I DON'T KNOW HOW TO KILL DARK CECIL AFTER BEATING SCARMALONG AND ENTERING THE SHRINE!!I
HAVE A LOT OF SUPPLIES BUT I DON'T KNOW WHAT TO DO!(what does the voice mean by a paladin
has no malice and what-ever(forgot what he said XD) your blade and overcome your hate?does
he mean kill it?)

Anyways, the matter of what the voice said "overcome your hate" means to defend. As pure
Light, you will only use Defensive tactics instead of attacking. Only pure Darkness
attacks.

So what you do is at the beginning of the Dark Knight Cecil battle, you will only Defend
until the battle ends.

how do i kill that moving wall in the under wold

You must have Rosa at least learn Slow.

Then have Kain to use Jump, Cecil Attack (if you have Darkness and or Focus, use Focus 3
times and then Darkness, finally execute your strong Attack), Edge just Attack, Rydia uses
Leviathan (if you haven't got this, then use Dragon), Rosa just heals the party if
available.

It's also important to have Rosa to cast Haste to the entire party so you can execute your
commands faster. If you haven't got Slow or Haste for Rosa, you are definitely screwed.
But, if you have Spider Silk (Slow), use it right away. If you also have Hermes Slippers,
use it for Kain, Cecil and Edge if there's enough.

You should, by now, have Rosa use the ability Fast Talk and Doublecast. If not, do it in a
hard way.

Time is your weapon.
