Aaron finally chose the Wolf Dungeon from among the two dungeon choices he had.
The reason behind that was simple. Both of them are loot dungeons, not experience dungeons. So, he wouldn't get any experience here but would get loot in its place.
When it comes to loot, wolf loot is better than goblin loot. The credits he would gain for the wolf would be higher than the goblin loot, as the demand for the goblin loot is very low.
Though they can be used in many alchemical products, their usage is not very high in the academy. While outside, alchemical products made from goblin loot were in demand, here, the demand is not that high.
When hunting outside, those alchemical products are used to lure and anger the monsters out there, but inside dungeons, that doesn't work as the monsters inside are not real. They are entirely made up of mana by the dungeon core.
