But what do you guys think? And do you think we should keep track of individual spells or just say the characters have proficiency with different types of magic and Character Level just denotes how good they are at it? From a narrative standpoint, there could still be arcane runes and scripts for spells and incantations, but when writing the battle scenes out, we could just describe the magical effect being created rather than keeping track of individual spell names and such.

I don't know about everyone else, but for my own part, I was planning to keep track of individual spells. Not going as far as incantations for them, granted, but certainly keeping track of each individual spell Malcer is capable of and making specific mention ICly when he is researching a new spell before it gets used in a later battle or other scenario. And when it comes to proficiency, I'm planning to move Malcer's capacity in the various "Circles" of magic (1-9 and such) according to 5e access to those tiers. So, at level 3, he'll start breaking out the second tier magic, and at 5th level, 3rd tier and so on. When it actually comes to using the spells in practice, however, I'll probably only describe the effect occurring.
