====== Darkness ======

Darkness is a battlefield modifier that can be applied in a lot of ways. Its base effect is to decrease [[attack]], [[defence]] and [[precision]] of units, as it becomes harder to hit someone with your sword, dodge blunt objects or aim an arrow without the ability to see them. Different ways of generating darkness will have different magnitude of penalties, ranging from -1 to -6. 

Based off their abilities, units interact differently with it, some units going as far as ignoring the penalties entirely. As such, fighting in the dark can massively favor one side of a battle. Ways to generate darkness can be a significant force multiplier and research goal during the midgame. 

==== Interacting with darkness ====

  * Units with {{:abilities:darkvision.png?15}} [[Darkvision]] will suffer reduced penalties. 
  * Units with {{:abilities:spirit_sight.png?15}} [[spirit-sight|Spirit Sight]] will ignore darkness penalties. 
  * Units that are already {{:abilities:blind.png?15}}[[Blind]] will not suffer additional penalties for fighting in the dark. 
  * Units with {{:abilities:dark_power.png?15}}[[Dark Power]] will get a bonus to their stats when fighting in the dark. 

==== Ways to get darkness ==== 
=== Battlefield magic ===
  * The eponymous spell ??Darkness??, accessible after researching Alteration 6 and castable by a {{path>D4}} mage, will turn any battlefield into a dark room (-6 stat penalty).
  * ??Solar Eclipse?? is a less effective (-3) variant, requiring Alteration 5 and a {{path>F3S1}} caster. 

=== Global enchantments ===
  * The [[global enchantment]] ??Dark Skies?? will slightly (-1) darken battles in its owner's dominion. 
  * The [[global enchantment]] ??Utterdark?? will massively (-6) darken battles for everyone. 
  * ??Theft of the Sun??, a national [[global enchantment]] exclusive to [[xibalba-ea|EA Xibalba]]. 

=== Nature ===
  * [[province-attributes|Caves]] and [[province-attributes|Deep Seas]] already come with built-in darkness (at -3). 
  * Fighting at night, which is 50% of [[assassination]] battles, will cause -3 stat penalties. 

==== Ways to counter darkness ==== 
  * ??Solar brilliance?? undoes any darkness effect. It will also cause stat penalties to units with {{:abilities:dark_power.png?15}}[[Dark Power]]. 
  * Appropriately, getting a replacement ??Second Sun?? will undo the effects of ??Theft of the Sun??.
