A) I knew I should have said Gate.
B) I'm not convinced Earth Spell actually bypasses the spell level cap of Heighten. After all, it's still Heighten that's increasing the spell level ("you can use the Heighten Spell feat to greater effect"), not Earth Spell. Earth Spell reads like it works within the Heighten Spell feat.
And I said Teleport. I was wondering how you got all the Conjuration spells, not just (creation) and (summoning), while seeming to miss Necromancy, Illusion, Abjuration, Enchantment, and Divination.
