Defeat Emerald Weapon in Final Fantasy 7

Emerald Weapon is likely the most difficult boss in Final Fantasy VII. However, he is also an optional 'superboss', so only the most skilled or completionist players should take him on.

Steps

  1. Max out your characters. Furthermore, it's always good to obtain the best weapons and armor. Some materia you will need include: Mime, Final Attack, the Phoenix summon, and x2 Attack. Ensure everyone has their final limit breaks too, especially Cloud's Omnislash, probably the most powerful of them all.
  2. Max out all the materia listed above. This phase takes a lot of time and patience. It's best to get the Apocalypse Sword for Cloud in that jungle area with the frogs as it boasts triple exp for any materia equipped in it. You need to max out all the materia listed above not only to have them at full power, but so they duplicate and can be used by other characters. Just grind until all the material you choose is maxed, duplicated, and maxed again. The more the better.
  3. Prepare for the actual fight. Ensure every character's Limit gauge is full before encountering Emerald. Make sure Cloud and another party member has the Mime materia equipped as well as someone else in your party. Also, equip the Final Attack materia in a linked slot with the Phoenix summon; with this combination, the death of that character will trigger Phoenix, resurrecting your entire party. This is key for when Emerald weapon does his random evil 'kill everyone' attack.
  4. Start the fight by casting Wall and Regen on everyone. Don't use any limit breaks until this is done--when finished, use Cloud's Omnislash limit. Don't allow the other party members to use their own limits; instead, pass their turns until Cloud's comes up, and have him use the Mime ability. Repeat this as many times as possible before you die. Omni slash hits 15 times, if your maxed out doing 9999 every hit, that almost 15000 damage.
  5. The key to doing massive damage is limit breaks and mime. Some favour the summon Knights of the Round, but if you don't have a Gold Chocobo and the materia for breathing underwater, the fight has a strict 20-minute timer. Extreme damage in a short time is essential, and the long animation of Knights of the Round works against your time limit.
  6. Mime also duplicates items at no cost. That is, you can use a mega-elixir to fully heal your party then mime the item to use it again.
  7. Ensure the party member with Final Attack > Phoenix equipped has sufficient MP. If he/she has none upon their death, they cannot resurrect the party and your efforts will have been wasted. Remember Emerald Weapon's MP draining attacks and use appropriate items.
  8. If Cloud dies but other party members remain, use their limits and Mime them in the same manner. Emerald will KO your characters many times over the course of the battle, and your turns will be better spent attacking/buffing than resurrecting. Wait for the Final Attack > Phoenix combo to take effect.
  9. Understand that winning is not always a guarantee. Emerald Weapon is an unrelenting and powerful boss and won't always let you use one last item. You might have to take him on a number of times before seeing some degree of success. A little luck goes a long way.
  10. Don't bother with conventional attacks.If you do not have a Limit attack charged and ready, try to heal the HP/MP of party members rather than perform an essentially ineffective attack. Burst damage is the key. Emerald Weapon's attacks are strong, so your Limit Gauges will fill up quickly. It's better to be at full strength when your limits are ready rather than being forced to spend one more turn healing your party.



Tips

  • For extra difficulty and reward, attempt the fight with Cloud's Apocalypse Sword equipped. He'll cause less damage but whatever materia are equipped will be instantly maxed out.
  • If you win, go to the traveler in Kalm(the man upstairs in the house the furthest to the right) and turn in the item won for every master materia.
  • The same general strategy works for the fight with Ruby Weapon, with one exception: enter the fight with one character already KOed. This prevents Ruby from fighting at his full strength.

Warnings

  • Keep trying; this fight is about half luck and half gear/skill.
  • Many hours are needed to do this. Plan on having your game timer at 99.99 for a while.
  • Try to predict Emerald's attack patterns during the fight. This will tell you when is best to be on the offensive and when it is better to heal/buff. This ability will come to you with experience.
