Melee Hit Chance is a stat: Chance to hit a target in melee. The target can still dodge even if we would've hit. Its minimum allowed value is 0%. Its default value is 0%.[1]
Calculation
Base score
The base score starts at 0 and is affected by the following things:
- Melee skill: +1 per level. For pawns without skills (e.g. animals): +4
- Sight: 12x importance, no allowed defect. 150% limit
offset = 12 x ((IF sight < 150% THEN sight ELSE 150%) - 100%)
e.g. +6 at 150% sight.
- Manipulation: 12x importance, no allowed defect. 150% limit
offset = 12 x ((IF manipulation < 150% THEN manipulation ELSE 150%) - 100%)
e.g. +3 at 125% manipulation.
- Brawler trait: +4
- Melee specialist role : +7
- Melee specialist's Beserk Trance : +8
- Leader's Combat Command : +3
- Mechlord suit : −0.5
- Mechlord helmet : −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.

External offset
The combat in darkness precept offsets the melee hit chance based on the light level of the targeted pawn (not the attacking pawn!) by −10 (lit) to +10 (dark)[Details needed]. 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 melee skill and the brawler trait results in the following melee hit chance:

Version history
- 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. Note: Default hit chance is 0.6 for pawns without skills. This equals the chance of a pawn with melee skill 6. (This has been reverted again at some point.)
