At first I thought you could only use one martial maneuver a round, but after looking through Tome of Battle, I can't seem to find that explicitly stated anywhere. Is there really such a restriction and I'm just not finding it, or can you use multiple maneuvers provided their action requirements allow it (i.e. a move action Boost in the same round as a standard action Strike)?
There are only a few requirements for using a maneuver:
- You meet its prerequisites (including Initiator Level)
- You know it
- You readied it
- You’ve been granted it, if a Crusader
- You have not expended it since the last time you recovered
- You can and do use the action required for it
As you say, this means you can use more than one per round. In fact, that is exactly how the system is intended to work: while in a Stance (you should basically always be in a Stance, unless you were ambushed while sleeping or something), you use a Boost to power yourself up, and then bash your enemy with a Strike. If you use a Counter, you give up your Boost in the following round. If you want to change Stances, that replaces your Boost and you can’t do it the same round as a Counter.
