== Shield ([[SRD:Special Abilities Overview#Extraordinary|Ex]] or [[SRD:Special Abilities Overview#Supernatural|Su]]) ==
Shield is a protection unique to certain creatures, most of which are [[SRD:Construct Type|constructs]]. [[Summary::A shield defends the creature it envelopes and has the ability to soak damage of most any kind.]] For every [[SRD:Hit Dice|HD]] a creature has, the shield that protects it has 5 [[SRD:Hit Points|hit points]]. Shield hit points are generally regained at a rate of 1 hit point per [[SRD:Hit Dice|HD]] per minute.
Shields that are technological in nature, such as those belonging to [[SRD:Construct Type|constructs]] are most often [[SRD:Special Abilities Overview#Extraordinary|extraordinary]] in nature, whereas the shields of magical creatures and those granted by magic spells and items such as [[Shield Talisman, Lesser (3.5e Equipment)|shield talismans]] are considered [[SRD:Special Abilities Overview#Supernatural|supernatural]], and can be suppressed in an ''[[SRD:Antimagic Field|antimagic field]]''.
As long as a shield has [[SRD:Hit Points|hit points]] remaining, any damage done to the protected creature is dealt to the shield instead. A shield can absorb damage of virtually any kind, from physical damage types ([[SRD:Bludgeoning Weapon|bludgeoning]], [[SRD:Piercing Weapon|piercing]], [[SRD:Slashing Weapon|slashing]]) to energy damage types ([[acid]], [[cold]], [[electricity]] and [[fire]]), to [[SRD:Force Effect|force damage]], to even most typeless forms of damage. Shields are even effective against [[SRD:Touch Attack|touch attacks]]. A shield can never absorb more damage than that it has [[SRD:Hit Points|hit points]] remaining, and any damage over that amount is dealt to the protected creature.
An active shield with 1 or more [[SRD:Hit Points|hit points]] grants immunity to [[SRD:Critical Hits|critical hits]] to any creature or object it protects.
=== {{Anchor|Perimeter Shield}} === Certain creatures and objects possess shields that protect an area around them. As long as the shield has [[SRD:Hit Points|hit points]] remaining, it stops objects and energy outside it from passing through, like a ''[[SRD:Wall of Force|wall of force]]'', decreasing its [[SRD:Hit Points|hit points]] by the appropriate amount. Objects and energy coming from inside the perimeter shield can pass through unimpeded. Effects that can pass through shields can also pass through perimeter shields (like [[SRD:Sonic Effect|sonic]] energy). If the damage caused to the perimeter shield by an area effect breaks through it, the area effect may continue beyond the perimeter shield if the area permits; otherwise its expansion is stopped at the edge of perimeter shield. In the case of an area effect caused by an explosive effect, like a ''[[SRD:Fireball|fireball]]'' or an acid flask, the explosive projectile detonates upon impact with the shield. Regardless, the center of an explosive effect lies outside the perimeter shield. The effective [[SRD:Armor Class|AC]] of the perimeter shield itself is 15 plus the [[SRD:Deflection Bonus|deflection]] bonus it grants. Attacks originatig from outside the perimeter shield cannot directly target a creature inside it until the shield is down. Such attacks are resolved with the shield itself as the target. Perimeter shields are projected as a spherical field around their source. A perimeter shield does not extend into floors or walls. The radius of the shield is listed in the object or creature's description. A perimeter shield blocks line of effect (except that of [[SRD:Sonic Effect|sonic]] effects) provided it has at least 1 [[SRD:Hit Points|hit point]], but not line of sight. === {{Anchor|Hard Shields}} === A few special creatures and objects have very powerful shields that can absorb a certain amount of damage from an attack without weakening, making even shields with a low amount of [[SRD:Hit Points|hit points]] hard to break through. These shields have a set [[SRD:Breaking and Entering#Hardness|hardness]], subtracting that number from any damage the shield takes, to a minimum of 0. This particular property can be added to any type of shield. === Special Shield Types === Some forms of shielding have special properties. Specialized types of shields only block specific effects or specific forms of damage. A shield can have only a single specialized type. ==== {{Anchor|Kinetic Shield}} {{Ex}} ====
Kinetic shields are shields that only stop high-speed physical projectiles. The stopping power of a kinetic shield is dependent on the speed of the object hitting it, providing a degree of deflection correspondent to the momentum of the object. The result is a shield that stops fast moving objects like weaponsfire but has no effects on slow moving objects, allowing the creature to interact with its environment without deflecting it.
Objects stopped by a kinetic shield include high speed objects and projectiles. Weapons such as handguns and rifles, cannons and particle beams are stopped, but lasers, energy effects and other massless or incorporeal weapons are not. Melee attacks are not stopped by a kinetic barrier, nor are slow-moving ranged attacks such as arrows or thrown projectiles.
Kinetic shields are a usual staple of science-fiction and are always [[SRD:Special Abilities Overview#Extraordinary|extraordinary]] in nature.Shields can only emulate a single type
==== {{Anchor|Spell Shield}} {{Su}} ====
Spell shields are do not stop damage in the way normal shields that do. Instead, they absorb incoming spells, either in addition to or instead of regular damage. Whenever a creature or object protected by a spell shield is targeted by a harmful spell, the spell is reduced to its base components upon touching the shield, converting it to raw energy that deals 5 damage to the shield per converted spell level. Spells that create area effects are only absorbed for the creature or within the area that a spell shield protects. If a creature has [[SRD:Spell Resistance and Spell Immunity#Spell Resistance|spell resistance]], the spell shield takes effect against a spell only if the creature fails to resist it. Spells that do not allow spell resistance are not absorbed by a spell shield.
Spells absorbed by a spell shield deal 1 extra point of damage per spell level if the spellcaster has the [[SRD:Spell Penetration|Spell Penetration]] feat, and 2 extra points of damage per spell level if the spellcaster has the [[SRD:Greater Spell Penetration|Greater Spell Penetration]] feat.
 
Damage dealt to a spell shield over its remaining hit points are not dealt to the protected creature. Instead, if the shield is a permanent ability, the shield maintains its negative hit points and remains down until its hit points are restored to positive values by the shield's natural recovery.
Spell shields are always [[SRD:Special Abilities Overview#Supernatural|supernatural]] in nature.
==== {{Anchor|Perimeter Psi-Shield}} {{Su}} ====
Certain creatures and objects possess Psi-shields that protect an area around them. As long function the same way as the shield has [[SRD:Hit Points#Spell Shield|hit pointsspell shields]] remainingdo, it stops objects and energy outside it from passing through, like a ''except in that they absorb incoming psionic [[SRD:Wall of ForcePowers|wall of forcepowers]]'', decreasing its instead of spells. Powers that do not allow [[SRD:Hit PointsPower Resistance|hit pointspower resistance]] are not absorbed by the appropriate amount. Objects and energy coming from inside the perimeter a psi-shield can pass through unimpeded. Effects that can pass through shields can also pass through perimeter shields (like [[SRD:Sonic Effect|sonic]] energy).
If the damage caused to the perimeter shield by an area effect breaks through it, the area effect may continue beyond the perimeter shield if the area permits; otherwise its expansion is stopped at the edge of perimeter shield. In the case of an area effect caused by an explosive effect, like a ''[[SRD:Fireball|fireball]]'' or an acid flask, the explosive projectile detonates upon impact with the shield. Regardless, the center of an explosive effect lies outside the perimeter shield.==== Other Shield Types ====
The effective [[SRD:Armor Class|AC]] of the perimeter shield itself is 15 plus the [[SRD:Deflection Bonus|deflection]] bonus it grantsSpecialized shields exist for many purposes. Attacks originatig from outside the perimeter shield cannot directly target Creatures that only need protection against a creature inside it until the shield is down. Such attacks single type of effect do not need universal shields, that are resolved with the shield itself as the targetusually prohibitively expensive, difficult to maintain and especially powerfulPerimeter Possible types of shields specialized to a single group of effect types are projected as listed below, complete with a spherical field around their source. A perimeter shield does not extend into floors or walls.
