Magic Missile Build?

There's really no point to heighten spell if the focus is all on spells that don't allow saves. You can use any spell slot to cast a spell of that level or lower without heighten. Heighten just lets you boost the DC by using a higher level slot.

Well, I'm forced to agree with you after checking the rulebooks. I'll edit it out. First time I heard of that, though.
