Ok, I an old fart. Some the stuff you are mentioning I never heard of. I start back in 1E so what is
School of Invention?(sounds like Ravenica )
Artificer (what if get from forums is they create stuff which do spell stuff)
Jolo (I not going to google my mind may not handle the result)
Of course back in the day you could tell my wizard apart from Morrus' wizard. My wizard look like James Bond from the original Casino Royale in a three piece suit and white Persian cat. Morrus' look like the wizard kid from the Saturday morning cartoon but with white hair.
Shi'ar are Al Qadim wizards what have a special mini genie like familiar they use as a spellbook. The send this Familiar off to fetch spells for them. There is more to it then that, but it's the basics.
