How would I go about building a wizard 6 with the following concept?:
He laughs at the very notion of immutable spell slots. Whether it's casting Unseen Servant 12 times in a day to help with the garden, or unexpectedly whipping out 2 or 3 more higher level spells than he should be able to, he always has just the right proportion of force for whatever he needs to do.
So basically he excels at altering the number of spell slots he has to play with, with a little flavor of spontaneity.
My attempt at building him/her ended up as a Venerable Grey Elf Focused Diviner with the Spontaneous Divination ACF.
As for feats, he/she has Arcane Manipulation and Versatile Spellcaster, combined with Spell Mastery, to mess with spell slot amounts.
Spell slots could range, at 6th level, from 30/7/7/3 to 0/4/4/9
So, is there anything I've missed that could make this even more flexible?
E6 rules, meaning unlimited number of feats.
