Nice combo, to bad its not legal. Bladsinger has a prereq of +5bab and spell sword has a prereq of +4bab You need a few levels of fighter or wizard before you can enter either of those classes.
My players are trying to convince me that the mage with permenant detect magic can see through illusions and invisibility. I say no because there are spells like see invisibility and true seeing that would be replaced by a 0 level spell. Can I hear arguments and references either way.
Thanks
