Not really sure about that Preferred Spell. The feat allows spontaneous casting of Scorching Ray with any desired metamagic added without increasing the casting time. On the other hand between pearls of power, a wand, and lesser quicken spell rods I'm wondering if that might be a trap. Dasterdly finish become available at level 13 and a target is much more likely to be stunned or cowering when your spells put them in that state (then again full round action, have to be adjacent to the target).
Hum I wonder if there is something I could take off the list to get sickening spell on. I suppose I could dump Cha, and put it into Con and loose Toughness. On the other hand UMD. Arcane Armor training also looks a bit questionable but it does allow casting a Mithril Shirt.
I'm also worried that the HPs are going to be low. On the other hand even if I put the level 4 and level 8 increase into Con the HP increase wouldn't kick in until 8th level. I'm thinking a belt of Physical Might +4 Dex, +4 Con would work very well with this character, but that is also a high level item.
