ASPDhttps://irowiki.org/wiki/ASPD

Attack Speed is abbreviated as ASPD. It depends on the player's class, equipped Weapon Type, Speed Modifiers, AGI and DEX.

• 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.

Each class has a Base ASPD (146 ~ 158) 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 ]

Note: Non-percentage numbers are absolute modifiers. These ones are directly added to the ASPD at the end of the calculations.
