HP/inch 15; Hardness 7
Armor made of coral is grown, not made. Special corals are shaped and molded while growing, and then harvested and hardened to be worn as armor. Coral armor often has a bizarre organic look to it.
Items made from coral are refined and shaped through various alchemical processes. They are relatively cheap, but not particularly strong compared to objects constructed of metal. Items or objects constructed from these materials gain the broken condition after 7 days out of water and gain the destroyed condition after 7+(1d6) days out of water.
