ECO – Stats

July 6, 2009 at 11:11 pm 8 comments


In ECO, in addition to players’ appearances and skills (from jobs), the assignment of stat points contributes greatly to the development of a character. Depending on the type of character you wish to make, everyone will inevitably have different stat builds. There are 6 main stats: STR, DEX, INT, VIT, AGI, MAG. I will explain what each stat effects, outline the substats and describe status effects as well.


As you level, you get increasingly more points to assign to whichever stats you wish. You will be prompted to verify your assignment before confirming. By manipulating the main stats, you can see how the substats are affected. Note that it is possible to reset stats (at a cost of 1000G x BaseLv). So you don’t have to force yourself to think of stat builds. It’s just that I prefer to analyze mechanics ^^;;

For those who can read Japanese: ECO simulator

Equipment and skill-based stat modifications are added to the following formulas. For stat bonuses by main stat, refer to the JP ECO Wiki.

ATK (Melee attack power)

  • Min = floor[(STR + floor[STR/9]^2)*(1+modifier)]
    where modifier = floor[DEX*1.5]/160 for short range
    and modifier = floor[INT*1.5]/160 for long range
  • Max = STR + floor[(STR+14)/5]^2

M.ATK (Magic attack power)

  • Min = floor[(MAG + floor[(MAG+9)/8]^2)*(1+modifier)]
    where modifier = floor[INT*1.2]/320
  • Max = MAG + floor[(MAG+17)/6]^2

S.HIT (Short range accuracy)

  • DEX + floor[DEX/10]*11 + LV + 3

L.HIT (Long range accuracy)

  • INT + floor[INT/10]*11 + LV + 3

DEF (Defence)

  • floor[VIT/3] + floor[VIT/9]*2
  • Capped at 70

M.DEF (Magic defence)

  • floor[INT/3 + Vit/4]
  • Capped at 70

S.AVOID (Short range evasion)

  • AGI + floor[(AGI+18)/9]^2 + floor[LV/3] -1
  • Capped at 400

  • Capped at 400

A.SPD (Melee attack speed)

  • AGI*3 + floor[(AGI+63)/9]^2 + 129
  • Capped at 800
  • Attack speed = [Attack speed at A.SPD=0] * (1 – A.SPD/1000)

C.SPD (Magic cast speed)

  • DEX*3 + floor[(DEX+63)/9]^2 + 129
  • Capped at 800

  • Lower capped at 0.5s

HP (Hit point / Life)

  • floor[(VIT*3 + floor[VIT/5]^2 + LV*2 + floor[LV/5]^2 + 50)*modifier]
    where modifier is based on job (highest for fighters)

  • floor[(MAG*3 + LV + floor[LV/9]^2 + 30)*modifier]
    where modifier is based on job (highest for spellusers)

  • MP recovery based on MAG (bonus every 3)
  • SP recovery based on INT+VIT (bonus every 6)
  • Healing amount based on min M.ATK

Status Effects

    The stat system that allowed for customization was one of the things that made Ragnarok Online great.

    Reminds me of the good times, but I really wasn’t planning on playing MMOs again (too time consuming). Might try this out a bit though.

      Ya, I loved the customization in RO with all the different stat and skill builds.

      I wasn’t planning to play either, but I loved this game when I was playing the JP version. So it’s not ‘playing another MMO’. Wait… does that mean I relapsed? D:

  • 3. Verdeamia  |  July 6, 2009 at 11:32 pm

    Crazy Ari and your posting.

    • 4. Micchi  |  July 7, 2009 at 2:17 pm

      There’s more where that came from. Kekeke…

    well getting bored on OL games quite fast but ill have been checking this out from japan <_<

    Just a question about the stats. I take it that INT increases minimum ranged damage, but what raises maximum ranged damage?

    • 7. Micchi  |  July 24, 2009 at 1:21 pm

      STR increases max ranged damage.

      • 8. Mincemaker  |  July 25, 2009 at 3:33 am

        Ah, I see. Thanks for the info.
