Mushrooms can be sliced in different amounts, depending on the mushroom type, to create a sliced mushroom. Each sliced mushroom awards the player with 85 Cooking, and 15 Herblore experience. Slicing mushrooms requires at least level 86 Cooking and 90 Farming, which may be boosted.
The location and amount of mushrooms required to produce one sliced mushroom can be found listed below:
Sliced mushrooms have a "Nibble" option, which can be selected via right-clicking the item inside the player's inventory. Nibbling does not consume the item, and may be done once every 10 minutes, causing a variety of random effects to happen, identical to the Hallucinogenicperk.
When nibbled, a message is displayed: Something interesting happens.
If nibbled before the 10 minutes have passed, a message is displayed: Nothing interesting happens...yet.
With the release of the second batch of The Arc, all owned wushrooms were converted into sliced mushrooms.
Previously when nibbling a mushroom, if there was not enough room around the player to perform a random effect a message would be displayed: There's not enough room here for something interesting to happen. With the release of The Arc – Chapter 2 on 10 October2016 this message was removed.
The random effects caused by nibbling the mushrooms are a reference to psilocybin.
