Re: jack's aurora
Well, if you're asking how to change the special effects of it then:
Open up FE.
Click on game.bin in the top left.
(I am hoping that those first two steps should be fairly obvious)
Scroll down to "SPECIAL_ABILITIES_PHYSICAL_SHIELD_DEF" and click on the plus sign next to it.
Then click on "SPECIAL_ABILITIES_PHYSICAL_SHIELD_DEF_INSTANCE".
Now click on the only title that comes up in the new box.
You should be here:
Next click on the "
Links to (GameBINEntryID) :"
Then once again click the only title that appears.
Now one or more of these is the one you want to change. I have no idea which one it is since I haven't played around with it at all. But whichever one you do decide to test out, replace the number with 292 also known as "JACK_OF_BLADES_POWER_1" which is basically the aura you're looking for.
And remember, before you test out any of these,
make back-ups.
