Currently - while in a party each player will see their own drops from each kill. This could mean that after killing a zombie I see a sword drop, and you may see a shoulder slot item drop. Or I see nothing drop, while you got an axe. Obviously while in a group you're killing faster, and this could translate to an exponentially increasing number of drops with each additional player in your party. However, it's balanced in such a way that the drop % is pulled back a bit with each additional player (I'm simplifying it, but that's what it boils down to). This keeps it from being almost detrimental to not play with a full party, while still giving a nice increase to the amount of drops if you do. From this system it seems quite a few people got the impression that you'll never see items drop that you can't use. For instance, a Barbarian will never see a dagger that only a Witch Doctor can use. This isn't true. There is no effect, or at least no currently intended effect, to restrict which items which classes can or can't see for their respective drops. It's still intended that you could see an item that your class can't use. It's easy enough to drop the item, ask if anyone can use it, or just sell it off of course

官方的说法非常保守,都是以现在的开发状态来回答(Currently)
主要重点整理如下
1.并非如同之前网友所说只会掉自己职业才能用的东西, 基本上掉落方式如同D2
2.对应多人游戏时杀死一只怪时每个人看到的掉落物会不同
  example:杀死一只zombie,我看到它只掉钱,你看到他掉了一把剑,他看到掉一件衣服
3.掉宝率会随人数上升而下降, 但是总合掉宝率依然大于单人

2#很牛

还没玩过呢........

楼主的帖子实在是写得太好了.可是我立刻想到,这么好的帖子,倘若别人看不到,那么不是浪费楼主的心血吗?经过痛苦的思想斗争,我终于下定决心,牺牲小我,奉献大我.我要拿出这帖子奉献给世人赏阅,我要把这个帖子一直往上顶,往上顶!顶到所有人都看到为止!  
在遇到你之前,我对人世间是否有真正的圣人是怀疑的;而现在,我终于相信了!我曾经忘情于两汉的歌赋,我曾经惊讶于李杜的诗才,我曾经流连于宋元的词曲.但现在,我才知道我有多么浅薄!  

强烈支持.楼主万岁
