How difficult would it be to change Gird to cast another spell on the caster rather than Protect? Or similarly Pray to cast a spell other than Cure 1? Or for that matter Medicine or any other skill tied to a spell?
It should be easy.. JCE's hack changed Protect to Blink. As for Pray, it should work more or less like Gird, functionally speaking (it is another spell based command).
Medicine hasn't been looked through yet, but that's tied to the item AFAIK. It is not quite a spell in the traditional sense.. items are consider "magical" and are calculated as such.. but not truly "magic" in the same sense.
I was thinking it would be cool to have a skill called "Rage" that would berserk the user for 0 MP and give it to Cid instead of the silly "Scan" command. And as for Pray, it doesn't do enough to warrant the turn it so often wastes. I was thinking it could cast at least Cure 2, or maybe a multi-target Esuna or something.
Cid's Scan doesn't use the spell.. though there's a fair chance it just omits the animation step altogether...
