See I don't mean 'list of every single named spell under the sun' when I say that, what I mean is an overview of what he's capable of, from highs to lows. What's the use of having profiles if half or more of the information is hidden? None of my character's spells are hidden, so I don't see why Corban should be able to wing spells mildly related to any magic he has a mild memory of. (When he has short-term memory loss...)
In my opinion, if you give a single word as an example of a realm of magic, you should only be allowed the dictionary definition of that word, in terms of power.
"Evocation: Evocation is the act of calling upon or summoning a spirit, demon, god or other supernatural agent, in the Western mystery tradition." Nowhere does this say that non-sentient cryogenic kinetic controlling bombs are listed, and if they ought to be... that means evocation, for Corban, means he is able to summon anything that possibly exists out of... well... who knows where? That alone is millions of spells more than I've listed Myron having. Every single element or elemental combination in the table of elements! That... in my opinion, is kind of over-powered, or at least high powered, in that it allows Corban to do virtually whatever he wants with whatever he wants.
Secondly, it may be stated that Corban can control crystals, but this is described as carbokinesis, which revolves around the control of carbon, not the control of hydrogen. His control should still not surpass Myron's. Sure, he may have advanced understanding of the pattern in which ice takes when solidified, however he does not have an atomic control or understanding of water. This is where having something defined specifically in a profile should matter.
I can see Corban creating a bomb that temporarily disables kinetic energy within an area... however, to fully lock all motion in that area absolutely, and permanently, he would require such a strong & continuous supply of personal mana or energy, which he should need to focus on. And even then, to deny movement in its basic form, even to deny magical or spiritual control, must require he manifest his own control over it on an absolute and godlike level, dividing it from time itself almost. I just don't see the current version of it, concocted within a second, having such absolute sway. You seem to want Corban to be able to nullify every type of magic Myron has, instantly, whilst simultaneously having perfect spells that cannot be dismissed. Even though I have a way to block Corban's next attack in my head, and Myron's water icicles may not even matter in the end of things... I just don't see it as valid.
On another note, you didn't really give me proper explanations of his abilities. You also completely left out the category of divination from his spellset. I know what you wrote, however I'm asking you to add it to his visible profile because a judge may want to know exactly what Corban is capable of, before making a ruling. You said it's based on D&D, but not everyone plays D&D, I'm a Dungeon Master myself and I'm the one who has issues with a profile lacking necessary information.
Ignoring my requests about Ishtalle's unlisted spells constantly. When you say 'I have spells I don't have to tell you about before our battle,' that translates in my brain in to: "If you get an advantage on me, I'm going to metagame."
