The junctioning system was almost exactly the same thing it was with the materias in FF7. I guess this is not of much help for Jolie, tho
IS simple: as you already know, teh first thing you attach to your characters are the Guradian Forces. I really don't know if from the beginning the characters have a certain affinity to certain GF's or it's just somethign you build up. the only thing I'd recommend, is to keep the same GF's in the same chars, and avoid changing them as much as you can, so their affinities keep unaffected (example: let's say you have Ifrit attached to Squall for a while, and then you decide to detach Ifrit and attach Shiva. by using Shiva, Squall's affinity with Ifrit will decrease, and by default, Squall's affinity to ice will be weaker. You must have in mind the rules about elements, that I am sure you already know since long ago.)
Well, as for the "draw" command, is just teh same thing as if you were stealing. You just get magic from the enemies by doing this, the more you get, the better for you. What you shall know and have very clear, is the kind of magics you get. Some of them are elementals, and the others are just support or status magics. elementals are obvious: fire, ice, water, earth, thunder, wind, gravity/darkness, holy, flare, and ultima. (if I'm not wrong that's all of them)
Junctioning elemental mategics is basically the same thing as with GF's if you have fire juncioned to your weapon, you'll be stronger against ice or water elemental enemies, but weaker or just hand to hand against fire-based foes. And just remember that the more you have, the more powerful you are.
As you can also se, you have slots for attack and for defense. If you are fighing a thunder based boss, teh wisest thing is to do is to stcok up on thunder magic and pu it on the defense, so you can either be resistant to it's attacks, or immune to them, or in the best case, absorb them.
As for the status magics (poison, death, zombie, sleep, etc...) you use it the same way as with elementals, but with different purposes: to raise your chance either to cause status disorders to your enemies with your physical attacks, or to be able to defend yourself against such.
I guess that's the essential stuff that you need to know about junctioning. I hope that helps
(although I know I can sound confusing a times
)
