STR - VIT Difference Function

(Redirected from FSTR)

fSTR[edit]

fSTR is the damage bonus/penalty from your STR - monster VIT for melee attack

  • Melee attacks need roughly 4~6 STR to increase fSTR value by 1.
  • When STR-VIT value is high, fSTR can be approximated by ((your STR - monster VIT)+4)/4.
  • fSTR's lower and upper cap values are affected by weapon rank.
The lower cap of fSTR is - Weapon Rank
Exception: Rank 0 weapons have lower cap -1.
The upper cap of fSTR is ( weapon rank+8).

Example:

Juggernaut is a rank 5 weapon (int(46/9) = 5). Therefore the possible fSTR value of Juggernaut ranges from -5 to 5+8=13.


fSTR2[edit]

fSTR2 is the damage bonus/penalty from your STR - monster VIT for ranged attack.

  • It takes roughly 2~3 more STR to increase fSTR2 by 1 depending on how big your STR - mob VIT value is.
  • When STR-VIT value is high, fSTR2 can be approximated by (your STR - monster VIT+4)/2 and
  • fSTR2's lower and upper cap values are affected by weapon rank.
The lower cap of fSTR2 is - (Weapon Rank) x 2.
Exceptions:
Rank 0 weapons have lower cap -2.
Rank 1 weapons have lower cap -3.
The upper cap of fSTR2 is ( weapon rank+8) x 2.

Example:

Hellfire +1 is a rank 4 weapon (int (42/9) = 4). Therefore the possible fSTR2 value of Hellfire+1 ranges from -4x2= -8 to (4+8)x2 = 24.


fSTR(2) Approximation Table[edit]

fSTR and fSTR2 can be approximated using the following table.
In table below, dSTR(delta strength) value denotes your STR - monster VIT.

The table[edit]

dSTR range fSTR approximation fSTR2 approximation
12 or greater (dSTR + 4) / 4 (dSTR + 4) / 2
6 to 11 (dSTR + 6) / 4 (dSTR + 6) / 2
1 to 5 (dSTR + 7) / 4 (dSTR + 7) / 2
-2 to 0 (dSTR + 8) / 4 (dSTR + 8) / 2
-7 to -3 (dSTR + 9) / 4 (dSTR + 9) / 2
-15 to -8 (dSTR + 10) / 4 (dSTR + 10) / 2
-21 to -16 (dSTR + 12) / 4 (dSTR + 12) / 2
-22 or less (dSTR + 13) / 4 (dSTR + 13) / 2
