Emerald WEAPON

Hp/Mp: 999.999/9999
Emerald is the toughest creature in the game. Its attacks can do around 6000 damage and he has one attack that can kill your party instantaneously (Air Tame Storm). Before you engage him, make sure youhave these materias installed:

- Knights of the Round (Minimal: level 3)

- Phoenix linked to Final Attack (level 3)

- Mime (2x)

- Big Guard or Time materia

- Mp Turbo linked to the Knights.

- Underwater materia

First of all, cast Haste or Big Guard on all allies. Emerald will try to kill you first so don't start the chain until he finished attacking you. Once its your turn, attack with Knights of the Round and let the others mime it. Thanks to the Mp Turbo, the Knights will do around 130.000 damage each time (Not the ones that are mimed). Emerald will retaliate from time to time with its Air Tame Storm, but Final Attack with Phoenix will revive you. Don't be afraid to use Megalixers and use Limit breaks only at the end of chains. You'll beat him eventually. Emerald will leave the Earth Harp which you can exchange for 3 Master materias. Go to the old man in Kalm and talk to him.

Ruby WEAPON

One of the most powerful creatures in the game and hard to beat. To beat him make sure you have these materias first:

- Knights of the Round (Minimal: level 2)

- Hades (Minimal: level 3)

- Big Guard Enemy skill

- Mime (2x)

- Phoenix

To make sure Ruby won't suck your characters away, kill with Cloud the other party members first (In a random encounter). Then bump with the Highwind into Ruby. He'll jump out of the sand and attacks you. Unlike normal, it will stick its claws directly into the sand. Now, before you do anything, cast Hades on him. This will stop him. Now cast Phoenix followed by Big Guard. All 3 characters should be revived to the fullest and have a barrier with haste (Thanks to Big Guard). Now start the Knights of the Round chain. Cast with Cloud the Knights and let the other two Mime it. Then cast Hades again on Ruby to make sure it will be stopped again. Continue this routine and deal enough damage to eventually kill it. Ruby will leave the Desert Rose. Give this to the old man in Kalm to get a Golden Chocobo.

Ultimate WEAPON

Hp/Mp: ????/???


Like Diamond, this one is fairly easy (except the last battle). Haste yourself and use Regen too. Use your best summon spells and magic. When it flies away, follow it with the Highwind and keep bugging it until it stops at one location (Most used: Corel, Fort Condor, Cosmo Canyon). Once it finally hovers near Cosmo Canyon, the final battle starts. Simply react the same but keep your Hp up! Since it can do a special attack called Shadow Flare which does 6.000+ damage.

Diamond WEAPON

Hp/Mp: ????/???


This WEAPON is fairly easy, simply Haste yourself and use Regen if necessary. Use everything you have against it: Ultima, Summon spells, Comet2 etc. You won't be able to kill it though, when you deal enough damage, it senses that Shinra is trying to remove the barrier at the Northern Cave. It later gets killed by a megablast of the Sister Ray.
