Shit, I realized it still needs minor tweaking.
In addition to recovering a maneuver through meditation, you may also do so by making a skill check as a special action immediately after attacking a foe in melee. Roll a skill check against the opponent except the DC is equal to your opponent's AC or the normal DC, whichever is higher. You must meet all normal requirements of making the skill (such as the requirements for making a hide check) and the results of the skill check take place normally. You have the option of either making the skill check as a move action with no penalty or as a swift action by adding five to the DC.
In addition, you can instead roll the skill check as above except the DC is equal to your opponent's AC and the skill check has no effect except for the purposes of recovering a maneuver. You do not need to meet any requirements of making the skill check (such as the requirements for making a hide check) when making the skill check in this way.
The skill check can be made even if the attack was unsuccessful, but you can only recover a maneuver from a school associated with the skill check that you are making (Desert Wind for Tumble, Shadow Hand for Hide, etc). You may only recover one maneuver each round. You may not regain a maneuver you used in this turn, and you may not use the maneuver you gained until your next turn.
There, no requirements required for making a special hide check only to recover a maneuver and not also hide.
I'm obviously okay with what I wrote so feel free to adjust and then put it into Swordsage.
