Peek inside any treasure and you'll notice a few changes.
From now on, you will no longer have a chance to receive a duplicate item from opening a treasure multiple times; each time you unseal a treasure, you will find a different item.
In addition to ensuring you won't receive the same item twice, each time you unlock a treasure you will also have a chance to obtain bonus rewards. Bonus rewards are granted in addition to an item found inside a treasure, and some treasures feature multiple bonuses. This means you could gain two or more items each time you open a treasure!
After you have unlocked all items within a treasure, the list of items that can be obtained from opening that treasure is reset and the items can be earned again in a new random order.
Every treasure past and present now ensures that you will not receive duplicates, and has a selection of bonus items. If you've ever hesitated to unseal a treasure, take another look at what they have to offer!
Looking for the perfect treasure to pillage for non-duplicate riches? Try the new Treasures of Radiant Arms[www.dota2.com] and Dire Arms[www.dota2.com]. Each unseals to reveal an entire hero set, which include the first sets made available for Lifestealer and Puck. Opening either treasure also gives you a chance to find the Vestments of the Fallen Princess, the first set for Vengeful Spirit, as a bonus reward!
