Attack speed

From Fire Emblem Wiki, your source on Fire Emblem information. By fans, for fans.
Marth's attack speed exceeds the enemy Fighter's attack speed enough to allow him to perform a follow-up attack.

Attack speed (Japanese: 攻撃速度 attack speed), abbreviated AS (Japanese: 攻速), is a calculation based on a unit's speed which acts as their practical speed stat in battle. In all games until Fire Emblem: Shadow Dragon, attack speed factors in the weight of a unit's weapon, simulating the bulk of heavier weapons encumbering them in battle more than lighter weapons, with the effect thereof in turn mitigated by a unit's strength or physical bulk in games from Thracia 776 onward.

The primary use of attack speed is to determine whether or not a unit is fast enough compared to their opponent to allow them to perform a follow-up attack (Japanese: 追撃 pursuit), more commonly known as "double attacking" or "doubling". In a battle, the two participants' mutual attack speed is compared, and if one unit meets a certain threshold of higher attack speed than the other, they are allowed to follow up against the opponent: to perform a second attack after both units have performed their first attacks.

Attack speed is also used in turn in a unit's avoid calculation, directly impacting a unit's ability to dodge oncoming attacks in conjunction with other factors, including terrain benefits and a unit's luck stat.

From New Mystery of the Emblem through Fates, weapon weight has been removed and attack speed is now calculated solely based on the speed of the two units. However, Fates introduced numerous weapons and skills which directly give boosts and reductions to their user's attack speed.

Fates includes a similar mechanic known as effective speed. Unlike attack speed, effective speed only affects follow-up attacking, and can be one-sided. For example, steel weapons affect the wielder's ability to double but not their ability to be doubled, and certain weapons such as Excalibur raise the wielder's ability to double but also raise their ability to be doubled.

Trivia

  • Attack speed does not technically exist in Fire Emblem Gaiden and Fire Emblem Echoes: Shadows of Valentia, with weapon weight being a straight penalty to the user's speed stat.
  • In Fates, due to the "effective speed" system, it is possible to create a situation where both the attacker and the defender double attack each other in a single round of combat. The weapons Excalibur, Chakram, and Pursuer boost both the user's and the opponent's ability to double attack by +5, so if the attacker and defender have the same speed and one of them is wielding one of these weapons, they will double each other.
