There is such a wonderful world - the Reincarnation of Alisara. There are a huge number of skills, races and other things. The enchantment is also there, and, best of all, the author led the gg along the path of enchantment. The only problem is that the World level can be very high, somewhere probably level 6, because the legendary creatures there can do the same thing as level 4. And there are also gods, and something above them, but this is a completely terrible spoiler.
A feel like a good world for him to travel to real quick would be the MCU or Marvel comics for the infinity stones the reality stone would be pretty useful if he could absorb some powers from it and considering they were made from the Big Bang maybe he could get some insight on universal creation or something
enchanting in the games of elder scrolls is pretty broken, but the enchanting in the lore of elder scrolls might be something you want to look into, Neloth in Elder scrolls is considered the greatest enchanter to ever exist and can fight daedric lords and gods for several days, and even repel them from the world mundas if he wants to, they downplayed him quite a bit in skyrim but in eso you see him fight off Nocturnal, Malacath, and Mehrunes Dagan i think, at the same time for several hours, before just locking them away, purely with enchanting
