The talents of knowledge feature in Drakensang Online will allow players to win fragments of ancient knowledge by defeating worthy opponents. By investing fragments and gold, you can increase your knowledge level, increasing your damage and life force. Those who learn a lot, can even unlock teleportation.
There are also plenty of new unique, very rare armor items for all character classes for level 1-29 in Drakensang Online. This will allow you to become more powerful than ever before and hopefully gain knowledge faster.
