No Parameters - Returns Nothing         Alternatives notes : Use_Specific_Action_Hit_Percentage

Uses Target Current Action (TCA) HP damage as Ability Hit score (and clear HP damage in the process)
 - If TCA HP damage > 100 : skip the routine (Attack Hits)
 - Else 
    - If Action state is not being executed (<> 0x00) : Modifiy TCA 0x2a (Hit%) to Hit score * Evasion% (Display Hit%)
    - If Action is being executed : roll a random (0 to 100) against Hit score. If Attack miss, clear hit flag and set TCA evade type to 0x06
Note : Evasion is ignored when rolling hit score vs random because Evasion roll is already done (sooner in formula)
