Since the other thread got locked amid elite access begging I decided I'd just release the full method. This is most likely being patched this morning so enjoy while/if you can.
To jump directly to last camp fire you have to climb the right railing/rocks near the entrance to the spider temple. Once atop the rocks you will see a small opening with a greenish abyss below this is what you will be jumping into, now onto the methods.
Last Camp single jump-
Have everyone from your party stand on the rock ledge just above abyss only have one person fall. Have person type /unstuck when they are 5900 meters away from group. This will warp you to last camp fire directly by end boss gate about 1 in 5 times, it's very random but if you fail your group will end up at First Campfire by the first boss so it's ok either way.
First Camp Fire-
See Above most known method directly ports to first boss after falling for 5-6 seconds simply type /unstuck
Second Camp Fire-
If you're unfortunate enough to not make the final boss campfire there is another chance to skip content. After killing first boss the room immediately following his gate has another jump point. Open the gate and hug left wall do not aggro ANYTHING in this room. There will be a tall jagged rock pillar have your group climb that then face left wall. You will see a pillar between you and the ledge, the pillar with have small hook like stones. Hop on to the first hook then half hop onto the second hook and finally unto ledge. You will see abyss below you here you only fall for a VERY short amount of time so jump type /unstuck and about 1 second later hit enter. This will take to Second camp fire right before egg sac spider room.
Good luck hope this helps someone all methods have been tested numerous times by my guild. It is possible to get back to back boss 1 jumps but very unlikely. Anyone who tells you they can do it every time is lying and most likely trying to scam you. Enjoy.
