Ragnarok Renewal Attack Speed

Disable in Supreme Ragnarok Reborn

Attack Speed Renewal

The maximum possible ASPD value is 193 for characters over level 100, and 190 for characters below level 100.

The amount of hits your character makes is calculated as such: 
50 / (200-FinalASPD) hits per second
Which means, a character with 193 ASPD will do 50/7 = 7.14 attacks per second.


ASPD formula is based on KRO, which is very different from iRO’s formula. You can expect to find it somewhat more difficult to attain higher ASPD here.A Character’s ASPD is calculated as follows:

Which takes these following parameters into account:

  • Base ASPD: A base number determined by the character’s class.
  • Weapon/Shield Penalty: A penalty based on the character’s class and the weapon/shield being equipped.
  • Stat Bonus: bonus based on a Character’s AGI and DEX.
  • Status Bonus: bonuses from status effects bestowed by ASPD potions and certain skills.
  • %ASPD: Percentage bonuses from certain skills, items and equipments such as 60.png Two-Hand Quicken, Enriched Celermine Juice and  Cenere Card.
  • Flat Bonus: bonuses in the form of flat additions gained from certain equipment.

The Stat ASPD bonus is calculated differently depending on weapon type:
