The entire expansion could almost be thought of as a graduate course for Dungeon Siege II players, as you'll encounter a range of difficult opponents to battle. Since you'll start the expansion with a high-level character, you can expect some equally high-level enemies. Some opponents take a page from Halo's Flood and will explode at death, which means they'll try to use that against you. The behaviors and artificial intelligence have also been tweaked, so you'll see enemies that spawn other enemies, and the spawners will stand off and try and let their minions take care of you. The only way to deal with them is to take out the spawners first. Meanwhile, other enemies may lay dead and wait for you to come close or pass them before raising themselves up to strike.
