public static ArmorMaterial aMatSchrab = EnumHelper.addArmorMaterial("HBM_SCHRABIDIUM", 500, new int[] { 12, 32, 24, 12 }, 50);

100为装备耐久度的相对值

6, 16, 12, 6 分别为头盔胸甲裤子和鞋子的盔甲值

MC护甲属性是通过访问ItemArmor类的damageReduceAmount属性实现的，在编译之后是field_77879_b

由于护甲值计算仅在服务端执行，需要添加数据包同步到客户端才能在玩家界面正确显示。

    private int armorValue;  // 计算后的护甲值
    
    // 客户端收到后通过反射修改护甲值字段
    @SideOnly(Side.CLIENT)
    public IMessage onMessage(ArmorValueSyncPacket m, MessageContext ctx) {
        // ... 反射修改 field_77879_b
    }
}
