A new balance patch was just released for the Expert Mode raids. In particular:
- On Boss 2, there is now slightly more time between waves of enemies.
- On Boss 4, the time you have to hit the bells was increased slightly.
- On Boss 5, the difficulty of the hell minions was slightly reduced.
As far as the mechanic on Boss 3, I am going to go ahead and give another hint as to what it is (spoiler tagged) – this is a pretty big hint so I think it should basically give it away. I’m also willing to answer questions about whether or not it is or isn’t something via PM if you just want to confirm.
Thanks and enjoy!
