The party left the dungeon with one person less and one story more to add to the mythos of the dungeon, which would circulate throughout the taverns of the budding city above.

Lucifer watched them leave then found Lucky "You have been having fun," said Lucifer.

"of course, there are so many people to play tricks on" answered Lucky.

Lucifer spoke "Some time ago I told myself that I would reward you for your efforts during the attack, sorry for taking too long because I was busy with the dungeons business", then a small round leather bag with a triangle opening appeared and was caught by Lucky, she grabbed it with a curious expression on her face then asked "what is it?".

Lucifer laughed then replied "let me show you how it works"

Sometime later a party of adventures noticed a red glow, they searched the area for any dangers then cautiously approached the area, one of the warriors stepped onto a pile of dead leaves which gave way revealing a hole filled with spikes, the man screamed on the way down and tried to grab the edges of the hole unsuccessfully, a heavy thud resounded along with loud farting sound, the man absentmindedly moved his hands through the spikes and found them to only be illusions, he looked up and found his party laughing so hard they could barely stand straight, the rogue was curled up into a ball on the floor clutching his stomach, the warrior stood up and found a small pouch under his ass then proceeded to cut it up into tiny pieces in embarrassment.

Over the next couple days, reports of this strange trap circulated throughout the taverns and the small pouches became a popular novelty item of the dungeon frequently used at parties. 

Lucifer watched Luckys antics whenever he had free time from construction, the ants had managed to dig out 3 new floors by now and he now had enough free time to fill them, after creating the lake for the Panthers the idea of some water-themed floors seemed quite appealing to Lucifer.

he started with the fourth floor and filled it with trees and wildlife similar to the third floor, then he created pipes going from the water trap towards the roof of this floor and made tiny holes throughout the roof of the cavern, water started to drip from the holes creating a pseudo rain effect, he could have used enchantments to get a better effect but he would rather save his mana for the later floors.

Now, this floor would always stay wet and make adventurers footing harder, after several hours the rain started to create channels in the ground and formed rivers leading towards the 5th floor, something seemed to be missing so Lucifer created a few minor enchantments on the walls to create fog and reduce visibility.

Lucifer tried to think of what creatures he wanted to wander the area but came up with nothing so he continued on with the next floors, the fifth floor was similar to the forth except all the water added up from the floor before it and created a swamp with 2 feet deep waters covering the entire floor.

Some of the trees from the earlier floors had trouble surviving in this environment and he was forced to replace most of them with types of mangroves and other aquatic plants, these trees did not grow as tall and their branches grew out wider near the base of the trees, some areas were so dense they created networks of roots and branches that would act like nets and walls.

He considered changing the species or modifying the trees themselves, but thought he should add the monsters on the floor before he decided how he should do that.

This part was easy because he already had in mind what he wanted to eat adventures here, he started at the bottom of the food chain like usual, first adding the tiny plants and mosses the prey would feed on, then he added several varieties of fish into the shallow waters for the bigger predators, then he modified a medium-sized fish that liked to swim around in schools.

First, he made their jaw muscles several times larger and stronger, then he modified their eyes to have poor eyesight so they would not make getting to the other side of the floor impossible, lastly he used mana to forcefully grow the fish so they could rapidly go through generations while he attempted to modify their behavior, after several hundred generations the fish began to swarm and frenzy at wherever they could find a light source causing Lucifer to laugh manically, he had expected it to take longer for them to learn, he was beginning to truly realise how powerful the abilities of a dungeon were.

After a short break he began to work on the last predator of this floor, he used a creature that looked similar to a crocodile then simply enhanced the strength of their scales and bite strength, adventurers would line up to get scales like these for their armors and hopefully they will be lining up to be dinner too.

Lucifer decided not to do anything to the trees at the moment and left them as they were, overall he was quite satisfied with this floor and considered it his best one yet, you either had to flail around in the dark and be ambushed by an armored razor sharp-toothed vice or use lights and take the risk of attracting a swarm of frenzied piranhas.

For the boss, he just made a snapping turtle the size of a tank, called it snappy then went onto the next floor.

The sixth floor slowly filled up with water and Lucifer had to wait for it to be nearly full before he stopped the water from rising and could adjust the runoff back into the water trap to maintain the water levels.

This floor was going to be entirely flooded, Lucifer guessed that it would take some time before everyone figured out that you would have to make boats to cross the floor, however, he made the exit to next floor underwater in a random location, the water was very murky from the runoff of soil from the previous floors making it impossible to see the bottom and it would take some time before people discovered the entrance to the next floor that Lucifer had yet to build.
