Emerald Weapon Stats: HP: 1000000, MP: 100, XP: 50000, AP: 50000, GIL: 50000

The Emerald Weapon is located under the ocean, accessible by the Submarine and can be approached by making contact. You'll have 20 minutes to complete the battle unless you have the Underwater Materia.

How to win: Start by casting W-Summon using Bahamut ZERO and Knights of the Round with your second character. Have Cloud mimic your second character. This combo will allow Bahamut ZERO to be cast 4 times and Knights of the Round once afterward. Keep mimicking with Cloud, skipping other characters' turns. After several Bahamut ZERO and Knights of the Round attacks, Emerald Weapon will probably try to kill you with Aire Tam Storm. Phoenix will revive your group and you'll have to start the combination over again. After you've defeated the Emerald Weapon, you'll aquire the Earth Harp. You can exchange with the man at Kalm for three Master Materias.
