Irid moss grows within natural underground caverns. It is bright purple and glows when unpicked, hence its name "Irid", or Iridescent. Concoctionists seek this herb out often and actively for its healing properties. When eaten on its own, it restores health and mana, and can be used in conjunction with health and mana elixirs, it can also be used for concocting mass salves.
