== Calculation ==
=== Base score ===
The base score starts at 0 and is affected by the following things:
* [[Skills#Melee|Melee]][[Skill::Melee| ]] skill: {{+|1}} per level
* [[Sight]]: [[Sight Importance::12|12x]] importance,  no allowed defect. [[Sight Limit::1.5|150%]] limit
** <code>offset = 12 x ((IF ''sight'' < 150% THEN ''sight'' ELSE 150%) - 100%)</code> e.g. {{+|6}} at 150% sight.
* [[Manipulation]]: [[Manipulation Importance::12|12x]] importance,  no allowed defect. [[Manipulation Limit::1.5|150%]] limit
** <code>offset = 12 x ((IF ''manipulation'' < 150% THEN ''manipulation'' ELSE 150%) - 100%)</code> e.g. {{+|3}} at 125% manipulation.
* [[Brawler]] trait: {{+|4}}
* [[Ideoligion#Melee specialist|Melee specialist role]] {{IdeologyIcon}}: {{+|7}}
* [[Ideoligion#Melee specialist|Melee specialist's Beserk Trance]] {{IdeologyIcon}}: {{+|8}}
* [[Ideoligion#Leaders|Leader's Combat Command]] {{IdeologyIcon}}: {{+|3}}
* [[Mechlord suit]] {{BiotechIcon}}: {{--|0.5}}
* [[Mechlord helmet]] {{BiotechIcon}}: {{--|0.5}}

=== Post-processing curve ===
The ''melee hit chance'' is then calculated with the following ''post-processing curve''. As you can see increasing the ''base score'' has diminishing returns.

{| class="wikitable"
! Base score to Melee hit chance 
|-
| {{Graph:Chart
 | width = 300
 | height = 300
 | type = line
 | xAxisTitle = Base score
 | yAxisTitle = Melee hit chance
 | x =  -20, -10,   0,  10,  20,   40,   60
 | y = 0.05, 0.1, 0.5, 0.8, 0.9, 0.96, 0.98
 | yAxisFormat = %
 | yAxisMax = 1
 | xGrid = 10
 | yGrid = 0.1
 }}
|}

=== External offset ===
The [[combat in darkness]] precept {{IdeologyIcon}} offsets the ''melee hit chance'' based on the [[light|light level]] of the ''targeted'' pawn (not the attacking pawn!) by {{--|10}} (lit) to {{+|10}} (dark){{Check Tag|Details needed|Exact formula unclear. Probably linear from -10 at 0% light to +10% at 100% light.}}. Other than that the light level has no effect on the ''melee hit chance''.

== Examples ==
=== Melee skill and brawlers ===
Assuming no other offsets to the ''base score'', the [[Skills#Melee|melee]] skill and the [[brawler]] trait results in the following ''melee hit chance'':

== Version history ==
* [[Version/0.17.1546|0.17.1546]] - Removed post-process curve from melee hit chance so it uses the simple level-by-level tuning. It’ll be much harder to hit things now at low melee skills.
