The Manipulation Technique
|Defeat 2 or more enemies with a single attack||Chapter 8||Provoke Materia|
You'll be able to receive this Battle Intel once you reach Chadley in Chapter 8 and like many of the other Reports, this is an easy one that should almost certainly complete itself automatically. You'll need to kill at least 2 enemies with a single attack, something that you've probably already achieved by holding down the [SQUARE] button with Cloud for his sweeping attack. If for some reason you've yet to do this, make use of Triple Slash against enemies close together.
