Speaking of Heroics, I have a little problem as a DM and could use some advice.
One of my players can cast Heroics and uses it to take the Martial Stance from Tome of Battle. This allows him to choose any maneuver from a certain stance every time he casts it, as long as he meets the pre-reqs. This opens up his spell caster to be every bit as strong as a fighter and he overshadows ever other member of the party because he can do pretty much any maneuver.
Is there anything I can do in the face of this? For instance, is there something that says he can't? Otherwise, I just have to outlaw Heroics, which is ridiculous in the first place.
