[X] Magic Knight - While a bit limited in your spells your Arsenal is usually fire balls, thunderstrikes, magic shieldbubbles and more. An unlike other Magic users your not as squishy thanks to your powerful magical armor, shield, and weapons.
Seems legit, though it might be better to hammer out the exact limits of our power later. The thing with magic (in most cases) is you can start off with a few simple spells and learn more or refine what we have as we adventure.
To suggest a few "class features"
1. A patron. Kind of like a 5e warlock who chooses a fey patron (or a varient where they can choose a celestial being) we could have gotten our magical knowledge and such from a being connected to Arthurian legends or the knighthood. Like the
Lady of the Lake, or somesuch. Or we got a book on knightly magic. Basically some source of our magic we can use to gradually learn more from.
2. Create or conjure armor. We obviously got our armor from somewhere and it kinda makes sense that we used our magic to make it, even if that involved rolling up our sleeves, making a forge, and smithing one ourselves (maybe using some spells to boost our crafting skill and strength, Skyim style).
3. Strength, agility, and durability boosts. Along with maybe some healing. The path of a magic knight is less flashy fireballs and more just boosting your existing strength and ability. Granted, this is basically the magic oriented path towards getting super strength... but what's wrong with that?
4. Crafting. Maybe along with our durable armor we enchant to be stronger, bulletproof, etc. And our weapons with long-lasting enchantments of their own, the majority of our other flashier attacks or abilities are tied to magic items? If we want to throw a fireball, we need to craft a staff of fire. If we want to walk on water, we enchant our boots. Think more like the Legend of Zelda than D&D. Our actual list of magical options in a situation would be more limited by what we can carry into battle than simply memorizing spells.
Granted, that could make us seem like a magical Batman in shining armor, running around using magical keys to bypass locks, or enchanted rope to rapidly climb up buildings, etc.
I suppose even that would require a sort of limit, like a person has to be trained in magic or be accepted into the knighthood to be able to use these items. So we can't just stay at home crafting stuff for the police.
Our magic items are less self-contained devices and more like necessary focuses for channeling our magic.
