To obtain the obsidian armour set, the player must smith the components using Obsidian bars, which they must make themselves by smelting Obsidian shards from the Fight Cauldron Minigame, available after completion of "The Brink of Extinction" quest. The names for all obsidian equipment, except for the Obsidian armour set and capes (obsidian cape and fire cape) are in the TzHaar language, unlike other types of equipment.
