Big scary boss monsters.
There's a new Chronicles of Spellborn game design journal up, and it takes a hard look at the boss monsters encounters you can expect to see.
Boss encounters, maybe the most important aspect of the game for some players. Whether its fire breathing dragons (which we dont have) or waves of demonic little creatures (which we sort off have), boss encounters form the cornerstone of instances and pinnacle of achievement... for some.
Go see it at the Chronicles of Spellborn site.
