I have a character that will be a 17 wizard 3 archmage when he hits 20th lvl. Now i have no plans to continue as an archmage and next level i will be epic. what class do i take? another level of wizard will give me only 2 new spells to add to my spellbook. but if i take any other class i'll be essentially starting over and won't gain any epic benefits from that class either. do i actually have to wait till i'm a 21 wizard 3 archmage (24th lvl) before i gain any benefits other than the epic feat every 3 levels everybody gets?
could i take a single level of sorcerer then pick up one of the epic level prestige classes that continues spellcasting advancement and apply it to my sorcerer spell list?
