- You can now challenge another player or party to a duel! Right click on them and select "Challenge to Duel". If they accept, you'll immediately be teleported to a PvP arena. If you challenge another party, the parties will fight each other. If you challenge someone in your party, only the two of you will fight. The resistance penalties used for the arena are those of the difficulty that the challenger was in.
- Added a new Intelligence skill - Flameblast: Channels to build up a large explosion. The longer you channel, the larger the area of effect and damage of the explosion. The explosion occurs after using another skill or after a short period without casting.
- Flameblast is first available to the Witch, Templar and Scion from the "The Caged Brute" quest in Normal Difficulty and to the Shadow from "Delving into Sin".
