Monster Bio Pt. 1
|Assess 2 enemy types||Chapter 3||Auto-Cure Materia|
So long as you're completing the Side Quests when you first unlock them in Chapter 3, this Battle Intel will complete itself as it's the requirement for the Chadley's Report Quest. Essentially, Chadley will hand over the Assess Materia, this will allow you to scan enemies to discover their full stats and log it into Enemy Intel. For this particular Report, you'll only need to Assess two and you can easily find them in Scrapyard Boulevard or the other areas around the Sector 7 Slums.
Going forward, you'll want to keep Assess set to Cloud for the duration of the game and continue to Assess every new enemy you encounter, Chadley will have Reports later to Assess greater numbers.
