Compilation of formulas and other mechanics.

Physical Damage

To calculate physical damage (meaning any damage not coming from a special attack or a technique), begin by calculating the equipment ATP:

EA = [WA + AA + ShA + Grind x 2] x [ATR + 1.0]

  • EA = Equipment ATP
  • WA = Weapon base ATP
  • AA = Armor ATP
  • ShA = Shield ATP
  • ATR = Weapon attribute %


Next, add the bonuses from shifta:

SA = [BA x Shifta] + [(MWA - MinWA) x Shifta]

  • SA = Shifta ATP
  • BA = base ATP
  • Shifta = Shifta Base Power (table below)
  • MWA = Maximum possible weapon ATP
  • MinWA = Minimum possible weapon ATP


To determine your final ATP, add your BA, EA, and SA together:

ATP = BA + EA + SA


Finally, to calculate your damage on a monster:

[(ATP - DFP)/5] x 0.9 = Weak/Base

  • Heavy: Base x 1.89
  • Sacrifice: Base x 3.32
  • Vjaya: Base x 5.56
  • Critical: Result x 1.5

Accuracy

Effective ATA = (Total ATA) * (Attack Type modifier) * (Combo Step modifier)

  • Attack Type modifier is 1.0 for Weak Attack, 0.7 for Heavy Attack, 0.5 for Special Attack
  • Combo Step modifier is 1.0 for first button press in combo, 1.3 for second, 1.69 for third.


Effective EVP = (Enemy EVP) * (Status Effect modifier)

Status Effect modifier is 0.85 if Paralyzed or Shocked, 0.7 if Frozen.


Accuracy = Effective ATA - (Effective EVP) * 0.2

  • Accuracy is further reduced by Distance*0.33 if it's a Hunter/Force without Smartlink.
  • Accuracy is further reduced by manual evasion, but the exact influence is unclear.

Technique Damage

Technique damage formula:

{[(MST + TBP)/5] x (1.0 + CB + WB + MB)} x (1 - RES)

  • TBP: Technique Base Power
  • CB: Class Bonus
  • WB: Weapon Bonus
  • MB: Merge Bonus
  • RES: Resistance

Special attacks on 9-star weapons

  • All non-rare weapons and most 9 Star weapons that attacks more than 3 times in a combo or attacks multiple enemies suffers a reduction. Reduction means the special is reduced to 1/2 or 1/3.
  • Most 10 Star and above rare weapons do not suffer a reduction. There are a few exceptions however.
  • If an item's hex value is underneath Photon Claw, the special will be reduced regardless of rarity.
