And this is with less than a day of time constraint at this level. By the way, don't forget that one Mythal can elevate one to divinity given enough prevalent and vanguard effects, and that's not to mention that you can use a Major Effect to mimic any item or power there is. Miracle at will? Can it be built as an item? Yes, please.
But leve 20 wizards don't have Epic Spellcasting.

The hint here is that a level 20 character is not Epic. You don't become Epic until level 21.
