I need some extreme help on FFIV Advance. I'm stuck on the part where Cecil becomes a paladin and has to battle his dark knight self. Any tips?

If you're stuck on the battle part, all you have to do is defend (block, or whatever the option is), and stay alive. Just defend, do not attack him.

Then what happens?

Just keep blocking, and eventually the battle ends. I don't want to spoil anything for you, so I won't say anything more. ^^;;

EDIT: How do you beat Beigan? I've died 3 times now.

Mmm... sorry, that name isn't ringing any bells right now... Could you fill me in? I'm guessing he's right after Cecil becomes a paladin, right?

Yeah. When you sneak into Castle Baron and he attacks you.

Oh god, he's the big ogre guy right? Attack his arms first then beat on him until they regenerate. (I think that's how the fight goes, you can kill his arms but they come back) He is really tough, and it took me a while to beat him. If you still have trouble, level up a bit. The game is even harder on the PS version, I don't think there was ever a time that I wasn't 10-20 levels underlevel (according to the guide suggested levels anyways).

Okay, I'll do that. I at least know what he's weak against.
