Is it still possible to cast 10th level spells in the Forgotten Realms or has Mystra imposed further restrictions following the events of Karsus’ Folly? Does there exist any schools of magic capable of casting 10th level spells? Mystra’s Ban on 10th level spells remains in place. Certain rituals can create magical effects akin to tenth level spells, if legends can be trusted, but they require the cooperation of many powerful mages and/or sorcerers.#Realmslore

Has there ever been a push to use a different word for character level and spell level? Oh, yes. I recall fervent discussions at early GenCons (2e era) of the confusion engendered by having dungeon levels, character levels, spell levels, and so on, all in the game, as a barrier to newcomers learning the game.

Could you cast such a spell in the Feywild and reap the benefits in the Material?
How far does Mystra's Ban travel?

1)
Mystra’s Ban only extends throughout Realmspace (where the Weave reaches).
The problems with casting ANY mighty spell on a Plane of Existence other than the Prime Material are: attracting undue attention from local dwellers, and: most casters don’t fully… 2)
…understand the nature (natural workings/cycles) of any plane, and could cause great chaos/instability, dooming themselves and ending up with a different magical effect than they intended.#Realmslore— Ed Greenwood (@TheEdVerse) November 3, 2020
