Misc. Combos- a mastered Magic Counter and a Fullcure
or Restore materia. These are a few more tips from people who have
emailed me.
1. KoR->MP Turbo(LV 2+),Magic Plus(30%+), throw in a MP Absorb->KoR
or
Master Summon to gain MP as well. You will do 9999 damage 13 TIMES!!!,
gain
MP as well.
2. Double Cut(4x-Cut)->Added Cut, the more,the merrier.
3. Mime->[limit break] mime your own limit break!
4. Final Attack->Phoenix,Phoenix->MP Absorb,Final Attack->KoR
Mime- A good combo w/ this could be Counter linked to Mime. When you're attacked, you do the last action the party did.
HP and MP Absorb- Linked together-Try linking these baddies to the same materia. Say you've got a Knights of the Round and a Master Summon. Link one absorb to the KotR and the other to the Master Summon. Then go into a battle, cast KotR, and you'll get both HP and MP back! Pretty sweet, huh? This will work on any materia, just make sure you have 2 of it or you have a master materia of it's type. Also make sure that if it is a magic spell, that if you use 2 of the same materia that they can cast the same spell. You could have an absorb linked to a mastered Lightning materia and the other linked to a brand new Lightning. Then the only spell that will bring back both HP and MP will be Bolt. Bolt2 and Bolt3 won't work because not both materia can cast those 2 spells.
Counter Attack- The more of these that you have, the more times you'll counter attack. Say you have 3 of them equipped on one person. If that person is attacked, they will attack 3 times in return! A good combo to use would be to have the 3 Counter Attacks, get a Counter materia, link it to a magic materia, and then link other versions of that materia(master magic or a copy of it, just make sure they're all at the same level) to HP and MP Absorb. What you're getting in return is 3 physical attacks, a magic attack, and HP and MP! The best part is, you haven't even had your turn yet! This is one of my fave combos.
Deathblow- There are a lot of nice Deathblow combos. If you want the most out of them, master the Deathblow materia so that when you use it, the hit percentage is 100%. Then link it to some materia listed below. Steal as Well-Critical hit and steal at the same time. Absorb materia-Critical hit and HP or MP in return. Try linking each absorb to a Deathblow. You could also try linking Deathblow + Added Cut.
Elementals- These are some good combos. If you link an Elemental materia to a Lightning materia and put the combo in your weapon, your weapon will become a lightning-based weapon. It also does more damage on enemies whose weakness is lightning. This combo also works w/ Fire and Ice. If you link an Elemental materia to a Lightning materia and put the combo in your armor, you will nullify all lightning attacks which means that no lightning attack can harm you. This can also be used w/ Fire and Ice.
Quad Magic- This materia can be used in MANY different ways. The best way though is to use it w/ a magic materia. Say you use it w/ Ultima. If both materia are mastered, Quad will cast Ultima 4 times for the price of 1. But, if you use W-Magic, it will cast it 8 times for the price of 2. If you have Mime materias, have the next characters mime it. You'll actually be casting Ultima 24 times for the price of casting it 2 times! Pretty cool, huh? You could also link further versions of the materia w/ MP Absorb and sometimes you'll get back more MP than it cost to cast the magic twice! Quad Magic can be used w/ any magic materia and every summon except for KotR. Quadra Magic + Fire is a really good combo.
Final Attack- Possibly one of the best materia in the game. There are only 2 combos that should be used w/ this materia. Those combos are Final Attack linked to Phoenix or Final Attack linked to master Revive and another master Revive linked to All. The Phoenix combo casts Life2 on all members and does some Phoenix Fire magic on the enemy. The Revive combo cast Life2 on everyone. Personally, I think the Phoenix combo is better because it saves you 2 materia slots and also it does some damage to the enemy. This last materia pair is from Steve. I haven't tried it yet but it sounds like a kick ass combo. Here it is: If you pair master summon and quadra magic, Pheonix linked and final attack, bahamut zero and magic counter
If you have a good combo that isn't listed up here, e-mail with the combo. You will be given credit if it is put up here.
