Accuracy

Accuracy represents the probability of an attacking unit landing a successful hit on a defending unit. It is a percentage that is influenced by various factors, such as the attacking unit's hit rate or the defending unit's evade.

Overview

Accuracy percentages are determined by various internal (e.g., hit rate, evade) and external factors (e.g., weapon triangle effects) that influence a combative interaction between opposing units or groups of units. The sum of all applicable factors yield a value that is then converted into a percentage. This percentage—which is depicted as the battle accuracy—is then used as a threshold value for a successful hit or miss in a random number generator system.

In almost every Fire Emblem game, the accuracy sums below 0 are set to 0 and accuracy sums exceeding 100 are set to 100. In Fire Emblem: Thracia 776, the accuracy sums below 1 are set to 1 and accuracy sums exceeding 99 are set to 99.
