This table shows the health and attack by dungeon difficulty of every boss (although at Hard difficulty, it shows "reference" statistics -- boss statistics vary wildly in Hard dungeons; for example, Grimm's Grotto significantly boosts health and damage, Doubledoom slightly depresses them, and Hexx Ruins, though nominally Hard, uses the Normal statistics):
Standard stats of bosses are 75 attack and 318 health. Compared to standard level 10 monster, bosses have same attack and 2x health. All six 
 normal dungeons have 100% difficulty. However, many other dungeons have their own difficulty modifier. In this case the difficulty modifier should be multiplied to both attack and health, as well as all non-boss monsters.
Basic Bosses
Below are the basic bosses. When a dungeon says it possesses a random boss, one of this twelve bosses appears. Certain dungeon, 
 Dragon Isles for example, possesses one of basic bosses as a fixed boss.

Many dungeons have its own bosses. While some of them use the same name, it can be a different boss than the standard boss. All these bosses are based on Lv10 stats like the basic bosses, 
 Hobbler's Hold possess Lv8 boss and thus he is based on the Lv8 stat with double health boost.
