Lanternmoss (Basic Lore)

Lanternmoss (CR 2)
Neutral - Medium - Plant
Lanternmoss is a deadly vegetable menace that also manages to be extremely useful...as long as you keep it away from bright light. Lanternmoss is typically found underground, where it ranges from the occasional patch to massive growths that can stretch for miles. In complete darkness, Lanternmoss glows with a gentle phosphorescence that provides dim light to a surprisingly large area. As a result, lanternmoss is tremendously valuable in underground passages and areas, since lanternmoss will provide a low level of illumination that many races find extremely useful. The problem arises because of the source of that light. Lanternmoss is a magical plant, and has a direct connection to the upper planes, so it is infused with positive energy. In darkness, the lanternmoss uses this positive energy to grow, and provides dim light. When Lanternmoss is exposed to bright light, however, it no longer needs the positive energy to glow and instead uses the positive energy to create a deadly aura of positive energy. This feature means that Lanternmoss beds that take root above ground...rapidly kill everything around them and can spread like an unstoppable wall of doom unless rooted out at night. Underground, a bed of lanternmoss is highly valuable, until you walk past it with a torch. Needless to say, some races like lanternmoss and will cultivate it, and some races burn it out everywhere they find it.
