Though I discovered the stairs within a few minutes, I’ll probably need to fight the floor boss. The circumstances looked a bit different this time around though.
A wall of rock that wasn’t there up until now, surrounded the stairs, isolating it from the outside world.
On the inside of the rock wall, pure sand that echoed my steps to a certain extent spread from the entrance to the exit and a small pond of spring water was on the opposite side of the stairs.
As I advance on foot, the entrance behind me was suddenly blocked off by a huge rock that rose up. At the same time, the stairs in front of me were hidden by a large amount of water – a waterfall pouring down from the ceiling.
Though there was an escape path up until now, it seems that it is currently impossible to run away.
So you either kill the floor boss, or get killed by it?
And so, this place was properly set up, while the boss of the 15th floor, slowly rose up from the pond near the stairs.
The boss of the 15th floor was a huge crab.
It had thick shell dyed in an irregular patter of blue and red, its back covered by countless of hexagonal prisms formed out of Amethysts, Citrine, Rose quartz and Morion.
The massive, overpowering figure of the one facing me reminded me of heavy industrial vehicles, such as a dump truck or a bulldozer.
On its right hand, it developed saw-like scissors like a fiddler crab. It vibrated at high speed and sparked every time the blades touched one another, producing a high pitched sound at the same time. Four red compound eyes stuck out of the front edge of its cephalothorax and were observing its surroundings. Red and white bubbles were being blown out (*bubble bubble (sfx)*), dissolving anything they touched.
The floor boss’ name was "King Crab ・ Crysora".
The shell and the crystal can be collected as materials for high-ranking magic items, and the crab is a delicious type of monster.
