I've got a racial limitation of being Lupin, due to story elements. I've tried going ghost when my Swordsage died, but the DM won't allow it.
I'm also limited right now to level 2 and soon level 3, so I need elements that get the thing to work early on as even just a faint glimmer. I've so far accomplished this by going battle sorc, taking the feat near the back of complete arcane and gaining access to Tune of the Dancing Weapon as a level 1 sorc. Just have to make a caster check of 8 and I can cast a 2nd level spell at level 1. Later I get to keep that extra spell slot.
Right now, My build goes down Battle Sorc until I can reach EK. The MotUH is nice, and was most of the inspiration of the character, but frankly.. not being able to really do what I'm looking for till level 10+ and then only being able to do it once or twice, and not being able to metamagic on it. (To get prof with all M weapons, I took Duskblade, so I'm having more magic)
(What the heck does swordsage, warblade, cabinet trickster and mindspy even do for that build?)
