Prerequisites: Intelligence 19
At the end of a long rest, you can expend one of your Maneuver Dice to put an undisclosed contingency plan into place.
Until you activate this Maneuver again you cannot regain this Maneuver Die. You can only have one contingency plan at a time.
As an action, you can reveal your previously undisclosed plan (which you make up at the time of its reveal) and make a DC 20 Intelligence check. You may add a skill the DM deems appropriate to your plan. On a success, your secret plans and preparations take effect perfectly as you described them.
The cost to execute the plan cannot exceed 5,000 gold, and the effects should not exceed those of a 7th-level spell.
For example, you might reveal that you secretly purchased a perfect spell scroll last time you were in a town, or that you paid a mercenary band or airship to come to your rescue.
