You have to kill 20 elite bosses to get the free war chest. Not many people will ever kill that many, me included.

I like the free trip to the mines. On Friday night, I paid 10 plat to join and it took half an hour for me to get enough people to do a run. After 40 min fighting the wolf (he reset a few times), everyone left. I could not get another game. I was trying to get the elite boss achievements. Maybe I can get one of them now.

I love the reduced aggro. However, I still don't understand why it creates any aggro.
