Yes that's really nice and wait, what? Iconic evoker using Planar Bubble (an abjuration) as his primary awesome? That's like basing an Evoker on the Orb-spells or Maw of Chaos; efficient but not an evoker. While it does enhance your spells, the fact that the Evoker is a one-element miracle (while evocation encompasses them all and thus a master evoker should, IMHO, be proficient in them all and indeed, proficient enough to vary the energy types) doesn't really feel right to me.
Thanks, but I don't think it has the feel I want. Besides, War Mage is pretty insane; I think you might want to look at it too. It's in Age of Mortals. Adds damage to your spells on a per die basis. Yeah.
