No Parameters - Returns Nothing

If Target Current Action is Nullified (TCA Evade type = 0x05) : skip everything
Check For TCA special flag 2 0x04 (Absorption)
  - If Absorption is ON : - Set TCA attack Type = HP recovery (0x40)
                          - Nullify TCA HP Damage
                          - Set HP recovery amount to previous HP damage
  - If Abosorption is OFF : Set TCA Attack Type = HP damage (0x80)

Rq : Evade Type 0x05 and Absorption flag are set in Elemental_Damage_Modification
