Emerald Weapon

Location

The Emerald Weapon roams the ocean floor. It appears once you've gotten a Grey or Red Shinra Submarine in Disc 2, after completing the Junon Huge Materia Quest.

I recommend you leave Emerald and Ruby until the last possible minute in Disc 3, because your party members will have greater powers.
I also recommend that you defeat Ruby first.

Who To Use?

You get 50,000 AP for defeating Emerald, so you need to take this opportunity to take your Materia up to Master level. For this I recommend :-

• Cloud equipped with his Apocalypse Sword (Triple Materia Growth)
• Cid equipped with his Scimitar Spear (Triple Materia Growth)
• Anybody else equipped with a Double Growth Weapon.

Other Equipment

• Equip all 3 Characters with a Ribbon if possible.
• Give all 3 Characters some Armour with 8 Linked Materia Slots, a Wizard Bracelet.

Essential Materia

In order to defeat Emerald you must have the following Materia :-

• Underwater Materia
  To get the Underwater Materia you have to Morph the Skeleton Ship found in the Underwater Tunnel under Junon, then take the Guide Book to the old man in Kalm, who will give you the Underwater Materia.

  Final Attack linked to Phoenix Summon Materia

  It is essential that both of these are taken up to Master Level beforehand.

  W-Summon

  Knights of Round Summon

  This needs to be taken up to at least 4 stars.

  3x Mime Materia

  Each character needs to have a Mime Materia, but I have done it with two.

  W-Item

  You don't need to have this equipped during the battle, but you need to use it beforehand to replicate at least 25 Megaelixiers (using the W-Item trick).

  Big Guard Enemy Skill

  Restore Materia

  You really need this taken to the third level, Regen.

  HP and MP Plus Materia

  To stand any chance of defeating Emerald, you characters need 9999 HP and as much MP as possible.

Other Materia

Choose the placement of your Materia carefully. Make sure you place Materia that has less AP than others in the Triple or Double growth weapons.
After you have equiped the essential Materia, fill up the rest of the slots with any other Materia that needs to be taken up to Master Level. As you receive Magic, Command, and Summon Master Materia for defeating Emerald, I recommend equiping as many Command Materia Orbs as possible.

If my tactic is to work you must not equip any type of Counter Attack.

Battle Strategy

If you don't use the Underwater Materia, you only have 20 minutes to kill Emerald in.
Remember, this is only my prefered way of doing things, there are many other ways to do this.

• Cast "Big Guard" Enemy Skill.
• Cast Regen.
• Use a Megaelixier.
• Cast Knights of Round twice (using W-Summon).
• Use the Mime Command at each characters turn (this will mean each character casts Knights of Round twice without using up and MP).

  Keep on repeating the Mime Command (it takes about 30 Minutes to kill Emerald).

If Emerald kills your characters, the person who has Final Attack linked to Phoenix will bring all your characters back to life.
If this happens, just repeat the above instructions again.
