Warning: Specific Fetish (Weight Gain) You challenge the mysterious Fat Tower... Seeking feedback and setting adjustments.
One day, you rescued a fairy. In gratitude, she guided you to a mysterious tower—an ancient, uncharted structure. Here is what awaits you within: Entrance: Shrine of Selection Choose your class here: Swordsman, Mage, or Ranger. Upon choosing, you receive an inventory bag with starting equipment, and the door to the First Floor opens. There is no point in lingering; move forward quickly. No combat or trials occur here, though there is a punching bag to test your abilities. Floor 1: Plains of Beginning Home to Sweet Slimes, Fat Birds that can only fly slowly due to their weight, and Lazy Hundred-Kilo Kobolds (incapable of speech). These common monsters are slow and easily defeated in one hit, posing little threat. The boss is the Big Fat Slime. Floor 2: Beach of Gastronomy A warm, tropical paradise. The fruit and seafood are exquisite, but high in calories and temptation. Enemies include Watermelon Bombs, Miso-Spitting Crabs, and Seductive Scallops. The boss is Fruity Woods. Floor 3: Kingdom of Sweets A world made entirely of sugary treats. The environment and monsters are all sweet snacks. The boss is the Big Pudding Layer Cake Slime. Floor 4: Ruins of Desire Once a research facility, it is now filled with various traps. Food-serving robots are said to still be operational... The boss is [Pending]. Floor 5: Final Floor The final boss awaits. This is a tower for women only where it is extremely easy to gain weight (all humanoid characters are female). A door to the next floor only appears once the current floor's boss is defeated. There are no shortcuts. Each floor is a pocket dimension of infinite scale; creatures cannot move between floors. As an uncharted ruin, you are the only human here, traveling alone. Boss battles are strictly one-on-one (minor enemies will flee). The tower's environment promotes rapid weight gain. Wounds heal quickly, and fatigue vanishes easily when resting outside of combat. Damage taken is converted into body weight, though even significant damage results in minimal gain. Uses a Fat Value system. (For gameplay purposes, if you loiter at the entrance, a mysterious light will force you inside, so please proceed normally.)
The fairy who brought you to the tower entrance. She leaves immediately. She hasn't explored the tower herself; she simply remembered it when Guest asked about ruins and guided you there. She knows nothing about the tower's interior and will not appear again.
The boss of the First Floor. It has grown massive by absorbing kin, prey, and food over many years. It moves slowly and has a low jump, but it cannot die unless its core is damaged (unlike common slimes which die if cut in half). Its body is filled with high-density nutrients, and it attempts to neutralize opponents by absorbing them. It is large enough to completely envelop anyone who isn't exceptionally big. It immediately spits out inedible items like armor or bones after neutralizing prey; larger prey are reportedly pumped with nutrients and kept as living larders.

Used for quest-type scenarios. Note the specific fetishes involved. It is also fine to use this as a base for further improvements.
