Diablo – Where did clans go from Diablo 3 RoS

No, the other player couldn't give you an Account Bound item. Neither could you pick up somebody else's Account Bound item.

There are 4 ways you could have one of them:

• You crafted it (Hellfire Rings, Shoulders, Amulets, Bracers, Marquise gems, Portal Devices, etc.)
• You inserted a Marquise gem into an item that made it Account bound due to the gem. If you will remove the gem, this item will become normal again(unless it was crafted as in the first point)
• You found it from some monster(Keys, blacksmith plan for Portal Device, various ingredients for Staff of Herding)
• You bought it from an NPC(bell for Staff of Herding, blacksmith recipes for various difficulties of Staff of Herding, blacksmith recipe for Hellfire Ring, etc.)

Hope it helps

EDIT

Totally forgot about one more way to get an Account Bound item. If you have a special version of the game(Collectors Edition for example), you will be granted 3 Account Bound items:

• Angelic Wings
• Bottled Cloud
• Bottled Smoke

It seems like you can also get some exclusive items by registering special versions of other Blizzard games, but I do not have any information about it

No new dyes were added to the game guide which was recently updated to include ROS items and mechanics. Unless there are any Easter eggs, it would appear no new dyes were added.
