Adaptive Style( Tome of Battle: The Book of Nine Swords, p. 28)
With just a short period of meditation, you can change your maneuvers and tactics to meet the threat you currently face.
Crusader, Swordsage, or Warblade Level 1st,
You can change your readied maneuvers at any time by taking a full-round action. If you're a crusader, your current granted maneuvers are lost and you gain new granted maneuvers as if you had just readied your maneuvers for the day.
You can change maneuvers only by spending 5 minutes to do so.
