====== Shield ======
Some units wear a shield. A shield helps protect the wearer vs both melee and ranged attacks. All shields have a Parry value and a [[Protection]] value. The Parry value determines how easy it is to parry attacks with the shield. The Protection value indicates how much Protection the shield offers on a succesful parry. How it affects the wearer depends on the type of attack.

===== Shields in Melee Combat =====
In melee combat a shield adds extra [[Protection]] to any defender who succesfully parries a melee attack.

<WRAP box round 800px center>==== Melee To Hit Roll (Shield) ====
<WRAP column half>
**Attack roll:** Weapon's Attack value \\ + [[melee-roll#Attack modifiers|Attack modifiers]], if any \\ + [[DRN]]
</WRAP><WRAP column half>
**Defense roll:** Defender's Defense value  \\ + [[melee-roll#defense modifiers|defense modifiers]], if any \\ + [[DRN]] \\ **+Shield Parry rating**
</WRAP>
<WRAP centeralign>If Attack roll > Defense roll + Parry rating => Attack hits as normal \\
If Defense roll + Parry >= Attack roll > Defense roll => Attack is Parried \\
If Attack roll =< Defense roll => Attack misses</WRAP></WRAP>

When an attack is Parried the shield's Protection is subtracted from the damage roll. 
  * This added Protection is not affected by diminishing return like normal Protection. 
  * It is still affected by the Protection reduction from piercing and [[armor piercing]] attacks like any other attack.
===== Shields in Ranged Combat =====
In ranged combat a shield can protect against incoming damage.
<WRAP box round 800px center>==== Shields in Ranged Combat ====
<WRAP column half>
**Attack roll:** [[Size]] points in the square \\ +2 if [[magic weapon]] \\ + [[DRN]]
</WRAP><WRAP column half>
**Defense roll:** 2  \\ – [[Fatigue]] / 20 \\ + [[DRN]] \\ **+ Shield Parry value x2**
</WRAP>
<WRAP centeralign>If Attack roll > Defense roll + Parry rating => Attack hits as normal \\
If Defense roll + Parry >= Attack roll > Defense roll => Attack is Parried \\
If Attack roll =< Defense roll => Attack misses</WRAP>
</WRAP>

When an attack is Parried the shield's Protection is subtracted from the damage roll. 
  * This added Protection is not affected by diminishing return like normal Protection. 
  * It is affected by [[armor piercing]] reduction to Protection like any other attack. 
  * However testing has shown that it //is not// affected by the armor reduction from piercing attacks.
===== Shield destruction =====

Shield hits can damage or destroy the shield. A shield has a Resistance, which is the same as its shield protection value, +5 if the shield is a magic one. The attack has a Break value, which is equal to the damage of the attack before any Protection.

Note that many spells have the [[Ignores Shields]] tag which basically means that shields will have no influence at all against that particular attack.

<WRAP box round 800px center>==== Rolling for Shield Destruction ====
<WRAP column half>
**Break value:** Damage of attack before reduction </WRAP><WRAP column half>
**Shield Resistance** Shield Protection value +5
</WRAP><WRAP centeralign>
If the Break value is **>= 3x** the Shield Resistance, the shield is **damaged** (-20% Prot). \\
If the Break value is **>= 5x** the Shield Resistance, the shield is **broken** (-50% Prot). \\ \\
An already **damaged** shield that is damaged again has a 25% chance of being **broken**.

Damaged shield protection values round down: that is to say that a damaged ??Scutata Volturnus?? offers 16 Protection.

A magic shield (a real, equipable one) that is damaged will repair itself after the battle. If a magic shield is broken, it will be permanently destroyed and the commander will revert to his or her standard shield if he or she had one. Damaged or broken mundane shields will be repaired when they are in a province with enough spare production resources.
