Obsidian

Obsidian is a naturally occurring volcanic glass refined from raw obsidian which can be obtained through mining. Notable for its glossy black hue, the felsic stone has many uses, from weaponsmithing, enchantment, and jewellery. Raw obsidian is mined from hilly and mountainous areas. Prior to the adoption of widespread adventurer mining, obsidian could be purchased from commodity shops such as those in Blackrock or Ogalla.
