Avoid rate

Avoid rate (Avo) is a calculated stat in Fire Emblem: Redemption which reduces enemy Hit, and therefore lowers the chances that any attack they attempt will land. The Battle Forecast will not show your Avo; instead, it will subtract your Avo from the enemy's final Hit.

Each unit also has their own Avo value which can be viewed in their stats page. This value is equal to the unit's Spd*0.75 + their Luk*0.25 + the Avo of their equipped weapon. It does not take skills into account.

Note that a high Avo will not directly reduce the chances of the enemy landing a critical hit. Prt is used to reduce the chances that an enemy's successful attack will become a critical hit, whereas Avo is used to reduce the chances of the enemy landing any hit at all.
