📋 About This Mod
Edible Acid Mushrooms
Customizable mod, makes acid mushrooms edible, applying a hallucination effect on the player.
The mod adds simple mechanic: Acid mushrooms are edible now and, when consumed, apply a hallucination effect. Hallucination effect itself is designed to greatly complicate the game causing some inconvenient effects to the player.
Each time acid mushroom is consumed, it applies a hallucination effect to the player, adding the duration to the current one. Usually, you can cure the effect using First aid kit or by interacting with something in the depth (Subnatuica story spoilers).

Hallucination Challenge
If you want to experience a real challenge with this mod, here's all what you need to do:
-
[]Enable the Permanent effect checkbox[/]
[]Enable the Mushroom diet checkbox[/]
What it does? Well, with the first setting, Hallucination effect is permanent. Now in order to remove the effect, you will have to go through the whole game and go down to the very depths. With the second setting, you will ONLY be able to eat acid mushrooms and also drink water. All other food will have negative food values (any edible item that does not affect the food value in any way is considered water).
Can you handle the challenge?!
