The Hobgoblins were all close to breaking through to the next major Level.
:Hobgoblin, Level 24; HP- 2900/2900:
The twelve Hobgoblins weren't too much of a threat for him, but the bigger creature was strange. It was an extremely fat Goblin that had likely evolved from one of the Mage classes.
It was sitting in the middle of the room, its rolls of fat laying over its legs. The way the Hobgoblins were handing it corpses made him think that it couldn't move. This creature made him excited.
:Goblin Gourmand, Level 25 (SUB-BOSS); HP- 11,750/11,750:
'Albus, what exactly is a sub-boss in these Dungeons?'
:A sub-boss would be best described as a creature that has become powerful on its own. It earned its own name during evolution, be it through killing other types of creatures or through unnatural means.
