Faerzress Fungi

Uncommon illicit substance Faerzress-infused fungi is one of the more insidious exports to come out of the Underdark. The weird magical radiation that suffuses the tunnels of the Underdark often seeps into the vegetation of that dark world, giving the growths arcane – and addictive – properties.
If transported to the surface world, a Faerzress Fungus is held in dark and damp containers, but must still be quickly consumed lest it loses its magical qualities.
While under the effect of Faerzress Fungi, a user emits a faint glow, often pink, purple or green in hue, and will often move in twitches and behave erratically. Prolonged use can cause these traits to become permanent. Many long-time users develop eccentric behavior or become outright insane.
Faerzress Fungi is also known as 'Underdank' and 'Faze'. Users often refer to the consumption of Faerzress Fungi as 'going under' or 'fazing'

Dose. A handful of dried fungi. A single dose usually costs around 50 gp on the surface, but might sell for as little as 10 gp in the Underdark.
Use. You can eat a dose of Faerzress Fungi as an action.
Effect. Immediately after consuming a dose of Faerzress fungi, your skin begins to crawl and you start to feel an eerie and otherworldly sensation.
