Bone can be used in place of wood and steel in weapons and armor. Other animal-based materials like horn, turtle shell, and ivory also use the rules for bone weapon and armor.
Studded leather, scale mail, breastplates, splintmail and shields can all be constructed using bone. Bone either replaces the metal components of the armor, or in the case of shields, large pieces of bone or shell replace the wood. They are one quarter the weight of their base armor, and have the fragile property. The armor/shield bonus of bone armor is reduced by 1. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the bone version of the armor doesn’t.
Light and one-handed melee weapons, as well as two-handed weapons that deal bludgeoning damage only, can be crafted from bone. Hafted two-handed weapons such as spears can be crafted with bone tips, as can arrowheads. Other two-handed weapons cannot be constructed of bone.
- Bone weapons have the the fragile property.
- Bone weapons take a –1 penalty on damage rolls (minimum 1 damage).
Armor and Weapons made from bone cost one tenth as much as those made from steel, but they are not normally available except in those cultures that use them such as the Kender.
Fragile weapons cannot take the beating that sturdier weapons can. If you roll a natural 1 on an attack roll with a fragile weapon, you must then make a DC(10) Dexterity (Sleight of Hand) save or that weapon is damaged and only does half damage after that. If already damaged, the weapon is destroyed instead.
Armor with the fragile property falls apart when hit with heavy blows. If you are wearing fragile armor and are hit with a critical hit, you must make a DC(10) Dexterity (Acrobatics) save or the armor is damaged and the AC bonus it provides is halved. If already damaged, the armor is destroyed instead.</p>
