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.
