Welcome to Gaia! ::

okay partial credit is awarded 3 1/2 out of 4

well i was the one giving the quiz but i can answer, to beat ruby weapon KO two of your party members so that ruby can not get rid of them with the sand pit, he will then put his hands into the ground where they will attack you from behind, just put on a ribbon and attack the main body while one person focuses on healing, *hint hint* get the W-item materia in the subways when you parachute into midgar, you can use that to get infinite elixrs and mega-elixrs* othere then that there are many more ways to beat him

two things you must do before fighting emerald weapon, get the underwater materia from the traveler man in Kalm by giving him a guide book from the ghost ship in the underwater mako reactor *need to morph the ghost ship* and then you need either mime or Knights of the Round

*note i am not really that big of a fan, i just played the game that much cause i was only 6 or 7 at the time and just kept restarting
