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[edit]
Base score[edit]
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[edit]
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[edit]
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[edit]
Melee skill and brawlers[edit]
Assuming no other offsets to the base score, the melee skill and the brawler trait results in the following melee hit chance:

Version history[edit]
- 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.)
