Cuirasses are a part of the Leather Armor set, worn by archers, warriors, and slayers. The set also includes a pair of gloves and a pair of boots. The Leather Armor set provides medium defense and balance modifiers, allowing the wearer to occasionally take the hard hit.
Cuirasses can be obtained from various methods, including NPC shops, other players via direct trade or via the Brokerage, enemy drops, reward from quests, or crafting through the skill Leatherworking.
