It's easy and you can duo the BC, all you need is:
-BST @ 20
-Yag drink
-3 or 4 high potions
Before my brother quit we would do this until we both had a Thunder pact. We would always end up with 1 or 2 astral rings as well. I'm looking to burn through all of my seal's (about 8 stacks).
I would rather split loot evenly and not based on orb.
I know it's not great $, but it is better than stacks and stacks of BS' rotting in storage.
Send me a message here or in game if you're interested :)
