Breaking and Entering

Smashing an Object

Attacking an inanimate, immobile object not in use by a character does not provoke an attack of opportunity.

Armor Class

An inanimate, immobile object has an AC of:

10 - 5 for no Dexterity + its size modifier.

Immobile objects are easy to hit. With a melee weapon, the character gets a +4 bonus to the attack roll. If a character takes a full-round action to line up a shot (as with the coup de grace against a helpless foe), the character gets an automatic hit with a melee weapon and a +5 attack bonus with a ranged weapon.


Each object has hardness—a number that represents how well it resists damage. Whenever an object takes damage, subtract its hardness from the damage. Only damage in excess of its hardness is deducted from the object's hit points.

Hit Points

The amount of damage that an object can withstand depends on what it is made out of and how big it is. Weapon damage is rolled normally against objects.

An object's hit point total depends on what it is made of and how big it is. When an object's hit points reach 0, it's ruined. Very large objects have separate hit point totals for different sections.

Energy Attacks

Objects take half damage from acid, fire, and lightning attacks. Divide the damage by 2 before applying the Hardness. Cold attacks deal one- quarter damage to objects. Sonic attacks deal full damage to objects.

Ranged Weapon Damage

Objects take half damage from ranged weapons (except for damage from siege engines and the like). Divide the damage by 2 before applying the object's Hardness.

Ineffective Weapons

The DM may determine that certain weapons just can't deal damage effectively to certain objects. For example, a combatant will have a hard time chopping down a door by shooting arrows at it or cutting a rope with a club.


Inanimate objects are immune to critical hits. Objects are immune to subdual damage. Animated objects are immune to critical hits because they are constructs.

Magic Armor, Shields, and Weapons

The attacker cannot damage a magic weapon or shield that has an enhancement bonus unless his own weapon has at least as high an enhancement bonus as the weapon or shield struck. Each +1 of enhancement bonus also adds 1 to the weapon's or shield's Hardness and hit points. If a combatant's shield has a +2 enhancement bonus, a combatant add 2 to its Hardness and to its hit points.

Vulnerability to Certain Attacks

The DM may rule that certain attacks are especially successful against some objects. For example, it's easy to light a curtain on fire or rip up a scroll.

Saving Throws

Unattended nonmagical items never make saving throws. They are considered to have failed their saving throws, so they always are affected by (for instance) a disintegrate spell. An item attended by a combatant (being grasped, touched, or worn) receives a saving throw just as if the combatant herself were making the saving throw.

Magic items always get saving throws. A magic item's Fortitude, Reflex, and Will save bonuses are equal to 2 + one-half its caster level. Attended magic items either make saving throws as their owner or use their own saving throws, whichever are better.

Animated Objects

Animated objects count as characters for AC purposes.

Breaking Items

When a combatant tries to break something with sudden force rather than by dealing regular damage, use a Strength check to see whether the combatant succeeds. The DC depends more on the construction of the item than on the material.

If an item has lost half or more of its hit points, the DC to break it drops by 2.

*Break DC: The DC for a Strength check needed to destroy the item in one action, rather than reducing it to zero hit points through a series of attacks.

Table: DCs to Break or Burst Items

A common use of Strength is to break open doors and burst bonds. Larger and smaller creatures get size bonuses and size penalties on these Strength checks: Fine –16, Diminutive –12, Tiny –8, Small –4, Large +4, Huge +8, Gargantuan +12, Colossal +16.
