Scott -
OK, first thing : Spells
As we talked about earlier, your spellcasting should be as such:
Sorc 6, EK 4, AC 5, Practiced 4.
The 4 from practiced ONLY applies to the effects of spells, not to how many you can cast, how many you know, or what level of spells you can cast.
For anything on the "spells per day/Spells known" chart, you are effectively level 15.
Your CL for determining the EFFECT of those spells (damage dealt, range, duration, etc) is 19 (15+4). For Acid spells, this would be 20 due to your acidic splatter feat.
So for example, your spells known would be :
9 Cantrips, 5 First Lvl; 5 Second Lvl; 4 third lvl; 4 Fourth Lvl; 4 Fifth Lvl; 3 Sixth Lvl; 2 Seventh Lvl
Haven't done the math yet, so not sure if you did this, but as the only character who took an INT boosting item, I figured I should remind you that INT bonuses from items do not grant Skill points/Languages, so with a +6 int item, your base int of 14 is what would be used for skill point calculation and languages known.
There is no fly skill in 3.5, what you can do is based off your maneuverability class and any applicable feats/spells/items.
Combat : you have your attacks listed with "off hand att at -2/-7/"
Two weapon fighting doesn't just give the -2 atk penalty to your OFF hand, it allows you to take one extra attack using your highest BAB with your off hand weapon, but you take a -2 penalty on ALL attacks made till your next turn.
You have several scrolls listed as 'made himself'. Please note how much XP you spent on this and how much you have remaining.
Also, why take so many crafting feats and not use any but that one?
On that note, I would not suggest more than one or two Crafting feats. If you're using it to gain extra gold at the cost of XP, just take one feat and craft some expensive stuff. Taking multiples is only useful if you have specific items in mind you want to craft.
If its for RP reasons, I would still suggest against more than 1, maybe two feats, b/c you're seriously hampering your character.. Just SAY he's a crafter, give him one or two, and treat the rest as fluff.
Also on equipment, I see you've taken a weapon of Disruption - Be aware that special/important Undead (Bosses/characters) Will be protected from such mundane methods of dispatch.
