Cassily: "Mm, 'spose. Guess it's not a problem if you're not carrying them on you at all times."

You wait for Leon to finish looking at the ammo, then the two of you head out to find a spell shop. There's not many shops for selling spells, since most demand can be met by a single merchant with a few proctors.
Leon: "What kind of spells you thinking of getting right now? Something to attach to your bullets I assume."

Leon: "My ice spell can do that. Dumps all its energy into making cold when it hits, instead of using it for endurance or ice production. I could teach it to you, if you want."

Leon: "Heh, not a problem for me. Is there anything you do want aside from basic elemental bolt spells?"

Leon: "Uhhh, a lot. Depends on what you're looking for mostly.
Attack spells there's a variety of stuff for all 8 elements. Bolts, explosive projectiles, waves, walls, shields and barriers, all kinds of things at all kinds of levels of strength.
I've heard Madosa has a good selection, but the Wizard Academy would probably be your best bet for any and every spell you can think of. And if they don't have it, they could make it. Buuut, they aren't exactly a shop and they wouldn't be happy with me after I ran off.
Support magic, buffs for strength or speed with wind usually. Debuffs for the same sort. Healing, but I think you already know about that. More complicated and niche stuff, all over.
Oh, meta spells, do you know any of those? You probably wouldn't if you've just learned healing magic."

Meta spells, that was touched upon in your classes. It was more a subject for combat magic classes, which you didn't take, but the gist is addon spells that attach to regular spells and augment their functionality, usually by delaying or changing their casting somehow. The most common one is storing a spell for later use, letting you just cast it at any time afterwards. There are various limits and restrictions which you're not familiar with, but meta spells do become an important part of any advanced mage's arsenal.
You do know that healing spells, due to their complexity, don't play well with meta spells. Another of those "Beware of tumors" warnings.

Leon: "Yeah, pretty much. I know the stored spell meta, I can teach you that too I suppose.
Huh. That might work well with the bullets actually. It has to be manually triggered so that's useless after you shoot, but it does help stabilize spells for long term, so you could use that to make bullets ahead of time. Would still need to arm them before you shot."

Leon: "Normally yeah, that's how it'd work. But with the bullets, all the mana for the spell can come from the bullet. You wouldn't have to store any additional mana, unless you had a spell that needed or supported additional power."

Leon: "Sure. Anything we don't get to I can teach you on the ship. Might as well do the more dangerous one here."
The two of you head over to the training grounds again and check the same field out as you were using before.
Leon: "Alright, ice bolt."
