Ok since theres alot of speculation about the beta i can fill people in as im in the beta....
Soulbound -> accnt bound whatever toon type id's the item will have that main stat i e agil DH str barb
Legendaries soulbound after 2 hours (trad-able to party members on drop until so)
Blood Shards -> farmed from Bounties and Rift Boss's used to gamble gear from a gamble vendor has a chance of legendaries i have gotten 6 or so from it
Gold = useless atm
Gems used in crafting and enchanting... talk about removing bindings
Enchant allows you to reroll 1 stat i.e str-> dex as a gamble 1 of like 8 stats can be chasen requires forgotten souls to do so to legendaries (legendary salv)
Gold is not BoA
anymore questions?
p.s. this is all subject to change as it is beta
