Add Martial LoreArcane Maneuvers:
An eldritch knight gains access to maneuvers as a warblade of his class level. He does not gain the warblade's recovery method. Instead he may recover a single maneuver as a swift action by expending an arcane spell slot of a minimum level one below the level of maneuver (eg. refreshing a 4th-level maneuver would require a spell of 3rd level or higher).
Okay, two additions.
I was just thinking about how I usually give my ToB homebrew maneuvers "as an X" and was wondering about alternate methods of initiating. No, this isn't just turning maneuvers into extra spells - you can still ready maneuvers as normal between encounters, without burning magic. Anyway, this gives you a use for those low-level spell slots.
