Boss Monsters are randomly selected from the monsters on the said floor. The Green Slimes, Goblins, Wolves, Small Cave Spiders, and Cave Rats were the residents of the Second Floor. So, the boss would be an elite species from one of them.
Right now, Aster and the rest were preparing for the boss fight. Of course, they were simply distributing emergency potions, calming their nerves, and stretching. They were quite relaxed, despite it being a boss fight!
"Alright, I'll go and check what boss it'll be this time," Kali commented before she moved ahead.
The boss monster would only appear after someone got within a certain distance of the portal. For the second floor's case, that's 150 meters. Kali moved quietly and carefully stepped within range before seeing a large orb of light appear midway between Kali's position and the gigantic portal ahead.
