The Martial Study feat states:
Select any maneuver from the chosen discipline for which you meet the prerequisite. If you have martial adept levels, this maneuver becomes one of your maneuvers known. If you do not have martial adept levels, you can use this maneuver once per encounter as a martial adept with an initiator level equal to 1/2 your character level.
Now, there are very high level maneuvers that simply do not possess any prerequisites, therefore allowing a first level character to select shadow noose/shadow garotte/shadow blink/mountain tombstone strike/.... as his maneuver, as per the first sentence quoted above.
The problem is, I have yet to see a restriction limiting the use of maneuvers to those that match your initiator level -- the only restriction I've seen is the Maneuvers Known table, which limits the maneuvers you can select as a martial adept, and that is obviously a general rule overridden by the specifics of the feat above. Is there anything I missed, or is it really simply this broken?
