Test Realm XP Glitch
[Subscriber Only][Test Realm]
I haven't tested this on live yet.
In the Hell's Heart zone of Stonehenge, the boss Errgoth can spawn two imp minions run around and be annoying. On the test server today, I was using the wall glitch that makes Errgoth run at you constantly, and noticed a lot of my skills couldn't hit him. I let him hit me some, he spawned his dudes, and when they died, I got full XP for them. I went in between the running glitch and him being able to hit me and got him to use the spawn move enough where I got about 1.5 levels before i finally killed Errgoth.
