Bladesinger
Bladesingers are elves who have blended art, swordplay, and arcane magic into a harmonious whole.  In battle, a Bladesinger’s lithe movements and subtle tactics are beautiful, belying their deadly martial efficiency. 
Multi-classed fighter/wizard are the most obvious candidates for the prestige class, although any elf who can wield a martial weapon and cast arcane spells can become a Bladesinger.  Bladesinger ranger/wizards, rogue/wizards, and even bards are not unknown.
Bladesingers command great respect in most elf communities, and NPC Bladesingers usually serve as itinerant guardians and champions of the elf community at large.

	Spellcasting Ability		Bladesingers continue training in arcane.  Thus, when every odd Bladesinger level is gained, characters gain new spell casting ability as if they had also gained a level in a arcane spellcasting class they belonged to before adding the prestige class.  They do not, however, gain any other benefit a character of that class would have gained (improved chance of controlling or rebuking undead, metamagic or item creation feats, and so on).
				This essentially means that they add the levels of Bladesinger to the levels of some other arcane spellcasting class the characters have, and then determine spells per day, spells known, and caster level accordingly.  If a Bladesinger has more than one spellcasting class, he must decide to which class to add each level of spellcasting.
	Bladesong Style (Ex)		When wielding a longsword or rapier in one hand (and nothing in the other), a Bladesinger gains a dodge bonus to Armor Class equal to his class level, up to a maximum of her Intelligence bonus.  If the Bladesinger wears medium or heavy armor, she loses all benefits of the bladesong style.
	Les. Spellsong (Ex)		When wielding a longsword or rapier in one hand (and nothing in the other), a Bladesinger of 2nd level or higher can take 10 when making a Concentration check to cast defensively.
	Song of Celerity (Ex)		Once per day a Bladesinger of 4th level or higher may quicken a single spell of up to 2nd level, as if she had used the Quicken Spell feat, but without any adjustment to the spell’s effective level or casting time.  She may only use this ability when wielding a longsword or rapier in one hand (and nothing in the other).  At 8th level and higher, she can quicken a single spell of up to 4th level.
	Gtr. Spellsong (Ex)		A Bladesinger of 6th level or higher ignores arcane spell failure chances when wearing light or no armor.
	Song of Fury (Ex)		Whenever a 10th level Bladesinger makes a full-attack with a longsword or rapier in one hand (and nothing in the other), she can make one extra attack a round at her highest base attack bonus, but this attack and all others that round take a –2 penalty.  This penalty applies for 1 round, so it also affects attacks of opportunity the Bladesinger might make before her next action.

Restrictions		A Bladesinger is forbidden to teach non-elves his art.  Any Bladesinger who does so may face stiff retribution from the elven community at large.
