Add "Poach" to Foe, HP = critical" as a gambit to someone in your party, it will get you the prime loot

I'm still leveling up early in the game but I found out that the Lhusu mines skeletons drop 200 gil bone fragments, the tomatos at Ogir Yensa drop 300 gil succulent fruit and those "armored Ulstrix" at Nam Yensa drop 1000 gil crooked staffs. Great places to line up your party's pockets
