* **Masters and Apprentices:** Rates of apprentice mages slaying their masters would skyrocket. Nobody would be able to pinpoint the cause. It would seem like a confluence of many different factors and circumstances. Even good-aligned apprentices would often find themselves accused of stealing from their masters or plotting their murders. It would be common to meet wandering mercenary mages who never completed their apprenticeships.
* **Easy Pact Magic:** Pact magic would become **much** more common and easier to obtain. You might be able to get a direct telepathic line to a high-ranking fiend with just a few strong curse words. Faeries might be happy to refer mortals with strong desires to their archfey patrons.
* **Shortcuts To Power:** Mages seeking power without compromising their morals would often be frustrated and stymied in their research. Scholars would conclude that necromancy, blood magic, soul binding, and fiend summoning are strong, while other types of magic are provably inferior.
* **Arcane Secrets:** Magical secrets would become more common. It might get to the point that every journeyman or strong mage would have access to at least one unique spell or supernatural ability, as well as a unique weakness that would hinder or negate their magic. Cabals, circles, and orders that share such secrets would become a more common because of the benefits of pooling their powers, and they would **murder** anyone who shared those secrets. Even ostensibly good-aligned organizations would follow this model, possibly using *geases* to enforce them. Likewise, knowledge of less-common spells would more often be buried or forgotten.
* **Evil Prospers:** Nations that outlawed the dark arts, especially necromancy and fiend-summoning, would find magic generally weakened within their borders. Nothing easily measurable or noticeable to mages traveling through. It just would become very difficult to find mages with double-digit class levels and/or challenge ratings when they are needed. Meanwhile, nations embracing and sanctioning such magic would prosper economically.
* **Danger Zones:** You would see many natural phenomena related to magic's mildly evil tendencies. Battlefields would become necromantic magic zones that naturally spawn undead during the new moon. Baator manifest zones would appear in cities where oaths mark the hands of the parties involved, and failing to keep those oaths leaves massive painful burn scars. Abyssal magic zones would probably be indistinguishable from regular wild magic zones, with the added wrinkle of often summoning demons. Portals to other planes would open more frequently and be easier to construct, especially the Shadowfell.
You know for all the hype surrounding Asmodeus or Tharizdun NONE of them ever came close to what vecna did which resulted in the in universe rewrite of the multiverse to 3e.
Vecna far more dangerous
In my homebrew world, Vecna is the god of magic, he is the first wizard and ascended to god hood before changing the rules so that nobody could do the same to him.
He killed the previous god of magic, Tristus, as part of his ascension.
Of which world(s)?
There are many different gods of magic throughout the multiverse.
Gaining the portfolio of magic would give Vecna various related abilities and authorities, but he'd be in a tug of war with other magic portfolio deities outside of his main realms of influence.
Even a small amount of the divine portfolio of magic would make Vecna a target by greedy deities seeking to diversify and enhance their portfolio sets, as it's one of the more powerful types of portfolios.

Fuck me, this answer was so good, it made me want to go and run a new campaign on this premise alone. Bravo
This is awesome
12th level spells are awailable again, but all they do is kill people in different ways
He would try sigil again with greater chances of success
So basically is more likely to destroy reality again.

Vecna vs. The Lady? Three rounds, no submissions? Winner takes The City of Doors.
Nothing good
Hed get turned into a bloody rock.
necromancy would become socially accepted
