eamon said:Why not replace Fighter(1) with Duskblade(1) for armored casting? it can hardly harm to be able to wear light armor without arcane spell failure chance, at the measly cost of one feat.
This would only help with your Duskblade spells, though.
How about a Duskblade 3/Wizard 4/Abjurant Champion 5/Spellsword 1/Unseen Seer 2/Spellwarp Sniper 5? It'd require Partial BAB increases and your DM allowing the Unseen Seer's 'Damage Bonus' to grant you sneak attack, so check first.
You'll get a BAB of 16 and 9th level spells, and you can use arcane channeling for *any* touch spell you know, and any area spell of 5th level or lower, while still getting an attack off that round. Energy Drain, Imprisonment, Polar Ray... you can channel whatever you'd like as long as you have spells, and then switch over to your 4 attacks per round. I'll admit, HP would be a bit light with this, so be sure to cast anything you know that grants extra HP (channeled Vampiric Touch + False Life, for instance).
