Spindleweave

Description
Spindleweave is a small plant with translucent stems and leaves. It flowers for only a single day each year and its flowers are pale white. The stems can be used to brew potions that cause the drinker to become invisible.

Special Rules
Spindleweave may be used by any character with Brew Potion. Using an additional 5gp of materials, the brewer can create a potion of Invisibility (as the spell) that lasts for 10 minutes.
