Thanks!
Even though I was looking under C for Conjurer as in Volo's and missed them when looking for them in MotM I think the new format of having all the wizards under a "wizard" entry is a more functionally useful ordering for utility when wanting to look up NPC wizard options. At least once you know to look under W instead of C.
Giving the new ones a quick once over it seems unfortunate that the ubiquitous NPC wizard attack power arcane blast is not a spell that could be counterspelled or blocked by a globe of invulnearbility in a wizard duel the way an at will attack cantrip could. Narratively the wizard NPC go to magical attacks are where you would expect spell countermeasures to be effective. Also narratively given wizard colleges these are the NPCs you would most expect to work similarly to a PC, I can easily see Hogwarts/Strixhaven type plots where you are mechanically interacting with NPC wizards with the same training/teachers as the PC's one and the difference in anticipated mechanical interactions would be jarring.
