基本上任何打hp的魔法都能损坏物品
Energy Attacks: Acid and sonic attacks deal damage to most objects just as they do to creatures; roll damage and apply it normally after a successful hit. Electricity and fire attacks deal half damage to most objects; divide the damage dealt by 2 before applying the hardness. Cold attacks deal one-quarter damage to most objects; divide the damage dealt by 4 before applying the hardness.
Ranged Weapon Damage: Objects take half damage from ranged weapons (unless the weapon is a siege engine or something similar). Divide the damage dealt by 2 before applying the object’s hardness.
Ineffective Weapons: Certain weapons just can’t effectively deal damage to certain objects.
Immunities: Objects are immune to nonlethal damage and to critical hits.
Even animated objects, which are otherwise considered creatures, have these immunities because they are constructs.
Magic Armor, Shields, and Weapons: Each +1 of enhancement bonus adds 2 to the hardness of armor, a weapon, or a shield and +10 to the item’s hit points.
Vulnerability to Certain Attacks: Certain attacks are especially successful against some objects. In such cases, attacks deal double their normal damage and may ignore the object’s hardness.
这规则在什么情况下要用到呢，比如冰锥火球，的确会伤到范围内的无主物品。但它们通常只是背景，不视为有效的攻击对象。而若你缴械了敌人的武器想接一发火球把它毁掉，这是可行的。
至于箭穿火墙的问题，首先近战武器可以无损穿过不用投豁免，没啥道理常识可讲。既然如此，我觉得远程武器也应该一样，纯粹是公平起见。
