Arcane and Rune Magic at the Same Time
To use them both you need the gift for Rune Magic and a Rune Sword. Go buy Arcane Magic, discarding the Rune magic. In battle use the Victory Rune with the Rune Sword and you will learn Rune Magic. You can now equip both Rune and Arcane Magic.
Asura blade for other people
The Asura is one of the most deadliest blades in the game if you use it correctly. You can receive the Asura (without Asselus) by "earning the right to find the Time Lord". When the lady lets you go to Chateau Aguille to pick up the Sand Vessel, pick up the Asura. It is possible to get it at this time. When you have it, give the Asura to one of your master swordsmen. If you choose to attack with Asura during battle and are hit, it will randomly use the Asura Counter-attack, which in many of the cases will kill an opponent with one hit.
Five Character Combo
Here is a combo that I stumbled upon that uses all five people. It has done around five thousand points of damage to many bosses. To do it have one each character do one of the following acts. Air Throw, Thrust, Implosion, Wheel Slash and Thunder Thrust. It works best if all five characters are roughly the same speed.
Equip T260/T260G with 3 Hyper Blasters and 4 War-lord Armors in its Type 1 body. It will have 999 HP and 99 defense.
Permanent Overdrive with Blue
First Blue must have the following spells:
Overdrive: Time Magic
Stasis Rune: Rune Magic
Shadow Servant: Shadow Magic
-Go into overdrive.
-Overdrive gives you about five to nine turns depending how experienced you are.
-Cast Shadow Servant.
-Do any spells you want while in overdrive.
-On your last turn in overdrive cast stasis rune.
This will prevent you from losing you JP!
Overdrive will take 10JP each time.
Repeat until you have no JP or the enemy is dead.
If you come out of overdrive without stasis you will lose your JP.
But you will have five to nine turns permanently after stasis rune wears out.
Play as Rouge
At the begining of the game select Lute. After you arive at Manhatan go to Luminous and first get the magician Rouge, to join you. Now you can play as Rouge, but if you travel to Magic Kingdom you will lose him.
Tips on Linking Combos
There are 4 main ways to make combos::
1) Do a charging attack then a standing attack. You can do a charging attack (like NoMoment) then a standing still attack (like Doubleslash) and they should connect well.
2) Cast 2 spells of conflicting schools. Spells of opposite elements seem to connect extremely well (shadow and light, time and space, etc.)
3) Use the same spell/attack twice in a row. You can actually do a combo of 5 swallow swings.
4) Add onto already existing combos. Here are a couple of things you should know. Fist is THE best combo linker, Life Sprinkler is a good finishing move, and Turbid Current is an excellent move to start combos with.
