Alright now that I actually did more than skim the sheets, a couple nitpicks.

[@Lewascan2] For starters, inducing early noesis is a quick way to make manaburn barbeque out of your kid, assuming one understood the process enough to even try, and soul alteration in general rarely leads to anything positive for the one being altered. Seems like a massive risk to take for a mere ~3-4 years of extra magical training that's probably wasted on a 7 year old that won't understand any of it anyway.

The magic section is also well beyond what an 18 year old mage would be capable of; even expert necromancers have a hard time finely commanding scores of undead beyond giving vague directions to the entire shambling horde at once. Same with unraveling other mages' spells and reshaping biology, which are other schools of magic entirely and usually have a High Magic component. As for the whole ghost part, trying to pull a spirit or some semblance of a lingering essence from a dead body only works if it has freshly died, otherwise the soul would have vacated its earthly fetters by then and be unretrievable. Spirits rarely linger unless acted upon by magic designed to do so. Likewise, the rest of her skillset is way too broad and developed for a teenager, let alone one that was a child soldier. Only so many hours in a day and whatnot.

As for the items, the whole crypt is pretty much out the window in terms of enchantment complexity. It'd take a team of archmages to run something like that long-term and it definitely wouldn't be portable. The staff's fine, but the part about self-maintenance doesn't work. Luckily staves are pretty hardy and only substantially degrade after prolonged use or in absolutely massive spells that are probably worth melting a staff or two in the long run.

[@Hero] Not sure which one you're using yet but depending on the size/complexity and autonomy of Diana's magic constructs, that's a totally different field than generic elemental magic and likewise gets more complex the more elements you throw in. It works for Phoebus since he's only working with a single element (or whatever you consider plants) but most golemancers (placeholder term, don't quote me on that) stick with one or two elements, typically of the same state of matter, to start with. For example, the act of puppeting an ice construct and a stone construct are fairly similar, one made of fire and one made of stone aren't.

[@Crimson Flame] Minor gripe, and I get that's your gimmick and all, but I'd prefer an actual picture. Also, where'd you pull a goddess from? Even humanizing the world soul as a sort of earth mother figure wouldn't give you a tangible entity to commune with.
