then the mount disappears and leaves you up a few meters higher to do it again.
1. Start in the red circle behind the Battering ram or whatever they actually are
2. Mammoth Jump to the top of the small wooden device
3. Mammoth Jump into the small corner that my player is directly above in the SS
4. Profit: I remained there for the duration of Ripsnarl and Cookie fights and took little damage form Ripsnarl's adds and none from Cookie. But I also was not targetd with any food, good or bad from Cookie. I was also able to get back up on the roof before we re-engaged Vanessa and did not need to take the rope swing, because the flames couldn't reach my position.
NOTE: Coalesce will still damage you up here.
As a dps, this is useful because, less motion more time to dips, I would suggest going in and getting the healer up on the roof as well to make things even easier.
I hope you can all find uses for this, Enjoy!
Any responses positive or otherwise are appreciated!
