Felldew is a powerful drug found on Elytras which glows a faint green. It is highly addictive with powerful withdrawal effects. In the quest "Addiction", the Hero must consume Felldew, immediately turning them into an addict. Failure to consume more Felldew incurs negative status effects. While Felldew is an alchemical ingredient, the only effect listed is the "Felldew Effect". It can, however, be turned into a potion when mixed with a Heart of Order (the resulting potion being either one of the Felldew Effect or one of Jyggalag's Favor).
