HP/inch 15; Hardness 7
Clamshell armor is made by connecting together various sized shells harvested from giant clams.
Items made from sea shells 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.
