Morgul-draught

Morgul-draught is a magical drink which grants the player night vision when consumed, similar to Dwarven Tonic. However, the drink inflicts damage to the player as well. The duration of the night vision and the amount of damage inflicted is determined by the potency of your drink. Note that the effects are not stackable. When drinking another beverage while one is already in effect (the same or another one), it merely resets the various effects to the largest duration between the remaining ones already active and the new ones.

Obtaining
Morgul-draughts are brewed in a barrel with three water buckets on the bottom (like most brewing recipes), three Morgul-flowers and three bones of any type.
