Diablo had Physical Immunity

[jbtilley]

The one time I went to kill Diablo he was immune to physical.  Is that hard coded in, or did I just get really bad luck of the draw.

It took forever and a day to kill him, that and you have to do the entire act 4 in one sitting thanks to the spread out seals.  Doing act 4?  Free up 3-4 hours.  Ha.

this was a random immunity
u just have to go to town for 2-3 minutes
then the immunity has changed

That works not every time. If, Diablo have after town move his immunity, you can left the game for 1 sec and than come back.
