This is for the Gates of Arah dungeon. To help farm shards for the gear. This guide encompasses a quick run that kills the first 2 bosses. You get 2 boss tokens which is 4 per so 8. It takes about 15 minutes to do maybe less with higher dps. This exploit isn't groundbreaking or revolutionary all you do is Pick up the Warden Illyra expo mode.
I'm going in for another run will time it. But essentially what you can do to skip some pulls for the 2nd boss kill the 2nd boss, continue on or do whatever you want reset it with the relog glitch.
After the first boss you get to this point in the first room you were at
Jump the coral and at the peak you will be instantly at the 2nd boss
