-**Protection** is a property of units that reduces damage that they take from most attacks. It is generally provided from either manufactured armor or from natural protection (tough skin, scales, being made of stone, etc.) If a unit has both manufactured armor and natural protection, their values stack with diminishing returns. +**Protection** is a property of units that reduces damage that they take from most attacks.

 Since manufactured armor provides protection, the increasing technology level in Middle and Late Age means that most national and [[independent]] troops tend toward higher and higher protection values in later ages. Since manufactured armor provides protection, the increasing technology level in Middle and Late Age means that most national and [[independent]] troops tend toward higher and higher protection values in later ages.

 Protection is tracked separately for the head and body of units. Natural protection protects both locations; manufactured armor counts separately for each. For instance, chain mail protects the body but not the head, and a helmet protects the head but not the body. Protection is tracked separately for the head and body of units.

 Shields also have a protection value. If a unit has a shield, any hit to the shield results in the shield's protection value being added (without diminishing returns).

 Protection amounts to a flat subtraction from the damage dealt by most attacks. High protection values can thus make a unit nearly immune to weak attacks, requiring a lucky DRN role to overcome; units with low protection values are vulnerable to large numbers of weak attacks, particularly arrows. Protection amounts to a flat subtraction from the damage dealt by most attacks.

 +The ??Legions of Steel?? spell ([[Construction]] [[Research|3]], {{path>E3}}, 40 Fatigue) increases the Protection value of each piece of Armor worn by a large group of troops by 3.

-Several spells increase the base natural protection of targets, but make them more vulnerable to certain sorts of magic:+  * **Barkskin** increases Natural Protection to 10, or by +1 if it is already ten or higher, but confers 5 points of Fire Vulnerability. The ??Barkskin?? spell (Alteration 1, {{path>N1}}, 5 Fatigue) applies it to the caster, ??Protection?? (Alteration 3, {{path>N1}}, 20 Fatigue) applies it to troops in a single square, ??Wooden Warriors?? (Alteration 5, {{path>N2}}, 50 Fatigue) applies it to troops in five squares, and ??Mass Protection?? (Alteration 7, {{path>N3}}, 100 Fatigue and {{gems>1N}}) applies it to your whole army. There's also the Barkskin [[Bless]], which applies Barkskin to [[Sacred]] units when they're blessed, and requires {{path>N6}} in bless points during [[Pretender| Pretender design]]. 
 +  * **Stoneskin** increases Natural Protection to 15, or by +2 if it is already 14 or higher, but confers 5 points of Cold Vulnerability. The ??Stoneskin?? spell (Alteration 2, {{path>E1}}, 10 Fatigue) applies it to the caster, while ??Marble Warriors?? (Alteration 7, {{path>E3}}, 100 Fatigue and {{gems>1E}}) applies it to troops in twenty-five squares. 
 +  * **Ironskin** increases Natural Protection to 20, or by +3 if it is already 18 or higher, but confers 5 points of Shock Vulnerability. The ??Ironskin?? spell (Alteration 3, {{path>E1}}, 20 Fatigue) applies it to the catser, ??Iron Warriors?? (Alteration 5, {{path>E2}}, 40 Fatigue) applies it to troops in a single square, and ??Army of Gold?? and ??Army of Lead?? (Alteration 9, {{path>E5}}, 300 Fatigue and {{gems>3E}}) apply it to your whole army; Army of Gold also applies 5 points of Fire Resistance, while Army of Lead boosts Magic Resistances by 4 instead.

(Alteration 5; Nature 2, 50 fatigue) grants Barkskin to a group of troops, and ??Mass Protection?? (Alteration 7; Nature 3, 100 fatigue, 1 Nature gem) grants it to a whole army. +These three effects do not [[stacking-effects|stack]]; only whatever was applied most-recently has an effect.
-  * ??Stoneskin?? (Alteration 2; Earth 1, 10 fatigue) increases natural protection to 15, or by +2 if it is already 14 or higher, but confers cold vulnerability. ??Marble Warriors?? (Alteration 7; Earth 3, 100 fatigue, 1 Earth gem) grants Stoneskin to a group of troops. +

-=== Dealing with high protection ===+==== Dealing with high protection ====
  
 One option for dealing with high protection units is to simply hit them harder; many nations have or can summon troops with two-handed weapons who are good at this. Many forged weapons provide very high damage values and/or AP or AN attacks; these can be useful in breaking through exceptionally high protection values on immobile pretender gods and some [[supercombatants]]. The most accessible of these is ??Greatsword of Sharpness??. One option for dealing with high protection units is to simply hit them harder; many nations have or can summon troops with two-handed weapons who are good at this.
