Skill (stat)

Skill increases a unit's Hit percentage and Critical rate. It also increases the chances of activating special skills such as Lethality and Aether in certain games.

A Secret Book can be used to increase a unit's skill, although the number of stat-increasing items that can be used in any game is limited. This being the case, Secret Books are usually given to those units who have low skill normally, such as axe-fighters.

To calculate the chance of a critical, the formula below is usually as follows:

Unit's Skill / 2 + weapon critical chance + support bonus (if any) + the class critical bonus or skills (if any) - the enemy's luck + 5% (if a character has a S-rank in Fire Emblem: Rekka no Ken or Fire Emblem: The Sacred Stones only)

The only Fire Emblem game in which units could not reach 100% critical is Fire Emblem: The Sacred Stones.
