Overview
Attack Speed is abbreviated as ASPD. It depends on the player's class, equipped Weapon Type, Speed Modifiers, AGI and DEX.
Factors affecting Attack Speed
 The player's class.
 The player's weapon type.
 Increasing AGI to gain higher Attack Speed. (DEX provides negligible Attack Speed increases)
 Wearing a shield decreases Attack Speed. The difference varies by class and is more dramatic at higher base Attack Speeds.
 Some items, skills and equipments can either increase or decrease Attack Speed.
ASPD Formula
Each class has a Base ASPD (146 or 156) which is affected by the weapon (50 ~ +2). Equipping a shield reduces ASPD by 5 ~ 10.
ASPD Penalty = [ 1 − { Job Base ASPD − 144 } ÷ 50 ]
 Note: Limit down to a maximum of 0.96. Keep 2 decimals.
ASPD Correction = [ { √( 205 ) − √( AGI ) } ÷ 7.15 ]
 Note: Round up to 3 decimals.
Equip ASPD % = [ { 195 − Base ASPD } × Total of Equip ASPD Mod ]
 Note: Round down to 1 decimal.
Base ASPD = [ 200 − { 200 − ( Job Base ASPD + Shield Penalty − ASPD Correction + √[ AGI × 9.999 + DEX × 0.19212 ] × Aspd Penalty ) } × { 1 − Potion ASPD Mod − Skill ASPD Mod } ]
 Note: Round down to 2 decimal.
Final ASPD = [ Base ASPD + { Equip ASPD % } + Equip ASPD Fixed ]

Hits per Second
Hits/sec. =
 [ 50 ÷ ( 200 − Final ASPD ) ]
 [ 50 ÷ Delay ]
 [ 1 ÷ Time Between Attacks ]
ASPD represents Attack Speed as a hyperbolic function (different from exponential function) that approaches infinite hits per second as ASPD gets close to 200.
