Even without all arcane casters, once my wizard had 9th and 10th level spells, and Improved Initiative, and Epic Initiative, for a whopping +7 to their initiative rolls, which is basically an “I go first,” button. Then the hard part was deciding which way I was going to blast them into oblivion.
Hell I “one-shotted” the first Lich we ran into with a perfect roll on my Time Stop, and decent rolls on the ensuing 7 Delayed Blast Fireballs. I stopped using that particular combo in caves after that, since it collapsed the one we were in, and we had to ensure the lich was dead with Xorn Movement.
At 10th level spells, casters can simply make 10th level versions of any spell of lower level, and you can make literally any spell you’d like. If you make it too powerful for your current abilities, and attempt to cast it, it kills you, and IIRC that’s one of the few ways to permanently kill an epic level wizard. We die all the time, have Contingencied True Resurrections prepared for every time you get in combat. They last for years so this can be done well in advance.
I believe that those are referred to in 5th edition as the casters that broke the weave of magic and one of them accidentally killed Mystra for a second or two.

10th level spell? What sort of campaign is that?
Epic Level/ God Level Campaign.
3.0/3.5 had those rules. It was fun
