Ok. I can't find the third cactuar gatekeeper. He's supposed to be in a treasure chest in a sphere hunter's house. I checked everywhere in Kilika port and guadosalam.

Also, how the heck can I beat that sanctuary keeper clone in "the heart of the farplane." I got Yuna Lv. 81 (Mastered Samurai and Gunner) Rikku Lv. 69 (Mastered thief and gun mage) and Paine Lv. 82 (Mastered Warrior and Lady Luck). Strategies would be really helpful but no spoilers please.
