Latest revision as of 12:24, 14 April 2022

No Parameters - Returns nothing

If Ability flag [Evadeable] is Off : skip the whole routine
This routine Will set the value of the displayed Hit% 
  - Forced to 0x00 if Any Current Ability Evade data is greater than base hit value
  - If Attack might succeed : Hit% is calculated in the central math section
Last part of the routine Roll Each Evade type against Current Ability Base Hit (That's why halving base Hit = doubling all evasion type (cf Defend mechanics))
Update Target current action 0x2a (Hit%) and if Evaded then update Target current action 0x00 (Hit flag) 0x02 (Evade Type) and 0x03 (Used Item for evasion)
