Sacred 2: Fallen Angel Interview

Gaming Nexus has kicked up a four-page interview with cdv Software's Mario Kroll about the soon-to-be-released Sacred sequel they'll be publishing in the US.
During CDV Editors Day 08 we saw some monolithic bosses: The Nautilus, the Golem, and the Red Dragon. What other bosses are lurking around the land of Ancaria? What makes a good boss monster in your opinion?

Each of the 12 regions has a boss battle. In Sacred 2: Fallen Angel, we wanted to keep game play as open as possible, although it's not really a sandbox game. But we didn't want to impose artificial restrictions that keep a player from playing the game their way. The bosses are tough, and defeating one requires not only brute strength but also figuring out their unique weaknesses, particularly at the higher difficulty levels. (Silver, Bronze and Hardcore are available in a new game; once completed, Gold, Platin, and the extremely tough Niob difficulties are unlocked, by the way.)

A boss, at least in Sacred 2, serves as a true challenge to the player, just prior to completing a major milestone. A good boss monster is one that the player can defeat, but its neither a trivial or a mindlessly repetitive experience. It should challenge the player in an intelligent way and also keep players from wandering too far into areas of Ancaria that are too lethal for their current skills or experience, or the their party composition.
