I've been sitting on this a little bit because I wasn't sure what EN World's policy on places that violate the NDA was, but seeing as the (eventually proven to be) false leak thread over on GiantITP's forum wasn't shut down right away, I'll share.

I found an archived thread from 4chan's /tg/ where someone who played at DDXP reveals info on the build tested at the event. I cannot verify the authenticity of the information in the thread - I was not at DDXP and did not participate in the playtest - so please, grain of salt.

/tg/ - Traditional Games Thread #17721994
