A juvenile Dark Grung being ground up to a pulp by a mortar and pestle for use in Lesser Grungine.

Grungine is an opioid used as a recreational drug, made from the poison present in the juvenile bodies of Dark Grung, which are small froglike creatures related to the more common tropical colorful Grungs. Grungine can only be made from the bodies of juvenile Grungs since only their undeveloped and weaker poison has the desired effect. Grungine made from the bodies of mature Grungs can be fatal and often is.

Grungine's is known for causing deep euphoric trances, persistent lucid dreams, but most famously it's known for allowing grung-vision. Common side-effects include: addiction, lucid dreams, mental unraveling, and a crippling aversion to frogs.

Lesser Grungine (AKA Grunge)

Item, uncommon. 10 gp per dose.

Idiot Strength. For six hours after waking from the trance, you have +1 to any Strength checks.

Addicted. Use grungine daily, or take 1d8 Psychic damage per day. After 30 + (1 for each time used) days of abstinence, the addiction stops. If grungine is used again, you will automatically become addicted once more.
