The centerpiece of the anniversary events will be the debut of a free dungeon that will reference the game’s history and popular characters. “It’ll also give you the opportunity to defeat some ‘devs’ in battle,” Executive Producer Severlin wrote. “Yes, I plan to try to kill you in-game.”
DDO is also preparing a brand-new race for Update 30: the Gnomes. The race will include a Deep Gnome iconic version and will be about the same height as a halfling (albeit with a little more heft and facial hair).
