Damaging Objects
When damaged, objects don't bleed out a pool of hit points. Instead they weather, warp, and splinter under the steady creep of Riven. Whenever a spell, trap, or weapon deals ordinary hitpoint damage to gear, the total is simply converted into Riven (see below). Colossal subjects such as walls, ships, or keeps follow the dedicated Structural Damage rules instead, but everything from a glass vial to a gilded greatsword uses the guidelines below.
Attacks on Objects
When an attack can target an object, first decide whether the item is attended (worn, carried, or actively controlled) or unattended (lying loose, fixed in place, or otherwise not in a creature's care). Objects are Mindless and usually ignore any attack that requires a Will defense. They also ignore status effects that have no meaning for inanimate matter (for example, Dazed, Frightened, or Dominated).
Attended Objects
An attended object—anything a creature is wearing, holding, or otherwise directly controlling—uses that creature's defenses to resist the attack roll. If the effect requires a Saving Throw, the creature rolls for it using its own scores and rules regarding saving throws (i.e. a simple vs complex creature). The creature may roll saves for the object whenever it would normally be allowed to make a saving throw, such as by taking the Recovery Action or receiving an Aid effect.
Unattended Objects
An unattended object relies only on its material sturdiness. It has Defense scores of 8 and uses a score of -2 whenever making an opposed roll. The object automatically fails all saving throws, although a save-ends effect still ends after 1 moment. Once a creature picks up or otherwise takes control of the item, it becomes attended, and the creature may begin making saving throws for it.
Objects in Area Effects
When a power targets all creatures and objects within an area, only unattended objects are targeted by the attack. Any item a creature is wearing, wielding, or carrying is treated as part of that creature and is completely ignored by the power. It cannot be chosen as a target, does not receive a separate attack roll, and suffers no damage, Riven, or other effects from the area effect.
Converting Hitpoint Damage to Riven
When a power targets an object but only deals hitpoint damage, divide the total damage by 10 (rounding down). That is how much Riven is potentially inflicted upon the object. Subtract the object's Hardness as normal and apply the remaining Riven (if any) to the object. Some objects have negative Hardness and take additional Riven when dealt damage, even when the base amount of Riven is 0.
