'''BATTLE.BIN''' :  - AI_ability_processing
 +
Handles Ability simulation (including potential reflect) - Set some AI flags (hostility check, Effect on acting unit) - Change priority (mostly for Ability that affect stats)
 +
------------------------------------------------------------------------------------------
 +
Parameter : r4 : Pointer to Action Data (Battle 0x16e format) - Acting Unit or Targeted Unit with reflect
 +
            r5 = 0x00 if Acting Unit Action / 0x01 if Target with Reflect (recursive call)
 +
Return : Nothing

BATTLE.BIN :  - AI_ability_processing
Handles Ability simulation (including potential reflect) - Set some AI flags (hostility check, Effect on acting unit) - Change priority (mostly for Ability that affect stats)
------------------------------------------------------------------------------------------
Parameter : r4 : Pointer to Action Data (Battle 0x16e format) - Acting Unit or Targeted Unit with reflect
            r5 = 0x00 if Acting Unit Action / 0x01 if Target with Reflect (recursive call)
Return : Nothing
