The Last Cactuar

The gatekeepers will let you into the Cactuar Hollow. A short ways down the passage, you'll run into a forced battle with a Sallet and a Cactuar. After the battle, you'll have to defeat a Heavy Sallet. Follow the passageway, picking up a Ether near a sandfall.

When you reach the room filled with sand, hurry through. If you're quick, you can get these item in chests on top of the pillars: Faerie Earrings, Mega Phoenix, Hi-Potion, Megalixir, Twist Headband, Ether, Mute Shock, Beaded Brooch, and Phoenix Down. Don't worry if you don't make it, you'll just be brought back to the first sandfall.

Continue down the passage until you run into Frailea. If you manage to beat Frailea in the shootout mini-game, you'll receive the Covenant of Growth grid. Afterward, you must defeat Jumbo Cactuar and Cactuar x2. Mission Complete!
