October Challanges (Featured)

I believe that if when the loading screen to the match comes up with the progress bar. and on the far right it will say either

Awaiting Challange...

or

Awaiting other players...

The Awaiting Challange means you are Host.

FFFFFFFFFFFFFUUUUUUUUUUUUUUUUUUUU... Thanks.

To get the Punch Diablo challenge, you have to unequip your weapon, and make sure you only use a regualr attack, no assigned skill. I haven't tried the "naked" challenges, but I'm pretty sure you can't even have weapons on. And if I remember correclty,
you have to be on Nightmare difficulty or above.

It all depends on where you live. In the UK th dailies change every day at 11am and the weekly every Monday at 11am.

They reset about 4 and a half hours from this post.
