NOTE: They gain 1 brave point every turn, so keep it under 10 or they'll turn back.
First, move within four spaces of Velius and use wave fist. Then you should get another turn. Use wave fist again and then jump across the water on the right.
I think Velius gets his turn next and he'll use Cyclops. While he's charging, move your guys away from the target. If he targeted a certain person, attack him directly with that person. Hopefully, you'll have a summoner left. Cast Lich (It'll hit him for around 500, and he has 1000hp)
By now he should be almost dead. Just use anything you can to finish him off
Start out by getting as close to him as you can. Then use wave fist. He will then use Lightning Stab and run away. DON'T FOLLOW HIM. Run back to where you started and use chakra. He will then move to where he started. Now repeat all this until he's dead.
Here's my take on how to beat Balk and his crew of beasts.
First, use the sword duping trick to make a number of "Excalibur" and "Save the Queen".
Change Ramza's job to Knight if you don't have him there already, and equip both the swords stated above (must have the Two Swords ability from the Ninja job class [900 JP]). This will automatically put him in [Haste] and [Protect].
Have whatever ability you want for your secondary action ability. Use Blade Grasp for your Reaction ability, Two Swords for Support ability, and Move-HP UP for Movement.
NOTE: This combination of abilities and items works well with ANY character, but you may not have spent enough time with everyone, having Ramza the only one capable.
For the rest of my team, I included Mustadio as an Engineer (with Mythril Gun), Orlandu as Holy Swordsman (with Excalibur and Save the Queen if possible), Agrias as Holy Knight, and a Ninja.
Equip the best armor you have (Reflect Armor works OK here). The Defense Armlet is the best accessory to have (so Balk can't use his Snipe skills on you), but Rubber Shoes (accessory) are useful when Balk tries to shoot you with his Lightning-aligned Blast Gun. Use whichever is handy, but equip the Defense Armlet(s) on your best character(s).
Use Mustadio's "Snipe" ability on the monsters to paralyze them. Pick each one off in turn with Ramza and the Ninja going up close with Two Swords, while Agrias and Orlandu get them with Lightning Stab (or the best skill you have).
Note: You can just attack the Behemoth until its health is "Critical". It'll leave you alone. The three other monsters can hit you with their firey breath (and from fairly far away), so make sure you kill them off completely.
You can't paralyze Balk, so you have to concentrate on surrounding him. He runs away easily and can hit you with his Blast Gun, so go after him quickly (once you've eliminated the monsters). Try to break his Blast Gun first with Orlandu's Hellcry Punch. After that, he's easy to defeat with ANY ally. Good luck!
For example, to duplicate Excaliber, go to Lionel castle's shop. You'll get a second Excalibur for only 10 gold!
Walk across any green dot until you are attacked, then kill all but one enemy. Next, find five squares that form an + and are on the same height level. Have the monk stand in the center with all other characters in the adjacent squares. Use accumalte over and over and when your attacked just use chakra to gain back your health. Repeat as desired.
What you do is you turn your enemies into frogs. It is time consuming, but it is worth it. (You can increase chances by using oracle "pray faith." Once that is done. and I know this sounds weird, turn your strong character into a frog. Then with oracle or mediator, put him into berserk. This will allow him to fight on auto-battle without running away. Keep your character well healed. Then move the rest of your characters far away from the fight. Frogs VS Frogs. Put them on auto battle in "Run like a rabbit" mode so they don't interfere. They shouldn't interfere.
Leave it on over night. By morning that character will rise 5-10 levels, and have over 2000-5000 jp points.
When Cloud joins your party all he can do is defend and attack. You'll need to find his Materia Blade so that he can use all of his limit attacks from Final Fantasy VII.
The Materia Blade is located in the Bervania Volcano. Set your party's on Move-Find Item Then go to the highest tall rock and go to the top of it.
Warning: When you kill undead this way a timer will appear. If you don't finish the game before the timer reaches 0 the undead will rise again.
Note: This tip only works in the Japanese version.
You can get your Brave up to 97. This works great if you have the Blade Grasp skill because the enemies will only have a three percent chance of hitting you!
Make sure Ramza is a Squire with two sword ability or a Ninja with HP Restore and the support skill Guts equipped.
When you start the battle it's just you (Ramza) and Weigraff. Don't attack him, instead keep away from him and use Yell and Accumilate repeatedly when it's your turn.
Eventualy this will raise your speed and level high enough that you don't have to worry about his Lightning Stab or Earth Slash attack.
When you are getting 3 to 4 consecutive turns in a row (Check the AT list) wait until the beginning of the next cycle then attack. Your two-sword ability should kill Weigraff in one turn and Velius will be dispatched before anyone else even gets a turn.
This should make what was the hardest battle in the game quite simple. Good luck!
