I rebuilt my Bladesinger with Wizard6/Swiftblade9/AbjurantChampion5. Apart from having no RAW-song-like abilities, I find this feels a lot like a 2nd Edition Bladesinger.
The main issue with going Bard-based, is the fact that the 3.x Bard spell list differs too much from the Arcane spell list in 2nd Edition. It requires some Sublime Chord.
That was the idea if I went bard. A Wizard Swiftblade (the first place I looked to) would have most of what I'm after, no doubt, though it does beg the question can that be further optimized? Assuming early entry on the spell requirement and the feats fulfilled (easily enough since all but one of them are needed for SB and AC anyway), how would Spelldancer 2 look? That'll add even more Ref, while also granting autopersist and Evasion. Their prescient magical sense I can emulate with one spell (also precluding the need for Uncanny Dodge), and the speed aspect is there for sure, along with the "fuck you, you can't hit me in your dreams" aspect of the 2nd Ed parrying option. Is there a way to match the +10 or so bonus an optimized Bardic build can get with a Wizard base? I assume both would use Knowledge Devotion and Greater Magic Weapon, so that leaves boosting +to hit/damage with other means (non-item if possible, though another +3 is easy from that war god armband) to match IC. Now I'm also going to go hunting for a possible 9th level spell Swiftblade bard build, but in the meanwhile, I can get Sor/Wiz spells into the entire progression of a bardic build, assuming I've got room for PrC Pal 1 in there.
EDIT : And what's the closest we can come to emulating the 9th level ability of Swiftblade, i.e. 3.0 haste?
