Ok I'll tell you but I'm not going to post links as I'm not sure Diablofans would allow me to do so.
Blizzard has a set of CDNS servers across 3 providers. When you download via their installers or via the launcher there's always a http download stream from one of these servers. It doesn't matter if your installing a PTR , a beta or something that's live , the original source will be on one of these CDN servers. So before it goes live to the PTR , Beta or Live Live it gets uploaded to these servers.
Now each "type" of download has a program identifier. Wow is "Wow" , WoW PTR is "WoWT" , Wow beta is "WowB" , SC2 is "SC2" , SC2 beta is "SC2B" on so on and so forth. So if we were looking for a Diablo 3 beta the identifier would be "D3B"
Now if you know where certain headers are stored and know the arcane art of reading & interpreting them you can use it to glom together a direct download link to patch files and hence download patch files without need of a installer or launcher. That unfortunately isn't me.
But I do have a friend that has a bot that watches for changes in amongst the CDN servers and sends an email out for any changes it sees. On the 10th September @ 21:30 GMT it sent one out "New build for D3B - enUS: 19080" then on the 11th @ 20:50 GMT it sent out another for "New build for D3B - enUS: 19177"
I've been scratching my head over the last two days trying to figure out what it was. The emails do have direct download links to MPQ files but I'm not sure if I'm allowed to post such links. I honestly thought it had something to do with a PC based client for the Console version of Diablo 3 (hey don't hate ! I don't follow the news on Diablo 3 that closely >_> )
But rest assured this info has a very good probability to be true - there are MPQ patch files out there for a "D3B" that , as I've explained above has to do with a Diablo 3 beta.
I confirm that Blizzard employees are testing various elements Reaper of Souls, and some of these items are available on the test server. I remind you that the data is a test server and they are by no means final. Also warn against spoilers contained in these articles. Information on the progress of the development of the addition we will publish on our official website.
Hmm the new titles should be fun. Nice to see them being implemented hopefully. Also can't wait to form a clan/guild with my friends. So much info. Though it does confirm something I've been thinking since I saw the Gamescon footage. They are a lot further along with the xpac then they are saying. From what it looks like with this much data and the info stated previously about the servers. I am guessing they are at atleast a Alpha in house or friends and family build phase. I'd guess they are going to announce beta at Blizzcon.
From this leak elemetal damage effect Blizzard is testing are
Lightning jumps to many targets.
Fire deals periodic damage.
Arcane has a chance to charm.
Holy heals you.
The ring that boost poision damage says it double only damage of poision damage so I don't know what's poision effect.
