Blind Fight
From NWN2Wiki
Type of feat: General
Prerequisite: None
Required for: None
Specifics: This feat grants the character the ability to fight well if blinded or against invisible creatures. The character gets to re-roll its miss chance percentile one time to see if it actually hits.
A fighter may select blind fight as one of his fighter bonus feats. Clerics with the Darkness domain receive this feat for free at first level. Red Dragon Disciple receives this feat for free at 5 class levels. Yuan-ti receive blind fight for free at creation.
Use: Automatic
Note: Blind Fight does not change the targets concealment, but instead gives a second roll if you miss due to concealment. The probability of missing a target with 50% concealment changes from 50% to 25%, due to having to fail both rolls (0.5*0.5=0.25). Similarly, if a target has 10% concealment (e.g. from Ghostly Visage), to miss said target one would have to fail both rolls, which has a a probability of 0.1*0.1=0.01, or 1%.
Essentially, the probability of a character with blind fight missing a target due to concealment is the square of the probability that a character without blind fight would miss a target due to concealment.

[edit] PNP Comparison
The +2 bonus to hit that invisible creature should have against a sighted opponent was never implemented in NWN2, so there is no damage bonus which the feat negates. The in game description was copied from the PnP source.
